Default Help....LSX Newbie!!!

Since an LSX engine makes more sense than an old school SBC I decided to use one in my next crawler project(still gathering parts so no real pics yet!!).

Heres my questions.

I bought a 2002 LQ9 out of a Escalade but the harness and PCM were missing.
Will a 2004 harness and 12576106 PCM work on this engine?? I am planning to have the PCM flashed to remove all un-needed emission equipment.But I want to go with a cable type throttle body.

Do I need an earlier PCM and harness???


Also what is the best year(s) car/truck cable throttle body to use???(I am keeping the LQ9 intake....)

Believe me I have searched and cant really find the exact answers or maybe Im retarded with the search function......

Any help would be appreciated!!!

easier to stand alone harness with either lq4 or lq9 pcm 00-07', flashed to remove emission as youre planning. truck and fbody use same tb design, but truck has larger throttle arm, both 3 bolt 78mm, easier to use cable driven over dbw.

Thanks for the reply....

Just before I checked this thread I called Jims Performance and talked to him about converting the harness and a performance reflash my pcm and he said its really no problem just send it to him.

Good price and he does alot of these for the crawler crowd.
