I am installing the F900 in a 1967 Mustang. There is no e-Brake switch/light. so, my question is, how do I wire it if I have no e-brake switch?

Is it as easy as just grounding the light green wire that I would normally attach to the brake switch... or perhaps just attach the lt green brake wire to a regular switch which is just grounded so I can open & close the circuit (like an E-Brake switch would normally operate) and just leave the switcg closed to ground the wire? Is there any "logic" in the unit that knows if its attached to a real e-brake switch???

I want to make ssure I have full functionality of everything - all the time

-Thanks, Mike
