i have a automatic 1j harness and im using my stock 5spd tranny. there are 2 extra wires on the harness for the a/t. does anyone know what do i do with them? do i just leave it there and not plug it in? will i throw any codes by not pluggin them in? will the car run fine w/o using those 2 extra plugs?

i'm thinking those two plugs are to tell the ecu when its in park, neutral, reverse, Drive, D1,D2,D3 and over drive

thats how its was on a auto 240sx i swapped to 5 speed...two plugs left over, but because it was a convertible i had to connect two main wires from the two plugs to trick it into thinking it was always in park so the top would go up and down..it Was a safty feature so u dont drop the top while driving..

So you should be fine with 'em un-plugged...try it and see what happens..lol, i doubt it will ruin anything, more like just throw a code.
