    Need help with engine bay wiring

    I purchased the complete engine harness about a year ago, and highly recommend that route if $$ permits. I had to make one modification to get everything working correctly, but it's been working great since.

    Spray in bed liner

    Here is the LineX in my '81. I had it done back in 2000. It needs a good scrubbing, but still looks decent.

    Intermittent wiper module 1981

    Delco D6355A is the p/n for the delay module I installed in my 81 Chevy. I found it on Amazon a while back, not sure how scarce they are now, but so far it has worked flawlessly. It looks a bit different than the original, but plugged up the same.

    Almost no lights after engine harness change.

    All is well in my 81 Silverado! Thanks guys for the help, especially Jabin, that did the trick! Before the harness change if I had my lights on, and A/C on high, I'd barely break 13 volts. Now with everything on, it stays at a solid 14.50 volts, and my voltage gauge no longer twitches. Now I'll...

    Almost no lights after engine harness change.

    Here is a crude sketch on how the alternator and starter are physically wired up right now, and voltage at each location. I have voltage everywhere except from the red wire on the pigtail connector to the 2J connection at the firewall. Suggestions please on how to liven things up at 2J!! I'd...

    Almost no lights after engine harness change.

    The starter had three wires on the large terminal: Positive battery, red to firewall junction, and a light colored wire that was chopped off, live, not hooked to anything, and purple solenoid wire to circuit 6 on bulkhead. On the alternator the batt terminal, and pigtail red wires are spliced...

    Almost no lights after engine harness change.

    I started dissecting my old harness, and found 2,2G and 2C are all tied together. The alternator pigtail used from left to right starting at the largest terminal: 2G, next terminal not used, the blue wire from the oil pressure switch was hooked here, and the brown wire in the fourth terminal.

    Almost no lights after engine harness change.

    Ok here is what I have for voltages. There is only one fusible link on my harness down by the starter. There are three wires hooked to the starter total, the purple solenoid wire, positive battery, and the wire with fusible link that hooks up to junction block. I have 12.22 volts at the starter...

    Almost no lights after engine harness change.

    I'm not sure, I guess that's what color they were making them that day!? I'm concerned about the red wire, why it only has .05 millivolts to the bulkhead, and how to resolve that issue.

    Almost no lights after engine harness change.

    Hey guys, Thanks so much for the suggestions! Here is what I have found this morning after tracing out some wiring. From the plug on top of the alternator, there is a red wire that goes to circuit 2 on the bulkhead upper left side. It has very little power going through it, like 0.05...

    Almost no lights after engine harness change.

    I must have missed that lesson!! Send me the thread please! Funny thing is everything worked as it should before the harness swap, even the choke light. I have no idea how it was hacked to work, but it did, and plan to get back on it this weekend, I want it right.

    Almost no lights after engine harness change.

    No problem! My oil pressure switch came in today, and I have a brass adapter ordered to accept both the oil sender, and switch on the way. Napa said my truck didn't have one, but it is right there on the wiring diagram! It does just what you said. At least that portion of the issue will be solved.

    Almost no lights after engine harness change.

    Hey guys, sorry I haven't been on in a long long time, had a lot of life happen! Anyway, I decided to tackle the engine harness on my 81 Silverado as the old one is all hacked up with butt splices, and lack of fusible link at the starter. I ordered one that is set up for the serpentine...

    Engine wiring harness 1981 Silverado 350v8

    Hey guys been away for a while, and glad to be back! Haven't really had to do any work on my 81 Silverado lately, but now I've got the itch, and the next project I want to tackle is replacing the engine wiring harness as it's a hacked up mess. From what I can tell the original good wiring was...

    Service Parts Identification Decal? (SPID)

    Awesome Jay! I have the original invoice from 7-22-81 that lists all the options I'm guessing the dealership got off the SPID. It cost my Grandfather $10,157.18 brand new! The guy's handwriting wasn't the best, but I made it out the best I could: All weather air I can't make out the second item...

    Ok thanks HotRod, kind of what I was thinking.

    Service Parts Identification Decal? (SPID)

    Due to the 2004 theft of my truck I am missing the "Service Parts Identification" decal for the glove box, also the tire size/inflation information that was below the door striker, and the GM id decal that was about eye level on the inside edge of the drivers door. I remember it being...

    Thanks Stroked, it was like being reunited with an old friend. I seriously thought I'd never see my truck again.

    New from Texas

    Hello, new guy from Texas. I have a 1981 Silverado that's been in the family since new except for when it got stolen in 2004. Thankfully I got it back in late 2007 in one piece, but it has needed a lot of work to get it back to pre stolen greatness. Unfortunately the VIN decal, tire pressure...
