Cool! How about a high res to krue1@bellsouth.net

JIMS1972STEPSIDE · 02-20-2007, 09:33 PM

Hi, could I get a hi rez sent to Hogheadone@charter.net

Chlsnk · 02-16-2009, 01:34 PM

Has any one made a diagram for the 73-87 gen of these trucks?

Twisted78SS · 02-16-2009, 04:36 PM

I too can post them on my sites, the more the coverage the better!

Pm me and I'll get to it right away.

I've got plenty of space on my website as well, and no ads. Give a holler if you'd like me to post it for you.

BTW, for anyone that needs a reader, there is a much better alternative than using the standard reader from Adobe. The Adobe version takes forever to load up on some people's machines.

The better alternative is Foxit Reader. It's fast, it's free, and it works great!

And no--I don't get anything for tooting their horn... ;-)

Will these diagrams work for the year 82 also or is there alot of diffrences?

actconstruction · 04-06-2010, 11:55 PM

Do you still have these documents in hi-res? There is an awful shortage of wiring diagrams like this, even in my vehicle specific repair manual. This is awesome. If you still have them, could you send to actconstructiononline@yahoo.com ? Thanks in advance. Keep up the good work. People need diagrams for these old vehicles that have been cobbled together real bad over the years.

First of all welcome actconstruction!

If you look at the post #163 you will see links to all of the diagrams. If you download the hi-rez version you'll have a nice big file that you can print out on two regular pages or a legal size.

Good luck!

I have purchased a replacement ignition switch connector (pigtail) from BWD. It has 10 wires coming out of it, but not in the same places as these diagrams. The original one was damaged and missing wires when I got the truck, so I have no point of reference here. The connector body and holes are identical, just don't have the same wires in them. Does anybody have a switch diagram maybe, or know what to make of this? I've attached a crude sketch.

actconstruction · 04-13-2010, 12:44 PM

Okay, so I just went and looked at a different brand replacement. It matches the pinout I posted yesterday. What gives? Are these wiring diagrams wrong, or is there something I'm missing here about the replacement part. I know somebody out there has replaced their ignition switch harness. HELP

fixit-p · 04-13-2010, 02:51 PM

Are you using part number PT298 the colors are not correct on your connector (the diagram is correct) but will still work below is a pic from BWD website for part number PT298 with the correct color code. Note the purple and brown wires.

actconstruction · 04-25-2010, 12:28 PM

Toejam, the bottom wire seems to be a double of the wire that has the fusible link on it from the battery. Look where the power wire splits into four wires. One of those wires is supposed to have a fusible link on it and doesn't. They go the same place. I think the wire on the top is the same deal. It's trying to show the two wires with fusible links on them, but instead of showing it on the proper wire, the wires have been duplicated.

The diagrams are great but they aren't for a GMC with the four eyes up front and AC. Anyone have a diagram for a '68 GMC with factory AC?

Peanut74 · 12-16-2021, 10:07 PM

Thanks for posting this. Been looking for one to help make sure I don't burn my truck to the ground. I appreciate your effort as I know it was not a easy job to do.
