I don't have a ton of progress to update because unfortunately I hit a snag with the wiring. I obtained two dash harnesses, one from a board member out of a '77 and the other locally that was supposed to be from a '76. The '77 it turns out is quite a bit different and it had some cuts and splices. The '76 harness looked identical and was completely uncut, had all the same connectors, and looked plug and play but after I installed it I had no power. After some investigation I determined that it was actually a '75 harness and the harness is pinned different between '75 and '76. I can make the engine harness match, but it's going to be a chore.
I did get the tires and rally wheels mounted, and did a quickie resto on the gauge cluster. Plus I installed Cerwin Vega 6x9 speakers in new cab corner brackets and a new Retrosound 4x6 dual voice coil speaker in the dash. I found a decent original seat under that cover except a small tear and decent carpet. I also bought some sport mirrors, new sill plates, and door seals. I can't wait to get the electrical sorted and driving again, but this is definitely not my favorite work. It does make me feel good to make everything "work" like it should. |

Wiring sucks.

"New" shoes = original rally wheels powder coated, new tires, new center caps, new rally rings. Doesn't get much fresher!
When I look at her though all I see is a lowered short bed with sport mirrors. I'm thinking after that some woodgrain on the cream paint like YG2 option? |
Re: "Root Beer Float" 1976 Scottsdale
Looking good. I vote you leave the mirrors as-is but that's just me.

Re: "Root Beer Float" 1976 Scottsdale
Did you get the wiring figured out?

Any advice on the male connectors? |
Re: "Root Beer Float" 1976 Scottsdale
Make sure you have the fusible links to protect the harness.
I would be looking for a good used harness rather then trying to build my own. |

Well I got the engine harness re-pinned and repaired with some new packard 56 connectors. Then it wouldn't fire, and I chased my tail for way too long. First I found a difference in the neutral safety connector from 75 t0 76, so I swapped them out but it still wouldn't fire. I isolated the problem to the ignition switch and found the ignition rod out of adjustment. :dohh: I also had to buy a new printed circuit because mine couldn't be saved.
I REALLY do not enjoy this kind of work, I'd rather spend time on things that make them look and drive better. Oh well, some tidy-up and interior re-assembly and we'll be driving it again. |
Re: "Root Beer Float" 1976 Scottsdale
Leevon, nice job on the re-wire... I am doing a LS swap with trying to use the '13 OG harness & fuse box!! so I UNDERSTAND how wiring is not enjoying... :lol:! I Like the large scale printout of the schematic, curious as how you did it & still made it readable :ito:? I tried to do that, but it always comes out unreadable...:waah:
nice job! |

What year is your truck? |
Re: "Root Beer Float" 1976 Scottsdale
How is the retrosound 4x6 dual voice coil speaker? If I understand correctly the onld speakers were mono. This speaker provides a stereo output.
Did the speaker use the factory holes? Also I thought the front speaker in the middle of the dash is 4x10. |

Re: "Root Beer Float" 1976 Scottsdale
Leevon, I am doing a LS swap in a 1986 C10 SWB and a 2013 4.8 silverado drivetrain. I do have a build page in this section - if interested :ito:. I am just about ready to fire it up. I need to be able to clear the codes & check some wiring issues. The diagram I was trying to plot was from the '86 diagrams...not soo good of quality :ito:, unlike the 2013 diagrams. those I could see printing in good clarity ;).
keep up the updates!;) |
Re: "Root Beer Float" 1976 Scottsdale
I don't know if you want opinions on this, but I think that's a very cool color combination and I hope you'll consider leaving it as a sporty long bed truck. It's a great looking truck and you are getting all the bugs worked out. It does look like the back of it could come down a few inches, but I would say, level it out, and let 'er rip.

Re: "Root Beer Float" 1976 Scottsdale
Too bad you weren't up here, I've done 2 full rewires and have a bunch of those blades.

Got the re-wire done. I put the interior back together with a bluetooth stereo and new dual channel center speaker and of course the seatbelts restored by TKCR. It's not much to look at but now everything works and it's probably not going to burn to the ground. I decided just to run the seat without a cover, it had a split that I temp patched (ugly I know) but it's functional. If the truck progresses to paint with me I'll re-do the interior completely.
I also changed the coolant temp sensor, the one that was installed in the '91 TBI 350 in the truck was the wrong resistance. And I removed a crap job done on the 700R4 lockup. There was vacuum switch (right idea but poorly executed). That also fixed a vacuum leak and now the trans locks up directly in 4th gear. It will bog a little on hills, but some gas will downshift it to third no problem. It drives way better than it did before, constantly going in and out of lockup. After all that I'm finally comfortable driving the truck around. I put about 100 miles on it this week and it starts, chokes/idles and runs great. I got her up to about 80mph and it tracks straight and is quiet enough. |
Re: "Root Beer Float" 1976 Scottsdale
Next up:
1) Brakes 2) Door seals and sill plates 3) sport mirrors 4) SHORTBED |
Re: "Root Beer Float" 1976 Scottsdale
Great job on everything.
Looking forward to the short bed conversion. |
Re: "Root Beer Float" 1976 Scottsdale
Lookin good!

DISAPPOINTMENT ALERT:
I sold Root Beer Float. It was really nice to drive after I had the bugs worked out and cruised at 80mph no problem. But It shipped out to Phoenix last week, from there to LA then on it's way to Australia. But I bought a cleaner/cooler/better truck, a '79 GMC k15 400/350/np203. Look for the new thread! |
Re: "Root Beer Float" 1976 Scottsdale
Congrats on the sale!
Nice looking k10. |
