GM under Dash unit - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I bought this unit out of a 68 Impala a few months ago. I took it out myself and brought it home and started tearing it a part to clean it up and refurbish it. I have it all done now it's back together and just wondering if anybody has any info on it. I think it's pretty simple wiring with just a 12 volt + and negative wire. But I would love to get a copy of the instruction manual like I found on E bay for it.
If anybody has any info I'd appreciate it are know where to look for some.

Well I found some info on it. It should be enough to get it hooked up and running when I get it installed.
Found this on a 67 Impala site. Guy suppose to be getting me some pictures of the manual also he said if he can find it.
