first, the car is a 2006 chevy equinox

remote start is avital 4103 with idatalink tbsl-pl module

what i need is someone to explain to me what i need to do operate the locks with the avital key fob. i know the car is +lock/unlock and the brain is - polarity. what type of lock system is in this car, the 5 wire or reverse polarity type?

The door lock and unlock wires are at the 16 pin gray connector of the BCM, below the radio. Pin A2 is a light blue wire (lock) and pin A3 is white (unlock) They need a positive pulse to activate. You need 2 relays (one for lock and one for unlock)to convert the negative output from the remote starter to a positive pulse. See the relay diagram link on the left side of this website on the wiring to convert a negative pulse to a positive one (polarity change).

ok so i just follow the reverse polarity diagram, got it.

what wires are you refering to? according to the wiring diagram

Power Lock lt. blue + BCM, pink plug, pin B4

Notes: The BCM is located in the center console, below the radio.
Power Unlock dk. blue + BCM, 24 pin gray plug, pin A3

if i got it right , thelock and unlock wires at the bcm connect to 30 on the relays and the lock unlock wires from the remote start connect to 86 and 85?

Two relays required:-
5 amp fuse green and blue from alarm to 85 on each.
Constant power on each 5 amps fused to 86 and 87.
You got the rest right.
Or a 451 relay module from DEI, plugs straight in to lock socket on Viper.

Because that's a motor interrupt.
Look AGAIN at my post for the wiring, if you have 5 pin relays ignore 87a. Bet you're looking at the 5 wire install diagram, that reverses the motor wires you're simply reversing polarity, BEG to POS.
Relay 1
Blue from Viper to 85
86 AND 87 to 12V+ constant fused at 5 amps.
Share with relay 2
30 relay 1 to dark blue + BCM, 24 pin grey plug, pin A3
Relay to Green from Viper to 85
86 and 87 see above.
30 to light blue + BCM, pink plug, pin B4
