I have 2 wires coming off my new Painless Harness for the brake warning light. How do I wire those into the single wire off the switch?

• I'm rebuilding my 1967 Bronco brake set up and have lost my stock distribution block. Will this disk/disk proportioning fitment
• How do you hook up the one wire coming off of the valve to the two wire plug on a Centech wiring harness? install
• Will this work on a 1970 F250 2WD with four wheel drum brakes??<br><br>Thanks, Matt compatibility
