And yes, to whoever said their customer service is good, I second that. I called them a bunch of time and they never were at a loss for assistance. AAW to me, is a solid product with great customer service.

I have installed two AAW kits -- a Classic Update kit in a 66 C10, and a universal kit in an 82 C10. Also used a universal kit from EZ Wire to do a friend's 37 Chevy car, and a Ron Francis universal kit in a 55 Chevy car. Just remembered I also did an AAW engine harness kit in a 64 Impala.

I'd rate both AAW and Ron Francis very high, however the RF kits don't use a bulkhead connector, but instead run wires through the firewall. On the other hand, AAW uses GM replica bulkhead connectors in their Classic Update kits. Some people like the RF kit because there are fewer connections to fail, but it would be a pain if you ever needed to remove the front clip.

Both have very good instructions and tech support, but I think AAW is a little better in both categories. And both are light years better than EZ Wire's poor instructions and arrogant tech support. The only nice thing I can say about them is they used good quality GXL wires with thicker high temp "cross-linked" insulation, as do AAW and RF.

I haven't use Painless, but I have used their 132 page(!) manual for their 73-87 pickup kit to get information I couldn't find anywhere else. I suspect their products are also first rate.
