I am installing a Z1 in a 2007 Pontiac Grand Prix 3800 Supercharged.

Ive researched the post here and came up with one close match.

Can any one tell me if the Throttle Actuator Control is the same as the VSS for my car? And, could I get a specific location/picture where to find it..thanks

 

ps. Bestbuy informed me not to worry about hooking it up, the installer stated they dont on their installs. They said the unit will be accurate with in 2 feet with out it. Opinions wanted

 

also I am installing this with a Gmos 04 module.. I am assuming I connect the RCA connector1 to this RCA on the module for sound.

 

Any help in this install would be great. [email protected]
