Which AAW kit did you get? And other than the Covan dash and gauges, is everything pretty much stock?

AAW provides some great schematics. Even if he has to deviate a little, just make sure he notes the changes on the schematics. Then scan the schematics to PDF and save them. If you're staying pretty well stock, it's not rocket science. It just takes patience and attention to detail.

One caution - not a big deal. The AAW stuff is excellent stuff. I used a highway 15 and am very pleased with what I got, though I heavily modified it. However, the printing on the wires can be removed with "Goof-Off" or other similar "adhesive and gunk removers". I wanted to remove some printing because of modifications so I tried and it worked. I'd hate to see somebody do it by accident.
