Has anyone seen this color pin-out on the DIC before? I was told it was a working unit pulled from a 98 Blazer. I attempted to hook it up per instruction (overhead console from temp/dir. to trip) and it powers on but doesn't communicate with the vehicle. I have since hooked up another one with the standard pinout and it works fine. I would love to know if this unit is defective or just a less common unit with a different pin-out.

 

Colors dont matter, its just which wires go to which pins.. Go with this pin-out diagram: Driver Information Center (DIC) Connector - 2001 Chevy Venture it gives which wires do what.. starting at the far left side (looking at the end of the pins), you'll need power, ground, temp ref from the grill probe, and if it's the Trip Computer version, you'll have to run a wire from the OBDII socket, pin 9 to the very last pin(far right). Run it from the socket, up the front doorpost, across the headliner to the display, leave enough slack to be able to hang the console..

 

Thanks for the reply, I tried the link you suggested plus everything I can think of to get this trip computer to work. I have connected a different trip computer with the more common wire colors and it works fine. I'm starting to wonder if this unit uses a different communication method(UART) but then again the compass and temp even drops out. everything shows for about 10 seconds then the numbers turn to dashes.
