Re: Ez wiring help
It looks like one of the terminals is broken off terminal 4 to be exact. I guess that power out to wiper terminal...

On motors without it, just run your +12V feed wire to the "(2) Power" terminal as usual and branch off from that with a second short jumper wire over to the washer. |

Re: Ez wiring help
Ha all good sound good I was scratching my head while trying to see where it might be broken I'm just hoping everything works once I'm done I don't see any wires to run to that plug on the steering column tho according to the ez wiring diagram just runs straight back and to the column plug for signals emergency etc

Re: Ez wiring help
So on the plug for the dash I'm left with the 1,3,8,12 terminals in still unsure about what these are. Still figuring out the ignition switch. Will be wiring the wiper and heater today hopefully. There's nothing that goes to the back up switch... And I need to find a way to run power to my dome light.

Re: Ez wiring help
So if I understand this right the 3 terminal will get the red power to cluster wire from the harness
The sending unit which I guess is pink will run to the 4 terminal The brown instrument panel light runs to the grey for the heater lamp from the heater lamp to the cluster. And I'm just going to cap off the ammeter wires I think...

Yes, the wire that runs from the fuel sending unit goes to terminal #4 on the cluster plug. Assuming EZ wire is using brown for the instrument panel light circuit, yes you'd run that wire to the heater control lamp and to the cluster connector's #8 terminal. As I mentioned in my earlier reply to 72ChevyMan1 in this thread, the EZ wire harness might not have the charging system configured in a manner that will make it easy to hook up the stock ammeter. So just capping off (or removing) those wires off is probably a good idea. And you might want to check with TBone1964 about getting a voltmeter that will fit in place of the ammeter. The voltmeter wiring can simply tap into the temperature gauge's existing power & ground connections so it's easy to hook up. |

Re: Ez wiring help
I'll probably just buy an aftermarket one I can mount under the dash at some point. Red is described as gauge power according to the wiring diagram provided.

Re: Ez wiring help
So now I need to get my ignition switch figured out. On the color coded diagram I notice the brown and brown/white wire run to the same place on the fuse block. Temp guage and brake warning are run through which I'm guessing is the acc side of the switch. The coil ign and bat term all are just direct to. Am I correct in saying this?

Re: Ez wiring help
So looking at the wiring diagram again for the dome light now, it looks like my truck didn't come with door jamb switches I'm wonder if I run this instead of going to the switch would I run power off the same fuse the brake switch and headlight switch are run off of? Bypassing the door jamb switch?

I am a little confused. Reason being is I have found different diagrams that do not have the same Colors as my plug. I do not have a tach so I only have 6 holes on my cluster. Does that make a difference? If not do I still use the quoted reference to wires? |

Re: Ez wiring help
What is your color code? Mine is no tach and matches the diagrams

Re: Ez wiring help
Ok so I'm working on the ignition switch now which is pretty much the last of the dash except the dome light getting wired in and I'm looking at my diagrams and the only one I can't figure out is the brown/white wire from the ignition switch not sure what that wire is about? Also the harness from ez has a black wire splices from the (red) ignition switch power, not sure what this is.

This is how the key is wired. The black arrow to the left is the brown wire to accessory and the wire just below it is brown/white stripe wire. I do not know of a black wire spliced in with the red power wire. Black is usually designated as a ground wire and it certainly wouldn't be connected with a red power wire. Here is the cluster connector for the gauge dash. it shows the stock wire colors and tells what terminal they go to and where they come from. They may be different from the EZ harness you have.

Re: Ez wiring help
So is this a deletable wire then I have external rectifier. And any info on the reverse lights I done see a connector or plug on the trans

I don't know what you mean by (external rectifier) unless you mean the external voltage regulator mounted on the radiator support by the left headlight. Here is some info on the switch, https://www.google.com/webhp?sourcei...+switch&spell= Your reverse lights are a simple circuit . You should have a fuse on the fuse panel that says reverse or back-up with a 10 ohm fuse, IIRC. There should be a dark green wire running from it to the switch on the transmission and a lighter green wire from the switch to the rear of the truck to the back-up lights. I had to search your build thread to be sure you had a standard transmission. Do us a favor and revise your signature to include more information, or at least put it in your thread. I can't be sure what b/U light switch you are supposed to have because there are quite a few. It should mount near the linkage for reverse in a port on the trans.

