Yesterday I tried to install a DIC in my 03 GP GT but I had a few small issues.

1. HUD-B3 LT BLU Switch I could not find. There are two 18 pin connectors behind the guages but not a 16 pin one that that wire should be on. Do I need this?

2. On the old DIC I have one wire still connected it is OD-F the wire looks Gray but I think GM considers it LT BLU. Is this pin used?

3. When connected the trac light is on (GTP DIC in a GT) but nothing else works. Nothing changes when any buttons are pressed. Any sugestions to check.

I think it could be my DLC connection so I will check that tonight (I used to big of a wire so the vampire tap I think did not connect.

If that is not the problem what wires are nessassary and how would I check if they are working? (I know how to test the power and door wires)


Also to fix the trac light from staying on when it needs to be off can I just reverse pin A3 and B2?
