I have the 4 pin brake switch, yellow brake wire, and purple tcc wire from ECM, only 1 brake switch wire. Yellow wire is on the 12volt when brakes applied, green power wire is connect to fuse box, power when key on. Checked those with a test light, they have power at the right time...tcc wire is on the 2nd set of wires on the brake switch, does wire placement matter?...Also tried red cruise switch wire as the 12v...Nothing. Thanks
