Hey everyone.
I'm doing my due diligence on installing this unit and was wondering a couple of things.
A) Has anyone installed the HD Tuner with this unit? (GEX-P20HD) And if so, what do you think of it?
Is there an installation manual online for the GEX-P20HD?
C) Parking Brake lead question. According to the install manual, it says that the parking brake lead needs to be installed on the power side of the parking brake switch. Is this lead actually looking for power? Or for ground?
D) What features are disabled if the parking brake lead is not connected?
Thanks in
