On the US 240sx ther eis a total of 35 wires and on the clip there are a total of 34 I know which wire is the extra wire and that is not my big problem there is a lot of wires that are the same color and I need to know what goes to what if someone has a wiring diagram or something like that or knows what I am talking about and can help me through it that would be great you can message me or call me my numer at the shop is 909-608-0805 I am there from 9-5 mon-sat and i am in california

Thanks

FSM is factory service manual.

It has the necessary diagrams you need to wire up your car.

RHD is okay, i like shifting better with my left hand.

 

i had no clue what you meant at first thanks for you help

 

i did this exact same thing to a friends car... pretty much all the colors match with the two harnesses. We pulled all the seatbelt sh*t to make it easier, just by color matching everything works... except the clock resets when you close the door haha

 

so you could just cut both of them at the end and be able to wire them back up with just the colors? has anyone else done this? does it really work?

 

well were you able to color match?
