someone hot wired and cut many wires on this old mack dm dump truck. Because the silanoid that comes on with the key died. I fixed that but still need to find and fix low air light / buzzer and the brake lights when the key is on and brake are on. Don't know where these valves are and how to get them working for the d.o.t. again. I know there is two valves on truck brake valve and two under steering wheel shaft. Three are just plastic, one wire ones and the other is round two wire one. I think thats for brake lights when truck is parked, and key is on. how do i wire it to brake light in dash and to tail lights with mess up the blickers.
