Re: TU/TD Column Shifter & Wiring
Hey Clint.
There is only 2 wires on the original switch shifter arm as it originally communicated with the BCM. To use tu/td you need a 12+ into the switch and a resisted wire for the up and the down independently. You also need to set TU/TD enabled and set to “wired” in the tune.
Not complicated if you just want a momentary switch on the dash or something. But the shifter will not just work without modify the shifter switch.
