need a tac module # to use a 90mm ls2 throttle body on a 04 chevy truck.got the spear tech harness already.does a tac module even exist to make this tac and throttle work.dont wanna use the dr x box so need help thanks guys

 

This place sells wiring pigtails if that helps any. It is probably just figuring out what the stock wires do and wiring up something to change the pin locations...

12574221 is that it?

Speartech sells a tac module also

Yikes like $150 for a new one. Junkyard time!
There's one on ebay for $75 if that is what you need.

 

you need the older tac module. 02 i think. why not use the torquerush adaptor? it works great on my 04. plus from what i have read the speartech setup wont open 100%.

 

well i know guys but i had used the drx box before and had lot of little issues so decided that tac mod was more straight forward.i was just trying to see if i had the right mod. for thr ls2 throttle body in a 04

 

i had issues trying to use the tbss t-body. once i switched to the car style i had no more problems. its been over a year and it is my daily driver.

 

by any chance do u have the tac part number

 

Part # 12574221, as already posted above.

 

thank u
