I just completed wiring a manual LED rocker switch addition to the oil cooler fan in my 1987. Much information here on how to wire, but, I could not get my LED to work using the fan relay #85 pin to ground side method (not enough current to light LED). I was able to get everything working on the load side if the circuit so I thought I would post my results.

Used a three pronged Radio Shack LED Lighted Rocker Switch. Prongs for Line, Load and Ground. Wired as follows:

1) Line pin on Switch to Fan Relay Pin #30 (Common)

2) Load pin on Switch to Pos lead on fan using wire splice near the factory connector in trunk near the spare tire (power lead is black/ ground is brown)

3) Ground pin on Switch to ground on chassis.

Mounted switch next to Light switch on dash. Fan will work with ingition off since Pin 30 on the relay is hot not "switched". Pulled fan fuse to make sure the fan is protected and it did not work so all is well.
