I have searched the boards and tried calling gbodyparts but had no answer, I need a little help. My 86 gn's fuel pump wiring has a black, red, and gray wires with a brown plug. I am trying to order the racetronix setup, but which one do I need? My brother's 86 t has black,pink, and tan wires with a brown plug so we ordered the racetronix part for his. The other racetronix ad says it has black, purple, and gray wires with a black plug, do I get this one? Thanks for the help, ready to order now.
