hey i have a profec b head unit and a profec a solenoid i know they can work together but what i need is a wiring diagram of both profec a and profec b so i can make them work....i need the diagram on the wiring that comes out of the head units ...not the wiring harness or how to connect it to the car

 

yup any help on this would be great

 

None of those were ever available to the public. They did that to prevent tampering. You may be better off experimenting with the solenoid itself, but there is no wiring diagram for the unit itself.
