I have an '84. I am putting a V6 in it. I know, not very exciting compared to some of the other swaps that have been done.
I would like to see some pictures of the wiring locations particularly the area behind the battery where the connector is mounted. Apparently, I need to relocate the C500 to the side from its current location in the center of the firewall. Seems like a good idea with the proximity of the V6 engine heat to the current location of the connector.
It might help to post a picture of what you have now that you think needs to be relocated. There must be some existing posts in the Archives with lots of pictures for the 4-cylinder to 6-cylinder swap.
