Where can I find the vss wire and the reverse signal wire in the dash.

The reverse I can always rub a wire all the way to the back up lights. But I have no clue what to do or look for in the vss

VSS - LT GRN/BLK and PPL/WHT (light green/black, purple/white)
Reverse - DRK GRN (dark green)

I'm sure on the VSS, the Reverse light - use your tester to verify.

Where- the body control module is behind the right kick panel - that's where I'd start (because of of those wires go through this) then trace back to the closest source. VSS should terminate at the dash pod... dunno about the reverse lights

I used a wire harness kit that separated that line out. Unfortunately, it goes into a black box so I don't know if it passes through or if it is interpreted from the serial bus. I used a manual switch to for the reverse signal to allow me to turn on the camera any time.

Yep. I initially used the Metra GMOS-04 but I kept getting alternator whine through the system. I have the Monsoon setup so there is an amplifier already in the system.

The PAC module costs a few bucks, but it was worth it.

Just for S&Gs, I went to PAC's website and looked at the directions. I forgot that the PAC did NOT have the VSS pass-through. I remember disecting an old plug from my Metra interface to add a wire from the stock plug for the VSS signal. I will try to find that wire for you. Probably in my online manual.

thanks. i have the pac installed. installed an avid f90bt. just working out all the kinks

Found it. In the original radio harness, it is dark green with white stripe. Here is a link to the electrical diagram (page 90) :link:

Careful, apparently there are two wires that color. Look for the one on pin "E"

thank youuuuuuuuuu

ok so i went to do this today and my radio harness doesn't have a green wire with white stripe. It has a dark green and a light green in it. but the on star "silver box has a connector on it with a green and white strip. Is that it?

I have been digging and can't the OnStar box in my charts. However, I popped the dash apart on my truck and pulled the radio. The wire in question (dark green w/white stripe) is on the small plug for the radio (there should be two plugs along with the antenna).

yeah mine didn't have any green wires on the smaller plug. ill pull it apart 2m and double check when i install the xm to my avic

What year is your H3? 06 and 07 have a D-GN/WH VSS at the onstar module. Most of the wiring is the same through the years but a few changed with the switch to CAN in 08.

07

Is the vss the green and white stripped wire coming from the left plug on the onstar module

What unit did you go with? Been debating on a single din or double. I mainly only want bluetooth streaming

I got a used avic f90bt. 360 used. Then bought the update and xm module. Looks great and works beautifully. It's a premier unit so it has a back up cam. Bluetooth. Navigation. Msn traffic updates and a bunch of other stuff. Plus they are windows base system so you can hack them and modify the icons and the software