I don't have door switches for my headlight so I assume bypass that and run it straight to the dome light. Also I don't see any type of harness or plug for the Saginaw 3 speed. Would my reverse switch be the one on the column located inside close to the fire wall? I appreciate the patience like I said I'm not too good or comfortable with wiring but there's only one way to learn..

The factory tach (when present) goes in the otherwise unused hole between the speedometer and fuel gauge. It is wired up with it's own separate harness so it doesn't connect into (or result in any changes to) the cluster connector pin-out that I posted earlier. Quote:
As a somewhat related side note, there is an electrical switch on some Saginaw 3-speeds ... it's located on the side cover right near the 2nd/3rd shaft and is used for the TCS (Transmission Controlled Spark) emissions system (which is commonly disconnected). |

Re: Ez wiring help
Ok ha that switch it not exist any on my trans. So since I have no reverse light wire how will I go about running this?
The ez wiring has a white exciter wire that runs from the harness to the front section which runs to post 2 and 4 on the voltage regulator then 1 and 2 are run to the alternator plug. Alternator has a red which I assume is power and a ground terminal.

Re: Ez wiring help
Ok I'm working on the ignition and reverse lights now. At some point I will have to wire in my tach but that's not a huge concern ATM. I'm wonder where I run power from to the dome port on the headlight switch and where I would run power from to the reverse lights. This is essentially the end of my wiring. The rear end will happen once then bed goes on but its all routed to the back already. Should I run power from the battery with an inline fuse for these connections?

The factory wiring had a 10A fuse in the fuesbox for the circuit that supplied power to the reverse lights. If the EZ wire harness has a similar fused power feed circuit for the reverse lights, just run that wire to one terminal on the reverse light switch. And then run another wire from the other terminal on the switch back to the lights. Quote:
The alternator's power output stud (often marked BAT on the case) uses a heavy gauge (usually red) wire to feed power to the main distribution point. The ground stud on the alternator isn't used in all applications since the alternator is case ground via it's mounting brackets to the engine. Quote:
Power for the dome light (factory orange wire) originally came from the TAIL/STOP/PARK/DOME fuse in the fusebox. This is the circuit that also feeds power to the portion of the headlight switch that controls the tail & park lights. So you can tap into this same power feed to supply power to the dome light.

Re: Ez wiring help
Sorry yes I do infact have the column switch it's the running power to said switch. There doesn't appear to be any circuit labeled or designated for reverse lights.
So the dome light I just branch out via the stop switch circuit prior to the actual brake switch? Then from that triple split I would run it to the headlight switch and back to the dome light since I don't have door jamb switches? Also my ignition switch is looking merky it states that Harness side Ign sw coil-pink goes to ign Ign sw ign-brown goes to ign Ign sw power- red with a black splice goes to bat Ign sw start- purple goes to start Ign sw acc- orange goes to acc Switch side is... Bat-red Sol-purple Acc-brown Ign-pink So that means I have pink and brown running from harness too brown ign terminal in switch. Would these get spliced in together? Btw my only regret is not getting the larger harness

Re: Ez wiring help
I will give this a try not sure I can post pictures from my phone of the diagram but will when I get home if not.

the orange wire on the pic gets power from the brake light circuit which also feeds your dome light your dome light has 2 wires: 12v+ and a ground wire: the 12v+ comes directly from the orange wire to turn on the dome light you need to ground the dome light, either thru the headlight switch or the door switches the pic from post #5 shows the white dome/courtesy ground this is where you hook the ground wire for the dome light to turn it on the reason the dome light uses a grounded switch is that any ground can turn it on whether that ground is the headlight circuit or door pins it does not matter while your pickup only has one switch, the 4 door cars of that era had the headlight switch and 4 door pins any door pin also goes to ground your brake circuit is currently feeding the side marker lights, dome light, the reverse lights and (obviously) your brake lights this is the same as the original brake circuit
