WTB: 2003-2005 Silverado Dash harness
 

I’m in process of a 6.0l to 8.1 conversion. I currently have a donor 8.1 engine and engine harness. I’m in need of some other components and hopefully someone may be parting out a truck. I'm looking for a 2003 or greater, HD2500-3500, 8.1l L18 Engine, Allison 5peed M74, 4x4 with NP1 263 Transfer Case.

I need the following:

1. Instrument Panel harness: This will be the entire dash harness that includes the pass thru the firewall to the under hood BEC on the left wheel well. I don’t need the outside BEC however If it will simply it, great.

2. Throttle position switch harness from Accelerator Position Sensor Assembly to TAC Module.

3. TAC Module

4. Transmission Control Module

Any of the parts would be greatly appreciated.

Thanks,

Mike
