im installing a remote start/keyless entry in my 98 and my wiring diagram is saying to tie into the tan, orange and dark blue/white wires for the door triggers but i know i can just use the white all door trigger, cause lets be honest, one wire is easier than T'ing and isolating three wires, however idk which color plug and what pin number the white door trigger wire is on the plug and was hoping someone could be of some help on that.

i'd just wire it up with your dome light being the door trigger. if your really serious on being "secure" you'll want to isolate each door seperatly. cause in theory if someone broke into your truck and removed all the map lights and the dome lights the alarm would possibly shut off. thats why they isolate each door seperatly. if your not too worried i'd just tie into the white wire. which if i remember correctly if you take a ground to it your dome light will light up. that way you know for sure it is in fact the correct wire
