I have the low level bulb (brown & orange wires, Tan wire from the tank and brown & orange wires from the PAC box. I'm guessing the 2 brown & tan get wired together? And the two orange wires together too? I have the underhood green and a green from the PAC box, these together? This leaves only the red wire & black wire form the power inj. bulb. The block has three terminals, one looks to be the ground or bare wire from under the hood. What goes to the other 2 terminals? I have instructions but they're from a newer kit and a little different so thanks in advance for any help. David
