FAQ: GTR Wiring Harness Setup for 94-95 B6 MX-3

Post by MechaManZero »

First you need to get the harness extended. Than when you get it through the firewall if you have the JDM Harness you are going to need to switch around two plugs by cutting and splicing the wires to the MX-3s 3 Plugs. This is using the Europeans Harness diagram but the JDM one has the same wiring color.

323 GTR Europe (Same as the JDM wire Colors)

Sorry about some of the missing wires not totally complete with the total conversion.

Sorry I left out any ABS or Air Bags. I didn't get to that cause I didn't need them. The A\C is there incase you want to use it. :) Happy swapping.

Its almost the same for the SOHC 1.6 you need to cut all 3 mx3 plugs and mate them to the GTX harness.
