I Have a 2006 Silverado with a 6.0 . It has a pro charger d1sc with a 3.85 pulley and kooks long tube headers and now I am putting a Holley mid rise efi intake. What I would like to know is if the ls3 throttle body has the same wiring and will plug up to my ls2 throttle body wires. Please help . Thanks so much. 😰

 

you have a LS2 Harness on a Silverado? The ls2 TB and the LS3 operate opposite directions. The plug is the same but the logic is different. What TB do you have now?

 

It has the stock ls2 throttle body on it now . The Holley is a 92mm and I'm trying to get the closest drive by wire to that , that I can find.

 

Does anyone know of a kit to change from drive by wire to drive by cable for a 06 Silverado ?

 

A Silverado never came with a LS2 throttlebody, that's what I am getting at. How are you currently operating the LS2 if that's what you have as it had a different plug then a 2006 Silverado.

 

It's a lsx then sorry.

 

I was trying to do to many things at once and messed up my bad .

 

Ok so you have a stock 78mm truck TB then, and want to run a LS3. Google "torque rush".

 

Thanks so much .
