american autowire upgrade kit

hope all is well in chevelle land, currently in process of getting my chevelle completed and back on the road after 20 years. have a question for everyone on the board. chevelle has been parked since 1997 or so, currently going through and upgrading and making whole again, i can go one of 2 way with stuff, change the engine harness and go M&H which would be the easier, or i can go with the aAAW classic upgrade which will add more time and expense. for those that have done it, is it worth it, or will stock wiring from the firewall/dash back be ok and just upgrade the front end area. thanks for the help, this board is phenomanal.

Re: american autowire upgrade kit

I got rid of every millimeter of nearly 50 year old wiring from my 70 El Camino. That stuff had cracked, crumbly insulation that would have leaked all the smoke out almost immediately.

I'm currently installing an AAW Classic Update kit but I have a PSI wiring harness for my LS engine. I have the AAW engine kit but I'm not using it. There's also a lot of wires not being used with my Dakota Digital HDX gauges.

All in all, I'm happy with the AAW kit so far but I'm struggling with no drivers side rear turn signals or flashers. My two hours of play time tonight with wiring at the front of my EC should tell me a lot about these two problems.

Re: american autowire upgrade kit

I used the upgrade kit from AAW in my 70. The quality of the kit, instructions and customer support was great. It is probably more work to install the upgrade kit than the factory replacement harness but I think it is worth it because you get more circuits and you get the more modern type of plastic fuses.
I also installed a Dakota Digital dash and a Vintage Air A/C system, having extra circuits helped.

Re: american autowire upgrade kit

I installed the AAW kit in my nova. I went with the classic because of the extra circuits, which i'm glad i did. Very nice and easy to follow instructions. One thing I would do is buy their crimping tools as they are made for their terminal ends,

Re: american autowire upgrade kit

My '70 Camino had to go to AAW classic upgrade after the harness caught on fire after all those years of being hacked. Glad I did it.

I will second what Slim said about buying the crimping tools for the connectors. AAW sells them and so does Summit Racing. You really need them to make good connections.

How difficult was it to make the crimps with the AAW tool? I'm in the market for a new harness for my 68 Chevelle project and I've heard it is somewhat of a delicate procedure with little margin for error.

I disagree about buying their crimpers. Below is a much better set that will do way more types of crimps than the AAW crimpers and can be had for half the cost. The AAW classic update kit is very good.

Or this set is even better. I have this set and did the entire update kit with it plus have used it for other projects.

Re: american autowire upgrade kit

I'm doing a complete rewire with the AAW upgrade kit for a couple of reasons-
1- 50 year old wiring that was barely capable when it was new is now toast (pun intended)
2- I am adding A/C, big cooling fans, big fuel pump, fuel injection... so I want the ability to add circuits with relays and not worry about the loads.
3- The crimper issue is covered because I have the weatherpac and factory style crimpers.
4- Like the saying goes- how do you eat an elephant? One bite at a time. Just pick away at it and have fun doing it... yeah, ok...

It is not difficult to make crimps with AAW crimpers once you know how. AAW has an instructural video on their website, it is also on You Tube. They give you some extra connectors to practice on.

Re: american autowire upgrade kit

Congratulations on your project to get back on the road!!! All the previous comments are right. 50 year old wire is not good. I just started installing an AAW kit in my '65 El Camino. Its a high quality kit. After inspecting the original wiring, I was surprised the thing hadn't burned to the ground years ago. Besides, the extra circuits will support electric fans, fuel pump, etc. Good luck.

Re: american autowire upgrade kit

Boy oh boy. I changed every wiring harness in my 68 with M&H. After 50 years they are total junk IMO. I also had M&H change my engine harness to HEI so they will make some changes for you. I have gauges and AC. A separate AC harness works off the horn relay to get power back to the AC unit. 68 is a one off kind a car and the AC wiring shows it. M&H does give a discount if you buy the whole setup and I am very happy I didn't try and do it on my own and I have an electronic background. The wiring diagrams in the assembly manual are almost useless with gauges although I have been told much better diagrams are available. If I was going to use the factory dash and gauges its a no brainer to go the plug and play way. If you need extra circuits for fans, stereo's etc. I would add a sub panel in addition to the factory stuff. It might cost another 500 bucks but in my opinion well worth it to me.
