Has anyone had any success interfacing DEI 556l with a 06 Hummer H3 Passlock 2? I installed a Clifford RSX 3.5 into my 06 H3 using the DEI 1603 doc, and everything works. Although, I would like to interface with the factory security, not bypass it. I installed a DEI 556l and obtained the R-code (I thought) but it will not start; starter does not crank, I think BCM kills instantly. I can do the r\s takeover, and key takeover. I double checked connections. I am out of ideas. Any help is appreciated.
Thanks,
Sean

DEI says that the 556l will not work with the 06 H2 and H3. There are other modules such as I Data link modules that will interface with the H2 though.

I did one the other day with 2 relays, and resistors. DEI has the diagram. There wasn't a normal bypass available because of the whole starter, keysense, and 2nd ignition being the same wire.
