WJ booster/master cylinder users-a question

I'm buttoning up my WJ booster/master cylinder install on my MJ, and I have a question for you guys that have already did this upgrade. Has anyone tried using the sensor in the side of the WJ MC? I thought about using this instead of the sensor in the proportioning valve.

I have no break fluid light... lol

If you really wanted to try it out you should take a multimeter to that and fill/drain it to see what the sensor does. If it's just an on/off switch you can hook it up to whatever you want.

naw it doesnt work one is a switch when low brake pressure is present-the wj is a sensor that changes resistance
