Pulling All Wiring

Team:

I am at the stage to pull my wiring from the truck. I plan on buying the AAW kit, but before I do that, I would like to pull my wiring as completely as possible to check out if its salvageable.

Is there any logic to pulling the wiring as a whole? Or should I even bother trying to pull and salvage it?

I am just trying to possibly save a couple hundred bucks if possible.

Re: Pulling All Wiring

I removed mine part by part, front head light , engine, under dash part was hardest to figure out but not to bad. Rear loom runs along driver side frame is easy. My under dash loom was cut up so bad I will be replacing the whole harness.

Re: Pulling All Wiring

The underhood harness is two piece at the square connector block/fuse block. Depending on options you might have some extra wires(like tach). Unplug wires at fuse block under dash remove them separately then remove fuse block and attached harness.

Re: Pulling All Wiring

IMHO unless you have a lot of custom stuff, you are way ahead to keep stock harnesses. To do an aftermarket harness right takes a lot of time. You need to solder and shrink and find correct terminals and shells then route and wrap. If you just butt splice old pigtails to new wires you are no better off than a hacked up original. I would just pony up for new factory style harnesses, take half a day to put them in and ride. To do an aftermarket harness right will take a few days work and some chasing connector parts.

Re: Pulling All Wiring

When freshened up my truck last year and prepared it for paint I removed the factory harness. The rear pig tail & the under dash harness was totally hacked up. I was surprised anything worked, well there were a few problems but......The parts of the harness that not hacked up were very brittle with some items falling apart as I removed it.

I purchased the AAW classic upgrade kit, with provisions for internally regulated alternator and HEI, it was a total kit will everything provided, except the crimpers. The harness and the instructions were top notch and the kit was easy to install.

Re: Pulling All Wiring

I'll be ordering a complete set up from M&H soon, there won't be an old wire in the truck. I have way too much time and money into my truck to take a chance of some old brittle wires shorting out and burning my truck to the ground. M&H makes harnesses just like the originals, plug & play. They also make a few mods for things like, HEI, internally reg. alt.

Re: Pulling All Wiring

If you have more money than time I would get an aftermarket, complete harness and plug-n-play.
If you're like me and tend to have more time than money I would rebuild what you got.
Its easy to do. Pull a complete harness. Most of the little brass connectors inside the plastic connectors are "Packard Type 56" connectors. NAPA part number 725147 is the female connector of which most of your connections will need.
The wire can be had at Menards/Lows/Home Depot. Stick to replacing wire with the same color so in the future you know what you are looking at when you are chasing a problem.

I keep those little type 56 connectors on hand because I own three vehicles from this vintage. Any time I have a problem I just fix it right the first time.

I should add the male type 56 connector in your truck is NAPA part number 725145.

Just what I have started to do, outside the fact my front clip is off already.

If AAW wasn't around, I would think twice about doing what I am about to do.

Have you done an install with AAW? Would you feel safe removing every wire, knowing the AAW would have you covered?

What crimpers did you end up buying? I have read this is the one area to get a decent set. Let me know, thanks.

Yeah, I am glad I have read up on AAW because I know I gotta decide what alternator I will be running before I place my order, correct?

Great post! Thanks for the input. Do you happen to have any pictures of your process? Have you rewired a truck all at once using this method?

I bought both sizes from AAW, they are both needed.

No. However I bought a used AC wiring harness when I converted to a stock AC setup and rebuilt it before I installed it. The connector behind the fan speed switch was melted. When I looked at other AC trucks in the yards I noticed they are all melted. Because of that I orded a new plastic connector from a supplier - I think I used LMC at that time - and a new switch. I then simply rebuilt it all and never looked back.

I've never experienced problems with old, unhacked wire so I only fix/replace what is messed up.

Re: Pulling All Wiring

Yes the AAW wire harness. I really like them a lot. Fit great and look nice. Wouldn't buy any other brand.

Re: Pulling All Wiring

Yeah there are about 4 different alt plugs, so you'll need to know witch your using. When I spoke to M&H they said I'd also need to know what side of the motor the alt will be on so they have the correct layout and wire length.

This is all the wiring from the firewall and throughout the engine bay. The AAW kite will come with all this, correct? (as I bite my nails)

Yes if you bought the front harness for the lights and the one for the starter etc, it will come with the ends to plug in the fuse panel on the fire wall all the way to the areas you need to go to. Post it up when you get it back together or if you need some help

Re: Pulling All Wiring

In this for the long haul, I am about to do the exact same thing with an AAW setup as soon as I can afford it. I would think there are a ton of us out here that would love for you to take pics all through the way to help us as well if you could. If there is anyway way we could help I know I sure would. Thanks in avance for any help along your way!!

I plan on doing write up for sure, but this project won't be happening until about February/March. Keep your eye out.
