I'm not sure if this will help anyone. But, I have been trying to figure out all of the mess in the wire loom that is the connector for the guage display so I could adapt it to my new American Autowire fuse panel. The info I had with the stuff I found out GMC Pauls website, (yall should check out his page it has the other wire loom layout), finally helped me put this together.

I'm not to smart so I made this so I could print it out and have it all on one page. If it helps someone cool. I think it came out allright I had to sample it at a lower rate to get it to post. Thanks to all of you that have been helping me. -Jason
Allright I can't get this any bigger. I guess because of the limit on pixel width.
If you need the big one PM me it's like 3 mb's (ok it's not three meg's but still to big to fit).
