Most likely, the locks would probably be like the other new GMs.......Lucerne, Tahoe, etcetera.

DEI has a document about how to solder wires to the circuit board inside the driver's door, but I don't think it's worth the trouble.

I'm pretty sure Trilogix (www.bypasskit.com) should have firmware for their XK01 module for the CTS by now.

the wire should be GREEN Pin # 1

This is the DATA wire, i double checked with bypasskit for their wiring pinout, and also checked with Fortin data wires and they are the same.

Did you order the XK01 directly from Trilogix?

Do you have a way to know what firmware is in your module? (Do you have the XKLoader cable?)

Does the sticker on top indicate which firmware it has?

According to their site, you need..........ah, I was just there and I forgot.....GMDL something........ if you go to www.xpressdownload and type in your kind of car, it'll show you.
