2002 Dodge Ram 1500 Quad Cab Remote Start Issues

no you dont need to do blue or BLACK/ white, just if you want to have the radio and windows work  on remote start but not necesary. just personal preference. i never hook it up for my dealers i tell them its  not critical for the vehicle that when the customer gets in and turns the key on the radio and windows will work. and they wont pay for the extra relays and labor. if you remote start then your outside hence no reason for the radio.

do you know which wires control the heater and the ac? Thanks
