If it is a 1000 psi then it would be the Hydrastar for drum brakes. The newest one is # HBA-10 and it has different wire colors, see picture.
So you know that black is 12 volt power in and white is the ground. Blue/white goes to the break away switch. So that leaves red and green. One of those two has to be input to the Hydrastar from an in-cab brake controller.
The other, I am not sure of the function since the wiring for HBA-10 only shows 4 wire connections.
It might be similar to the Hydrastar XL, # HBAC10-CLR. If it is then it will have extra wires, 6 total, and that is because the trailer lights run through it as well. There is no red wire but a brown one. The functions are brown for trailer tail lights, yellow for left turn/brake lights, green for right turn and brake lights.
White is ground, black is 12 volt power, and blue goes to the break away switch.
It is possible that the trailer is using the adapter # HBA-CAM because the previous owner had a brake controller that wasn't compatible with electric over hydraulic brakes. I have included a second picture to show how that would wire up.
