2007 Tahoe, Clifford RSX 3.5, Autostart

2007 Tahoe, Clifford RSX 3.5, Autostart.  Looking for professional pointers from experienced installers:

1.  Do I have to go into each door to mess with the 5 wire actuators?  I have read this somewhere . . .

2.  Does anyone know if there is a harness adapter available to help cut the installation time?3.  I bought a 457GW (GM Remote Start & Door Lock Interface Module) (databus interface) from Directed.  Is this correct for a 2007 Tahoe?  Any tips on making it work with the RSX 3.5?  I'm not even sure if it uses Passlock or is just a plain key.Thanks!

yes 475gw will do all the work for you lock unlock & key bypass all you just follow install book when you buy 457gw

DEI does not list the 457GW as being compatible with the 07 version of the Tahoe, only through 06.

I'll second the 457 not being compatible. The Passkey3+ system needs a 556uw and will require it's own key. As for locks, as twelvoltz shows above you will need 6 relays to do door locks. I've heard of alternate methods, like opening the drivers door control module and soldiering wires directly to the switch circuit board to make a negative pulse owrk, but i've never tried this(not to mention GM warranty issues). No harnesses are available yet for this body.Mike M2

Go to www.bypasskit.com. They have newer programable modules that work on these trucks. They have one for the locks/alarm and another for the hybrid Passlock II/Passkey III immobilizer system.sparky
