HELp,I'm struggling here.... I have one orange wire coming from the reverse lamp and the socket is grounded to the dash. The two wires from the trans switch go to the bulkhead connector and there is one wire with a grey female slip on connector coming from the connector on the engine side. On the other side of the bulkhead conn, all I can see are 2 white wires exiting and one looks like it goes to the brake switch I don't see how this can work electrically. I'm a body man that operates heavy equipment so bear with me guys
