Howdy,
I own and automotive detailing and electronics installation business here in Fort Worth.
I recently bought a 2006 H3 Base and wanted to install remote start - most systems take 4 hours with soldering.
However, this took me 8 hours.
I have all of the wiring diagrams but was blown away at how wrong they were so I thought I'd post my how to here to help anyone who may be considering installing this option.
First of all, you do not need an immobilizer bypass module for this vehicle - in fact, I tried 3 different "compatible" bypasses and they all failed to actually BYPASS the system.
Use TechDoc 1603 to bypass the passlock system - amazon has a pack of resistors for all assigned passlock values for around $5 and you can buy two relays and harnesses for around $10. $15 for a failproof bypass is better on the pocketbook anyway.

Now for the wiring - I posted the pic of the wiring diagram but here are a few notes I wanted to make:
Locks - BCM Black Plug:
Power Lock - light blue - pin A11
Power Unlock - White - pin A12
White unlock only unlocks the driver's door unless you connect the two-step unlock wire from the remote start - you hit the button twice and it unlocks all doors.
You can connect to the Dark Blue wire at either lock switch in the door to unlock all doors with a single push of the unlock button - I just didn't want to run a wire into the door or cut into the harnesses to chase the wire down.
Door triggers - located at BCM Black Plug:
Front Driver's door - gray/black - pin A32
Front Passenger's door - light green/black - pin A38
Rear Driver's door - black/white - pin A39
Rear Passenger's door - blue/black - Pin A44
Trunk/hatch - common with Rear Passenger Door
My remote start system only had one wire for a door trigger - most people would just put it on the drivers door and call it good. but I isolated each door trigger wire with diodes and connected them all to the door trigger wire.
Once I got it all in and everything figured out, I know I could do another one in my regular 4 hour time frame.
It's not horribly hard, there just isn't a lot of accurate information on this vehicle available.
