Its just a boost solenoid.

Correct me if im wrong, you can connect up what ever solenoid you want and get it to work (ie. mac 3 port, prodive 3 port, ac delco). Which is alot cheaper (mac 3 port = $100 ish, prodrive = $200ish, ac delco = $50ish).

Ive got a pfc. but have decided to use a trust profec spec b.
