Also, the 2 grounds are supposed to go on the same wire, but not joined. They should go 10-15mm apart along the wire.
You had much experience of settings these up on an FRS, had one fitted today and we've been unable to get it set up properly. It suffers from boost surge, ie the boost reaches a certain point ie 19-20 psi and then instantly drops to around 15ish, then surges back up.
