Anyone know if you have to use a relay for the door locks?
Thanks.

My chart shows positive at lt blue and white at module below steering column. Ultra's have negative outputs only.

positive three wire pulse? huh?
It is a single positive pulse lock is light blue and unlock is white at brown plug at bcm or behind driver side fuse panel cover
12 volts - red ignition harness
ignition - pink ignition harness
2 ign - white ignition harness
starter - yellow ignition harness
acc - orange ignition harness
2 acc - brown ignition harness
park lights (-) white @ blue plug at bcm
park lights (+) brown @ blue plug at bcm or behind driver fuse panel cover
door triggers - Use tan for the drivers door located in pin B4 of the purple plug, and for the passenger door it will be a orange in pin B2 in the purple plug or dk.blue/white in pin B11 of the lt.blue plug, must diode isolate these wires. The BCM is located behind the drivers side of the dash. The plugs on the BCM face towards the rear of the vehicle.
domelight (-) white @ underdash light or behind driver fuse panel cover
factory alarm disarm (-) green @ driver kick or purple plug at bcm
horn - black brown @ plug at bcm

you know five wire reverse pulse refers to the wires used to wire a relay as to three wire posi trig for relays not refering to amount of wires u need to find in vehicle that is as i said if your outputs are neg of the brain

Need to wire a relay for anti-grind and domelight, but every resource I check on the 'Net shows a different way to wire relays. Is there one correct way to wire a relay for each item?
