okay I found one problem. Near the transmission the round plug with 7 contacts. It had 3 wires melted together one black two brown. One of the brown is from 5C. Fixed that. Now I get now grounded contacts at the relays if the transmission is unplugged. If I plug in the transmission the relays find ground on pin 85 again. What does this connector plug into on the transmission?

Okay so this is definetly the problem area. I was getting ground before with the transmission uplugged because these wire were melted together. Now I get now ground and continuity between all the wires at the relays and the transmission and the fuse box. When I plug this connector to the transmission everything grounds out. So now I just need to know what this is and how to fix it.

Sorry this has nothing to do with the tread but, where did you get that hood. I love it.

Okay so this gray round connector on the top, front side of the of the transmission is very loose. I can turn it about 25 degrees left to right and it pulls in and out just a bit. This is where I am getting my circuit grounded when I plug this connector in. I tried plugging it in then moving the connector around and no change. I have attached a picture. Anyone know what this is?

That'* nothing but the transmission connector that tells it everything.

I'd fix those wires and give it a check with a fuse. What'* one more..lol

It being able to twist is ok. You shouldn't be able to pull it out at all. Here'* what it looks like on the inside. The connector is in the upper right hand corner.

Okay so I tried another fuse. I left the transmission unplugged and started the car. Fuse did not pop car is in limp mode. Turned off car plugged in transmission started car and fuse popped immediately. I am thinking maybe the wires inside are grounding out. A few days ago before I started messing with the wiring and the plugs a fuse would last for a minute before popping without the fans on. Now it pops immediately. I am thinking I have a connector grounded out right at that plug in the transmission. Any thoughts? anyone have a schematic for the transmission wiring?
