These are pretty basic questions!!!

Im about done the install in my 03 Avalanche and well it says i need 4 relays because i have that Multi-plexxing door lock system.

Im really just trying to figure out how i wire up the relays and do i have to go to each door lock switch to put the relays in.

2)for my door pins do i really need to do a wire from each door back to my alarm or is there a cheater way around this.

Thanks

Why not just get one of the many databus interfaces. The extra cost of one of these is worth saving the headache of running wires into all of the doors.

yes for door pins have to go to all the doors liek the dirageam says. If dotn have the data buss going to have to to do the same for the locks, not hard to do just takes times that is all.

lock/unlock - there's a plug in the bottom of the BCM right behind the airduct. if you take that plug out there's two rows of pin's - a&b, row b only has a few wires at one end, on the oppossite end of the wires you'll find empty slot's 2 and 3. slot 2 will unlock the door's and slot 3 will lock the door's using a negative pulse! pull the blue connector lock in tab off and use a small guage wire (20 or 22 guage) strip about an inch of insulation off and slide the wires through the slots top hole and loop them into the hole's where the pins from the bcm will enter the connector. put the blue tab back on and there you have it. make sure they stay put while sliding the connector back in.

you shouldn't need any relays just make sure that the alarm's lock/unlock outputs are negative.
