Wiring Harness
 

I'm looking for the best wiring harness for my 68 K20. My first instinct was to just get a painless, but my buddy said that they are anything but painless.

AAW American Auto Wire

Re: Wiring Harness
 

I'm currently in the middle of a rewire project on my 71 K10. I went with the classic update kit from American Auto Wire. I've never done a job like this before now and I will say that it took some time for me to get used to it. I wouldn't say the directions are crystal clear or step by step. They leave a lot up to you since there's variation in the trucks. I will say that AAW has been great when I call so you have that to fall back on. I read some advice on here to take your time and have patience. That's good advice. I spend as much time figuring out things as actually doing things. I can't say how aaw compares to others, but I think quality is good. My question would be about how the instructions compare.

If I did this project again, I'd be much faster the 2nd time. I've learned a lot so far.

love my aaw classic update harness. the connectors they use are durable but i suggest getting the proper crimp tool for them. i also soldered all the connections and sealed the plugs with silicon for a water tight connection. no more electrial gremlins and its really clean. the wires were extra long making it nice for my longhorn.

What kind of harness are in the market for? A plug and play stock replacement? A full on custom to go with an LS and 8L90 installation? Or something in the middle?

Great question.

If you have a stock truck, then stock is the way to go. If you have a heavily modified one, then a Painless (or similar) may be OK. Just do yourself a favor and throw away all the cheap crimp connections and solder the right ones on. You will likely need some factory type terminals (a lot of "type 56").
