I recently acquired a US-Gear Super Duty E-brake…second hand. This appears to be an earlier model, and has different wiring than what is shown on their website.
We are having our local TDR wrench day this Sunday, and I have received offers to help me get it installed. We can still do the grunt work of getting it in the exhaust system, but the wiring is causing a little brain damage.
Here is what I have as far as wiring
Control Box with switch and three LED’s all wires are at least 18 gauge
Yellow - to a defeat switch on the go pedal
Brown - to a defeat switch on the go pedal
Blue – to the pressure sensor on the waste gate on the brake housing
Orange - to the pressure sensor on the waste gate on the brake housing
Red – has an in-line fuse - ?
Red/Black - ?
Black – ground I presume - ?
White - ?
Green - ?
Remote pushbutton switch
Wires are missing. There appear to be three connections that were cut off on the exposed circuit board, may only be two. I will be contacting US-Gear for a new one.
Brake Housing
Main solenoid – all wires are 10 gauge.
Black – Ground
White – Close butterfly - ?
Gray – Hold butterfly - ?
(white and gray may be reversed, they are labeled on the solenoid, I am just too lazy to get up from the computer to double check
)
Pressure switch (I am presuming, there is a air line running from the turbo side of the butterfly to this switch) all wires are at least 16 gauge
Blue – to the control box
Orange – to the control box
What I need to know is where to all the wires with the “?” get connected. I can figure both reds get power, one direct to battery, the other to a switched 12 volt supply. I am wondering if the 10 gauge wires on the main solenoid are supposed to go to a relay. If so, this will throw my both reds to 12 volt supply out the window.
Please, anyone with a, early model US-Gear SD E-brake, please help. I don’t have enough time during normal business hours to call them and try to figure this one out.
