Shifter

This might be a dumb Question to ask,,,, what is the use for those buttons on the shifter???? i think one of them sais over drive or something.... not the button to shift gears lol.. the other lower one

Its the power mode button. It raises the rpms for shifting gears at partial throttle, thats if your wiring isn't broken as many are.

There should have been a stock wiring harness installed, or at least longer wires, mine broke because the length was to short.
