DRx harness

 

You need TAC module GM#12574221 plug and play. Adapter harness from Speartech. I checked on the GM harness and the price is 3x the Speartech. That harness is plug and play also.

 

I have the Speartech adapter harness and 02 TAC module that worked on my 03. If you are interested. Just doesn't open it 100%. The DrX module is what I recommend.

anyone have a link to the dr x harness? is that the only thing i need is the drx harness?

or do i also need an O2 tac module as well... hell im confused... lol

 

damnit dave.... torquerush dot com

either go with the dr x to get 100% throttle body actuation

or vette tach module with speartech adapter for ~85% throttle body actuation

 

Just the DrX module needed. I'll pm you the link.
