OK, so to make this thread useful to more than just myself, here's your easy 4-pin to 5-pin headlight relay guide:


5-pin Relay_______4-pin Relay___________Wire Colors

56b <------------------ F <-------------------- White

S <--------------------- S <------------------- Yellow/Red

56a <------------------ 56a <----------------- Yellow

56 <------------------- 56 <------------------ Red/White
| (jumper wire)
30

And to avoid having to do any soldering or stuff, Radio Shack has piggyback connectors that convert terminals from 1 prong to 2 prong, you can stick one of those on pin 56 to connect your jumper from pin 30, and still have a prong free for the wire from the harness.

Personally, I found the 5-pin relay pin positions and spacing to be very tight. There are three kinds of piggyback connectors - one that looks like a "Y", another that looks like a "T" with the top two prongs folded parallel, and a third that has one "high/low" prongs. I took two of the "high/low" connectors, broke off the low prongs, and used them to extend the height of two of the tightly spaced pins on the relay to make connections easier.

Yellow/Red -> "S"
Red/White -> "56"
White -> "F"
Yellow -> "56a"

Those are from this diagram here:

Look for the headlight dimmer relay (component "J" in the diagram) and look at the little numbers next to where the wires connect to "J". Those are the terminal numbers that Brad refers to.

Good post Jason.

Much better than the advice I got on the first try, way back in '84, from on of the parts guys at the (now gone) Porsche dealer in Nashville; "Just snap off that extra tab".

Good thing I didn't listen!

Cool!
I'm pretty sure this is on my To Do List.
I had to replace my headlight/square relay and now the high beams don't work. Just need to get in there and make that little jumper connection.
Cheers with beers (I miss the little icon)
