Brake Resevoir

Wonder if someone could take a look at their Countach and tell me where a wire goes?

 

I was out cleaning the car today and noticed I had a wire that was disconnected and I can't find where it goes!

 

It is the wires on the Brake Master Cylinder reservoir that sends a signal to the "BRAKE" light on the dash should the fluid level drop below minimum.

 

The black wire is still hooked up. It goes to a ground post. However, the Orange w/ Black stripe is the one disconnected.

 

Here it is with its female connector

 

Thanks!

My car does not have that connector. I have one black wire and one orange/black stripe wire leading out of a single black plastic shroud/tube.

 

Those two wires head directly into one reservoir cap, and then another black and orange/black stripe pair head out of the first cap into the second.

 

That's it. Car is an 87 USA/FI/QV

 

Don't you love playing figure out the wiring on an old Countach

 

I think if you follow those wires further done, you will find that they connect to a pressure valve that is just behind e steering rack. Its a big brass valve that should have 4 rigid brake lines coming in and out of it. I believe there is a male spade connector coming off it where the Orange/black wire plugs in. The black ground wire attaches to the stud which holds the valve onto the frame.

 

I believe my valve must have gone bad at some point, and the previous owner replaced it with 2 brass connectors. Here is a photo of what mine looks like.

P.S. My stupid iPad always rotates the photos 90° so that's why it looks funny

Forgot to attach this photo from the parts manual. You can see what there a proportional valve should look like. It is part number 16 in this diagram.

And the brake booster and master cylinder is from what car? Its from something else like all these other parts
