if you could create a PIC controller that had 4 programs that could be moved between sequentially then thats all thats needed.
ie. program one would be 12v to S1 and S2, program 2 would be 12v to S2, program 3 would be no power sent to either solenoid, and program 4 is 12v sent to S1.
if you could make the trigger to go between programs in either direction a 12v signal, then we could use any momentary style button, ie. the outer most buttons of the cruise control on a EB fairmont steering wheel, or anything really, could be alot of choices.
if i had the money to buy the hardware and PIC controller id look into the code and do it myself, but i just dont have the time or money atm
