    **UPDATE**
    I tested the wiring harness and it checked out pretty good. Tried bleeding with Autel ap200 and the actuator never kicked on. Have decided it’s the actuator itself and will now install a new unit. I’ll update when that happens.

    Pretty sure the relays only insert one way, but are you certain they're good?

    I can hear them clicking off and on sometimes when I press the brakes. I think I mentioned that I put the relays out of my car in it.

    The extra wire has to do with the p-lock mechanism. I think that the wire for that is a little loose so they tried to jump it. I will be able to fix that by tightening that connection.

    UPDATE*** I installed the brand new actuator and got it running. But I’m getting codes about accumulator low pressure, right rear hydraulic and something about the relay. I got part way through the brake bleeding and got to the right rear to bleed it, but it doesn’t gush out like the left rear. It barely comes out at all. I may post a new topic about this.
