hi there. i'm thinking of putting a four stage box in to replace the blown three stage but have been told i'll have to replace the whole wiring loom to do it... is that right??
Car is a 3.9l, 1989 fairmont. is on LPG. I was thinking of replacing the motor as well as it's getting a bit tired and a friend has a 4litre motor and an XR6 box with computer he'll do a deal on.. but with little $ at the moment am thinking i'll just stick to the box for now..
just want to suss this wiring loom stuff though! sounds a pain in the bum!
any advice would be awesome!
