I installed a Z2 in my 2004 Pontiac Grand Prix. How necessary is the VSS wire? The unit is working fine without it. I tried to find it but it is not listed on the Directechs sheet. Any ideas? Thanks!

VSS Necessary?

It's not necessary, but on a side note, i have a 05 impala, and I have a vss wire, so I'm SURE there is one in the grand prix, check out naioa.com or clubgp.com and ask them in the forums, they could help you on where it is.

Connecting it will greatly improve the response times and accuracy...

right from the directech's websight
Speed Sense dk. green TAC module, pin 4
The TAC (Throttle Actuator Control) module is on top of the engine on the throttle assembly.
