Ive got a 2000 nbs tahoe i installed a dei 561t with a 1700g bypass i want the doors to unlock i need to know what wires to hook up .Itll autostart fine hit brake it shuts down toggle switch works.From the 1700g i have the red+,black- the purple to purple data,blue to blue561 status.NOt hooked up on 561 is WHITE/ red ,RED / white, grey/black ,WHITE/ blue ,yellow, GREEN / WHITE , GREEN/ black. and of course the blue and green wires from the door unlock/lock.Also key sense wire violet and black from 1700g should that be going to b9 light green wire at bcm.

ok i think it goes like this GREEN/ black from 1700 to green lock of 561t and blue/black from 1700 to blue of unlock on 561. grey and black will have to go + dome light .Still would need to figure out the green and lgith blue from 1700.ill work on this atlunch and test it.Am i on the right rack.

Other thing the 1700g will unlock and lock the doors on this year tahoe right?Or wil i need something else or wirein relays?

Here is a link to Bulldog Security for the wiring guide: https://www.bulldogsecurity.com/bdnew/vehiclewiringdiagrams.asp Looks like 2000 thru 2002 are the same.

I could not find a install guide for the 1700g to be sure, but I believe it does the door locks for you. However.....

You could wire directly from the 561t to the Tahoe. Use the 561t's blue and green lock/unlock wires connected to relays as per this diagram https://www.the12volt.com/doorlocks/page3.asp#3wp ( the Tahoe has positive door locks ) and then to the Tahoes' wires at the BCM.

Great. posted_image Often times the old school, direct hardwired approach is the best.

Good luck with the SRX.
