k 9 eclipse door lock wires

I am installing a K9 Eclipse alarm into a 2002 Chevy Avalanche and am confused about the door locks. The alarm comes with a 6 pin connector designated for the door locks and the manual reads: Violet: Unlock relay input Pin #87 (N/O) Blue: Unlock Relay Output pin #30 (Common) Brown: Unlock Relay Input Pin #87A (N/C) Violet/Blk: (Lock Relay Input Pin #87 (N/O) GREEN/ Blk: (Lock Relay Output pin #30 (Common) WHITE/ Blk: (Lock Relay Input Pin # 87A (N/C) My question is do I really need to make a relay for the door locks or can I just hook up 1 wire to Lock and 1 wire to Unlock? And if 1 wire only is needed which one do I connect? The outputs? There was already an aftermarket alarm installed but it was old and didn't come with the remotes... hence why it needs a new one... And it only had 2 door lock outputs that went one to the Lock and one to Unlock. The lock wires on the vehicle are positive. If anyone could help it would be much appreciated. -Thank you-

The locks on the 2002 Avalanche are Type A (+).  The internal relays are prefect for thatapplication.  Connect both Violet and Violet/Black to +12v through a 15A fuse.  Connect the GREEN/ Black lock wire to  the LT. BLUE wire  @ BCM, BROWN PLUG, PIN A4.  Connect the Blue unlock wire to the WHITE @ BCM, BROWN PLUG, PIN A3.  The Brown and WHITE/ Black are not used and should be insulated.Soldering is fun!

Awesome... Thank you so much for your help. Alarm is in and works like a champ!

Good job!  Soldering is fun!
