Nope the purple wire goes to the gauge cluster and the black/white wire is grounded on the firewall and seems to be a good ground but i'll move it around tomorrow and see what happens.
My biggest concern now is the transmission. I've seen manual trans. trucks roll off while parked but never one with an automatic.
Can the tachometer signal be changed in the tune or will I need a converter? if a converter is needed is this what I need?
