Re: Tow Haul Mode
For the 03-07 green/blue pcm you hook a momentary switch between J1-pin 71 and ground. Probably the same with the 99-02 pcm, no idea for the other pcm's.

Re: Tow Haul Mode
What we need to figure out is how to make a indicater lightly come on when the tow haul is on without a second switch.
