Hi to all, I have this problem:

I have connect the first 2 relays (n.1 and 2) to servos for the A/T disconnect for TQ

1 relays (n.3) is connect to solenoid for disengage the Parkbrake when I press the Brake (pedal)

All work ok but when I disengage the park brake the relays 1 and 2 disconnect too, I have try both with and without the external power but is the same.

Anyone can help me?
