So from what I understand you to be saying is: The switch on the PV IS the low fluid level switch. My reason for this question and as it stands: my be confused is because other in this thread state that the 86 doesn't have a low fluid level switch that illuminates on the dash. Perhaps I'm misunderstanding them or maybe we are talking about two different components.
Primarily, I'm interested in sensing when my brake fluid level is low.
I thought the 86 GT had such circuitry that operated off the switch on the Proportioning Valve wiring.
I was hoping to somehow swap those wires over to have them work on the 93 Cobra Master Cylinder. During the 5 Lug Conversion, the stock Proportioning Valve gets gutted. IDK if this will effect the OEM switching process for the "warning Light?" In addition, I am thinking, now that you have enlightened me a bit on the PV circuit, that my idea of using the switching circuitry on the 93 Cobra Brake Reservoir would in the end be redundant, as the OEM PV for the 86 will handle this task....Is this correct? I notice you location is in Canada, I just want to make sure when you say "warning light" you don't mean brake lights.... No offense, sometimes different countries identity car parts differently. ie. bonnet = hood..lol Thanks for your reply for sure!
I found a photo of PV cut-a-way. (THIS IS NOT an 86GT PV) Trying figure out how this would work as a low fluid warning circuit - mechanically....
This is an 1986 Mustang GT Brake Pressure Control Valve:
