67-72 Printed Circuit Layout
 

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).

Allright AH619 you may want to ask this question as it's own thread. I'll do the best I can to explain it. I'm going off what was on GMC Pauls page that I linked and some other stuff. But what that referred to was the old style ammeter took full power from the battery and that wire looped around to some kind of junction box and then to the battery. I do not have mine hooked up as that is the circuit that was burned up on the card. Which i'm pretty sure backfed into everything else or it burned up at the same thing everything else did. I'm not sure if that helps but it's what I have figured out from reading other threads and pages. -Jason
