Ramcharger Help

Ok I have tried to sign u with ramchargercentral.com for a month now and have no luck with them.

I will be asking a few questions here and there about random issues.

First issue is I have found a large connector under my dash and it is just rotted to hell. The problem is that there are not enough of the connector left to find a part number on it and my book doesn't even acknowledge it in the diagrams.

Can someone please help with either identifying it or possibly have one for sale.

Second question is that the 318 in it is absolute crap and I have a rebuilt 318 with less than 40k miles on it. The donor engine is in a 76 van. I'm wanting to do the transplant from to the other. I know there are less wires needed for the older motor, and the current harness on the truck is ate up from field rats. I'm going to use a universal wire harness. Would all of the vacuum control stuff still work and can anyone direct me to a website that sells the appropriate wire connectors to hook up the harness to the factory mopar sensors, lights, etc.
