2003 2500hd remote starter ignition wiring issue...

[chupe442]

I have a 2003 2500hd ex cab 6.0 auto and want to install a remote add-on starter that I picked up. I am having issues with "ignition#2" wire. I have the pink (ig#1), the yellow (starter), orange (acc), and all the other goodies. I can not locate a white wire (or beige, or light grey) in the ignition harness. What am i missing here? I have several smaller guage white wires in the module harness but not the ignition harness. Everything I can find on line states that I need a white wire in the ignition harness. Perhaps I am below where it may have parted away but I cant get up in the dash any farther. Do I need to pull the guage cluster and attack from the top? I did find a sight that showed a 2003 1500C that did not show it had the second Ignition wire but that seems far fetched to me.. ANY HELP??

Thanks

Check out this site. And select GMC, then model and year. It has some pictures that might help.

That is pretty cool! Unfortunetly it doesnt show me what I am looking for. I did find the "missing" wires though. They do split out of the ignition key/tumbler and go up and over the top of the column to the fuse panel. Hopefully now i can move forward with the fun programming and optional wires that I may or may not have to have... Thanks!!
