I have two 87 740s, one turbo and one is not. Due to rust issues, I'm thinking about putting the N/A motor (147,000 miles) into the turbo car.
The battery and air mass meter are on opposite sides of the cars, but the big problem I see is the wiring harness. The turbo car has 2 main harness connectors at the firewall (1 on each side). The motor and harness from the N/A car has 3 main firewall plugs, 2 on passenger side, one on drivers side.
It looks like I can make the harness on drivers side work, with a change on 3 wires. The bigger problem looks to be on passenger side.
I see that I could change the harness through the firewall to the computer fairly easy. However, part of that harness also goes to the speedometer and who knows what else?? Fuse box I suppose.
The computers are also different ##.

Thanks in advance for your comments.
