Hey on the v-afc is says to add the VTM wire if your car is equipped with it. What is it they are talking about and how do you know if your car has it.

 

look in the manual that came w/the vafc. there are diagrams specific to your car/ecu as to where the vtm wire is located on the ecu. if your car doesn't use a vtm signal than you don't use that wire. the manual goes over everything, if it didn't come w/your vafc you can download it from apexi-usa.com
