Need Help installing Boulder acc. rear vision system

[PHATBOYPIMP]

I am would assume the 2003 is the same as the 2006 and there is a black plug that was in the hole in the firewall that was made for the back up camera option. Looking at the firewall it was located under the small black box (don't know what it is) to the far right (looking at the vehicle) of the firewall, maybe six to eight inches in. It is hard to see but it is there, I actually found it by looking from the inside.

The wires you need for integration with the reverse switch (at least it was on my 2006) are up at the top where the mirror is located. I unplugged my old mirror and plugged in the new mirror and it was that simple, everything worked.

Does that help? PM me with any specific questions.
