I did a 83 Celica EFI swap into my 81 and things just aint right. I have WAAAYY to many wires that i dont need but everything is tied into eachother. So, im hoping that a truck harness (which has less wires) would help me solve my problem of "rat nests wiring" under my dash and stuff. Thanx. Im located in Dublin/San Ramon, CA 94568/94583.
