My problems started when Putting the block back in the car. The wiring to the valves were not marked except the red one, I had a hard time figuring out which wire went to each valve. I'm still not sure I got it correct, although After looking at pictures online and looking at the colors of the actual wires, l think I did.

I got every thing back together cleaned the area with break cleaner to remove all the pentosin that spilled, to make sure there were no leaks. I filled the pentosin and raised and lowered the car many times until I was satisfied that all was well. no leaks

On my maiden voyage, I did not get far, just out of the driveway. It was not leaking before I started the job, as best that I could tell. and it is not leaking in the area of the front block that I worked on. Instead It is leaking from behind the front tire out of some sort of "release valve" and out of the rear block. See pictures

Questions:
1. Is it possible I have the wiring incorrect and this caused the issue?
2. Does anyone have a wire diagram showing which wires go to which ports. I have one of the four marked (the red one)
3. what is the part that is leaking, I have searched the forums and can't find any reference to it.

Any help in figuring this out would be gratefully appreciated
