Re: AD wiring

Talked to Mark at MAD electrical. Nice guy, he will answer any all questions. Ordered some stuff, the relay kit and booklet. He is in the crimp solder insulate camp.

I've used solder before, makes a hard area in wire. I think Marks way is just a tiny bit in the connector but a good crimp is enough right? I don't want to risk overheating my new wires...

Got my order in the mail, got a new crimping tool and a new heat gun. Next I'm ordering ignition switch, headlight switch and using his kit I'll order additional relays using part numbers.

Re: AD wiring

I'd say it's like a good/better/best situation.

Crimp connectors (decent quality) with split barrels = Good

Crimp connectors (good quality) with brazed barrels = Better
Something like 3M. The plastic around the terminal is also much higher quality, and won't split/crack when crimped

Crimp connectors (good quality) uninsulated, solder in, heat shrink over = Best



Longevity vs. your budget (money and time)

Re: AD wiring

A year and a half later and I am going to finally get the wiring started!

I plan to order a few things this Friday and I'll post a list with links before I do to get some feedback. Until then and until the stuff comes in the mail, I have a couple of small things to do. It has been raining the last couple of days and I have discovered a couple of leaks. For example, I didn't think until now to get new wiper seals. I'll also try to start putting the door seals on in the next little while too.

I have a much better understand of what I need to do than when I first started this thread but I will still ask a few questions as I go.

Re: AD wiring

sometimes easier to get a headlight switch with a plug in on the back instead of the screw on style, if you ever have to remove or work on the switch it is easier to unplug than unscrew it. unless you leave enough wire back there to let it droop when undone from the dash so it falls below the level of the dash.
some heat shrink vendors sell 4 ft lengths but those are fine too. a good pair of crimpers is a must, try not to use the ones that simply press 2 sides flat. use the non insulated connectors and shrink tube, that way you can see the crimp and then the shrink tube insulates it.

Re: AD wiring

I have been planning my '47 Panel truck build for awhile, and have just started designing the electrical system. I'll be using an '88 k2500 for the donor, but will retain the stock controls. Here is what I came up with for the stock starter switch and foot starter button. I'll mount the foot button mechanism to actuate a remote mounted momentary button. I have been scouring the web looking for schematics and design ideas, haven't seen something like this though.

Re: AD wiring

I saw a headlight switch like that that came with a plug. That's probably a good idea.

If there a good all around kit that has all the connectors I need uninsulated?

Re: AD wiring

Not you send you down a rabbit hole, and not necessarily automotive-focused, but places like Mouser or Allied Electronics have the terminals you'll need in any configuration you can imagine, and then some.

Re: AD wiring

Just thought of adding a terminal block to my buy list. Do I need one or two?

And I also have a headlight relay kit from MAD already too.

Re: AD wiring

I'm assuming it is good to have these. Here's a picture of a set up. Should I copy it? I'm finding these red and black blocks all over the internet.

Should I have a third one inside for dash stuff? Like gauges? Or does each light or run off one fuse and tied together some other way?

Re: AD wiring

if you are going to bring power into the cab and feel the need to have a big power block in there then think about the possibility of running a mega fuse near the battery, to start the circuit with a fuse rather than run a large cable through the firewall or floor with no circuit protection until further down the circuit. those big lug style power blocks work pretty well but you need to think about the possibility of a short and if that happens the cable would burn back all the way to the battery or the battery could blow the lid off depending on how much duty it has been going through lately and the amount of gas it is venting. if installing the battery in the cab keep the venting idea in mind. there are some holders that will accommodate a couple of mega fuses if you require that much protection. also, there are bulkhead connectors that would allow the battery cable to be brought through the firewall or floor without the worry of a short from using a grommet.
these are all the reasons why newer cars have a fuse/relay box under the hood. they usually have a mega fuse built in early in the circuit for system protection.

Re: AD wiring

one thing to look for in a crimp connector is whether the crimp area is a solid tube or if it has a split in it and the ends are just really close together at the seam of the split. I say this because the ones that are not a solid tube in the crimp area will sometimes actually split apart at the seam and that makes the crimp sorta suspect. I avoid that style when possible because they are ok to use if you get the crimp placed in such a way that the split is always on the back side of the crimp but they just take more time to do the crimp because you have to look at the connector and orientate it on each terminal you are connecting. I would rather pay a couple bucks more for some better connectors and just crimp them however they fit into the pliers. some connector styles are unavoidable to have a split, and that is fine we can deal with those as needed, but why not start out with connectors that lead to a better outcome and have less problems overall.
I try to use non insulated connectors whenever possible for that exact reason, plus you can see the whole crimp when it is done to look for issues. they also take up less space in the harness so if you have a couple of connections close together the harness doesn't have a huge lump in it. use double wall shrink tube on each connector as well, it has like a hot glue inside so it helps seal the connection. it comes in different colors if you want to keep circuits marked by color.

