Got my kick panels installed, Hood Release, Ground Bar, Hood Hinges with the Rubber pad (did not have one previously and had to modify some to work), and neutral safety switch installed (among a few other things). Have a Dk Blue and Green wire two pin connector that goes through the firewall via a grommet (next to the fuse box) that I am not sure how it will connect yet. According to the wiring diagram, it looks like the neutral safety switch. Will take information on it or pictures from your truck with it connected. Only have the one big hole to fill in behind the engine and a couple of firewall pad retainers to install along with the steering column, besides completing the harness install. Then hood, fenders, and complete the rest of the A/C install.

If all else fails, you could lop the ends off, and install male and female GM Weatherpak connectors as used on later model vehicles, though that's not the "correct" way to do it.

The safety start circuit is yellow and purple.  Dark blue and light green are for backup lamps.

It's difficult to know just how much you don't know until you know it.
In other words... if people learn by making mistakes, by now I should know just about everything!!!

Reworked my wire harness by replacing some of the wires and I cleaned it up a bit (still needs more cleaning and bought some contact cleaner yesterday). However, the labels on it were in bad shape and what was left disappeared when I tried to clean off the dirt and grime. It bothered me a great deal and so I bought some fine tip paint markers and relabeled the fuse block by hand. Would love to get OEM labels that would stick on and thought about a new harness, just did not think it was worth the money (> $500.00) since mine is in good condition.

In between the nasty storms, I installed my Cowl and Windshield Washer Hoses and nozzles. Saved me much trouble finding the pins for the cowl at the local salvage yard. Took care of a few minor things as well. More difficult and takes longer to put the truck back together than it was to tear it apart.

I'm cleaning up and getting ready to install the distributor harness and it has a wire for what looks like it goes to a detonation sensor that has not been used many years. The connector for the detonation sensor is gone and I do not have a detonation sensor on my engine. Was wondering if anyone uses a detonation sensor on their truck.

Got many small things done today. Working on my wire harness and should be finished with it in 2-3 days. I installed the ESC Controller today, the rest of my firewall pad fasteners (had to find some that would work at the local parts store), those that came with it would not work, installed my hood latch, and refinished my clutch push rod, and worked on the linkage a bit by installing an insert to prevent wear. However, I am having to slowly sand the inside until the clutch pushrod fits into it. Figured I would attach just a few pics from today. I thought about doing away with the ESC Controller and getting an MSD Distributor. Not sure if I should keep stay original or go that way and close off the firewall hole for the wires from the ESC and pull out the controller yet. Any suggestions!

Edit: Went ahead and pulled the ESC back out and may weld in a patch panel where the ESC wire harness comes through the firewall, unless I use it for a CD Ignition Box under the dash. Wish I had thought of it prior to refinishing the firewall, but it is what it is.

Pulled the trigger and ordered the MSD 8362 From Holley. Installed a bushing in my clutch peddle pushrod mounting hole to prevent ware and looseness. Have to get another boot and then will get my linkage reconnected. Should complete my wiring by the end of this weekend and then I have to do a little work on my hood get it installed and then on to my fenders & wheel wells.

Did you land your brake differential pressure switch connector there intentionally?

Put the switch back on the clutch peddle into its original location and the electrical connector for the proportioning valve. Any suggestions of something better will be gladly accepted.

Thanks VZ! Mine must have got bent down and I did not know it. Will bent it back up. Been working on my harness some more today and have it about right. I Have a grey and yellow wire that goes to the (appears to be radio connector) know what the radio connector looks like just not sure if there is a connector prior to it, where these wires go. Will try to track down the other wires to find it tomorrow and the radio wire harness. Will attach a pic (see the Yellow and Grey) the two wires broke off and not contacted to anything. Wiring on the truck is a pain (but getting use to it and not as bad as it was at first) and I was a master aircraft electrician. Problem is the location of some connectors and 4 or wire spliced junctions that has no location and the diagrams in my maintenance book it not the best of quality (hard to read when two diagrams bleed together). I am used to well written and clear schedmatic diagrams. Will use weather pack connectors in places when I am done.

I also have the switch on the transfer case that I have to try and hook up. I installed a new one and a weather pack pig tail to the switch, need to wire it in with no existing wires. I believe the old switch was probably wired up at one time and disconnected and the wires disappeared from someone doing transmission work or such. Now days, I do almost all work on my truck. Will still have to wire in the Vintage Air GenIV unit when I get to that point.

Yellow is accessory power, gray is instrument panel dimmer.
