i never really found a write up or anything... but its commen sense kinda, i helped a buddy do it before basically all you gotta is extend wires, rewrap them in the plastic wire lume, then just run them under the wheel well fenderliner and/or through your fire wall... you just gotta be careful with the wires and connecting them coreectly. if you do this i reccomend getting a beater car to drive around