Re: AD wiring

battery cable also comes in different grades and color. I have used welding cable in some areas because it has more strands for the same gauge so it is more flexible in areas where the cable needs to bend around corners etc. red for pos and black for neg also makes it easy to figure out by someone else later on.

Re: AD wiring

remember to size the cable for the max load it will carry. neg cable needs to be the same gauge as pos. the smallest cable in the circuit will become the weakest link in the electrical chain. fuse each circuit accordingly to the max load it will carry. use relays in circuits that will carry more load than a regular switch should be expected to handle plus the relay idea keeps the wire gauge size smaller in the dash area because those wires become signal wires instead of circuit load carrying wires. the under dash harness becomes more manageable because it is more flexible.
make sense?
look under the dash on newer cars, the wiring is smaller gauge because there are more relays running in newer cars. the relay is under the hood close to the battery so the large wire circuits are shorter, for less voltage drop issues, plus the harness in the cab is smaller gauge wiring so easier to work with and less chance of something rubbing through on an edge and melting an entire harness or catching the car on fire, plus the bulkhead connector is smaller gauge wiring so more easily sealed and smaller overall.

Re: AD wiring

I'm overthinking power supply. Power for gauge lights, for example, run through the ignition switch right?

Power to the box. Couple diagrams I've found looks like either power goes from battery to terminal block and then to fuse box or I think one showed power off starter?? To fuse box. I guess power could go directly from battery to box too.

So I need a mega fuse or fusible link in between the battery and the box or between battery and block right?

The above picture looks like a direct power feed to block and then a fusible link between block and fuse box.

It looks like these blocks help with having a common spot for power. I just need to make sure I use the right size wires. I want to use one to run power to my relays, horn, fan, headlights....

My c10 only had one block. The above picture shows two. How many do I need?

Re: AD wiring

if you wanna bring a big power supply into the cab then use a mega fuse near the battery then run wire to your insulated stud under the dash or wherever. the black ground stud is really not required as long as the cab is grounded well. the mega fuse will protect the power supply to the stud, the stud would supply power to individual circuits each protected by it's own smaller fuse through the fuse panel under the dash (usually).
the issue with taking power from the starter is that it is difficult to get a mega fuse close to the starter in order to protect the rest of the big wire that feeds the stud under the dash.

Re: AD wiring

if you have an under dash fuse block and wiring harness then just use a mega fuse under the hood, near the battery, to supply that and then use the fuse box under the dash to do individual circuits.

Re: AD wiring

I called Mark at MAD Electrical again. He said similar to you dsraven. Well, he seems to think fusible links are better.

I spent a long time on the phone with him and forgot to ask if I should use a relay for rear lights.

He recommended a separate relay for each of the following parts. Horn, low beam, high beam, fan x2, driving lights, a/c. He recommended relays with a plug with 14 gauge wires and 18 gauge fusible links.

He also recommended adding a diode from the alternator. And two terminal blocks, one on firewall with a power feed to dash, and one closer to the front for the lights etc..

Re: AD wiring

a fusible link is basically a fancy and smaller mega fuse or a short length of wire that is placed in the circuit. the wire is usually a couple of gauges smaller than the rest of the circuit wiring so that section of wire "fails" before the rest of the circuit gets damaged. if it fails that means the wire melted and burned apart so there is no more wire left there just a nub of burnt wire that needs to be replaced for the circuit to be useful again. the other style of fusible link, similar to the mega fuse, used in more modern cars is like a clear plastic box, in the relay/fuse panel, that has a short piece of wire in it of a certain alloy that will melt apart in the same manner. the difference is the box style is easy to replace once you figure out why it melted in the first place. fusible links are meant to handle the quick start up loads of things like heater motors or the like, stuff that would blow a fuse because they would draw more than the fuse is rated for. the fusible link can handle the quick start up draw and then the motor draw becomes less once it is running so the rest of the circuit isn't overloaded. more money and they use a different type of holder. to each their own.
here are a few links to both styles.
use relays in anything over 20amps and you will have no problems. heater fan, headlights, rad fan, fog lights, wiper motor, fuel pump, horn, etc. if using LEd lights the draw doesn't really warrant it but then if you don't like LED after and want to change your circuits would be set up properly.
there is also the circuit breaker idea but these are sort of a slow burn, like a fusible link, and shouldn't be used in a circuit that is for electronic equipment. the breaker may take a sec to blow and by that time it is too late for the electronic part which is more sensitive to voltage. the nice part is that they will reset themselves. the bad thing is that they will reset themselves even if the circuit is bad. they will keep going until they burn out.

Re: AD wiring

Is something like this OK? An inline fuse.



And the box style... you mean the aliexpress link?, is there a plug for that?
