85 cooling fan relay wiring help
I bought a new fan relay connector for my 85 and i need to know the order the wires connect from left to right looking down at the relay with the wires hanging down.theres 5 wires on it.The previous owner didnt have any of the wires hooked up. The connector i bought all the wires are white on it.I have the service manual diagram and ive found the blue,black,green wires and the red wire junction.

If you have the original relay, it should show the layout on the top of the relay, D F as coil, E as common terminal, A as n/o contact and C as n/c contact..

The old connector has all black wires.The old relay doesnt have any letters on it.I think the one all the way to the left goes to the fan motor and the one all the way to the right goes to the battery junction.the two smaller wires that go to the ecm and fuse block(dark blue,green) i dont know which wire from the connector goes to which.

If you look at the pins of the fan relay, one pin is missing.
The missing pin is pin D which is not used.
Red wire from fusible link hot all the time goes to pin E.of fan relay..
Black/Red wire from fan motor goes to pin A of fan relay.
Dark Green/White wire from ECM goes to pin B of fan relay.
Dark Blue wire comes from fuse panel " C Fuse" hot in run goes to pin C of the fan relay.
Extra wire in the pigtail for pin D is not used.
