Does anyone have a diagram or know where the brake fluid sensor wire is routed on a 04 MCS? It seems to go with other wires into the firewall after about a foot. I was told that my wire is severed and needs to be replaced. I can not see that it is severed but my brake light and the DSC lights are on. The dealer wants $220 to replace it which is what I will need to do if I can not do it myself.
