Just needing clarification, when I read "5wi" on the door lock on the 2004 Tahoe, it does mean that it is a 5 wire alternating system??

If you are doing ANY KIND of remote start or aftermaket security....you dont want to do the locks without an override module....like the DEI 456G, or 457G.

Otherwise you have to get into each door with 2 relays.....it SUCKS BIG.

Are you doing something like this?

Yes, i am doing something like that. I never have used override modules anything other than the security bypass, but i havent ran across 5wi lock system either. my alarm dealer doesnt carry any DEI products, mostly just omega and dont have time on this to wait for shipping. Thanks for the info!

Find someone who can sell ya the modules.....it WILL make your life simple.

How they work is, they "talk" to the BCM, thru the OBDII connector under the dash.

If you cant get one of these(check crimestopper, www.bypasskit.com .....) then the relay headache is the only way.

Thats when the "5wire" thing comes in to play
