Need help with the wiring portion. I brought back a auto FD from Japan, I only got an auto because I got early orders back and I had to sell my manual (it was too new) and got a really good deal on a low mileage auto (and I wanted a sunroof!). I’ve already swapped the rear diff, driveshaft, transmission, installed the pedals, and shift ****. What I read on the forms for the wiring was conflicting and most of it was for USDM. I’ve tried bridging the connectors on the gray connector (2 biggest wires) and no luck. Has anyone successfully swapped a JDM car and what did they do for wiring? Please help. Thanks.
