While I didn't initially purchase my car to have to do an entire rebuild, it almost feels like I have. New front end, new brakes, rebuilt radiator, gas tank, steering, rear end, bunch of other stuff.

I actually have the wiring set from American Autowire, as it needs the wiring replaced. Problem is, I might have to pay someone to do it.

Has anyone replaced all the wiring in a fullsize? Did you have to remove everything, like seats, dash, etc.

I have some mobility issues due to my back and other military disabilities, so if I can do it, it would save me a ton. But if it is a ton of work, it might be best to have someone else do it.

I know I haven't been active on here for a while, my apologies for that. Just had life throw us a few curve balls. Lost my mother in law and sister at the end of 2018, had grandkids move in with us May of that year. I don't want to even talk about 2020.

Thanks for any info guys/gals

Hi Mike, I just did the American Auto Wire under dash, on my 66 and have the firewall forward engine harness on order.
Not sure what harness you are going to tackle, but if it's the under dash and you have back issues remove the front seat(s). My back is trashed too and it made it a lot easier. Plan on using the entire day, then you can surprise everyone and do it in about 4-5 hours.
The ribbon cable that goes from under dash to rear harness of course will require the removal of at least the drivers seat and the rear seats.
Under hood stuff is fairly easy with just a little contorting around. And the rear lights one is also straight forward.

That's exactly why I sold my Mustang today after 39 years of ownership.
I can add needs engine and transmission rebuild and paint to your list.
Anyway good advice from Steve, and for 65 don't forget to disconnect the copper oil pressure gauge line from behind before you pull the dash.
It's not forgiving to yank on like a speedo cable is if you forget to disconnect.

Thanks, I purchased the entire kit, was like $850. I do have some back problems, so I appreciate the advice. Some of the wiring was literally stiff when I first purchased the car.

First thing I did was take it to a mechanic to do basic stuff, oil, tires, plugs, etc. I had them put a new coil on and when I was talking to them about it I also said the thermostat and the wire was stiff so I said, replace that too.

Well, they replaced the coil wire, but not the coil as I asked, and they didn't do either to the thermostat nor the wire.

I drove it right after I got it and it died. After towing it back to their shop I called the owner and he came to the shop, tried to start it. When that didn't work he looked in side and I noticed the coil looked like the old one. So I mentioned it. He ran inside and got a new one, put it in place, replaced the wire for the thermostat and it started working.

The old wire to the coil wasn't able to give the old one a full 12v, due to the degradation of the wire and increase resistance. So when they put the new wire, but not coil, the old coil started getting 12v, which made it last only like 30 minutes before it burned up.

I have noticed other issues, improper grounds, etc and it has been a pain. I have a new instrument panel for it as well, which I know will require the dash, or parts of it out. Even though I have an electronics background, I would prefer not to make things worse and have to pay someone to fix my mistakes. Plus if I start replacing the harnesses and have to stop, I will have to tow it to a shop for them to work on.

I appreciate the input.

Thanks.

Reminds me of a incident in the mid-1990s when I worked for the gov and we had just performed a reorganization over the weekend. On Monday a guy got to his cube and didn't like where the computer was, so he started to move it. It got harder to move the further he attempted. The guy in the cube next to him noticed his computer was moving while the guy was pulling.

Back then we used coax cable with the computers hooked up serially, so as he pulled his computer, which was connected to the one in the next cube, it start moving it. He pulled so hard he broke the cable, and everyone on that line went down.

We had to take a tester which would tell us about how many feet the break was. As we were looking around, he didn't bother to pipe up letting us know what he had done. After we found it and fixed it we told him not to move his computer again.

He was about as bright as those folks that would take their emergency floppy boot disk and use a magnet to secure it to their file cabinet as we told them, "don't lose this". Idiots everywhere.

I just installed a "classic update" kit from AAW in my 65. I have never really messed with wiring and was somewhat intimidated by the box of wires. I removed all the seats and the dash, this made it way easier, luckily I am in good physical shape. Just removing the dash will make things much easier and I didn't think that was a huge process. If you are installing a "reproduction" harness it might be easier than the update kit. The instructions were 99% good and I am happy with the outcome (everything works).

Cool, I may search deep in my being for the courage to do this then. I would rather spend the money on paint and interior replacement than someone just putting wiring in if I can do that.

Hey Mike, I put a Classic Update kit in my '66 a couple years ago. Lots of extras, you won't lack for extra wires to hook up any upgrades you want. One thing I thought you should know if you got the Classic upgrade you will get a fuse box and fuses which are the newer style. And the firewall will have to be cut just a bit. I used a cheap 1/4" air saw that I've had for years. It's not very powerful but it did cut the opening good. But you may want to pull the booster if you have PWR brakes.

Thanks, I didn't get the classical kit, I got the upgraded one so I figured there was some cutting.

I looked all over YouTube for a vid on it, but couldn't find one. I found them for other cars, but not Chevy fullsize 65, or years close to that.

I really want to drive my car more, but have to get this thing done.

One thing to be aware of on the "classic update" kit is that almost none of the harness is wrapped. I probably spent as much or more time getting the wiring to look good as I did on getting it installed correctly. I'm not sure if what you have is wrapped from AAW but that is something to consider.

I like the sounds of that! I'm getting my 66 painted, probably today, and I'm going to put in the AAW kit I got over the winter. I did my 55 by myself, but if there's a chance I'll ruin something, it takes me that much longer to get started on it! Seats are already out of it, and I skimmed over the video on pulling the dash (will watch completely later) and hopefully it goes well.

Stock wiring is easy for me to do. I can have all the stock wiring out in about 30 min including the underhood headlight and engine harness. Last one I did took 27 min. Car had no motor so it saved a couple minutes. Car had full interior and stock radio. Takes same amount of time to put it back in.
