Studying the wiring diagrams so I can adapt JWEST's headlight relay kit (1973 911 and earlier) to my '72 914. I'm down to my last headlight switch, and I want to take the current load off the switch and the latching relay. So far, this looks like a pretty easy do...
But like the sign says, "We don't do this because it's easy, we do it because it looked easy!"
Pictures to follow as I get into it.
OK, I finished the install yesterday.
Bad news: I forgot to take pictures
Good news: It's a very nice kit, and it was pretty easy to adapt it to my '72 914
(NOTE: some 1972 and earlier 914s have a "hot +" screw-type junction block behind the fuse panel--if your car is newer, you'll have to find a different "hot +" source).

Installation details follow, just in case anyone else wants to try this (all the usual warnings and disclaimers apply):
- Always disconnect battery BEFORE starting work.
- Insulate all exposed parts of the terminals with heat-shrink tubing, particularly the female terminals that were pulled from the fuse panel.
- Use 1/4" female push-on terminals on the kit's blue and green wires; they replace the car's white and yellow wires (respectively) at the fuse panel.
(NOTE: On my '1972 car, the white and yellow wires are at fuses #2 and #4 on the "input" side--check the appropriate wiring diagram(s) to make sure what's right for your car).
- Put 1/4" male push-on terminals on the relay kit's white and yellow wires; connect them to the car's white and yellow wires that were pulled from the fuse panel in step 2. (FWIW, on my car these wires come from the "latching relay," listed as #27, "combination relay" in Haynes manual, Figure 9.73).
- Install a ring terminal on the relay kit's red wire, then add it to the "hot" screw-type junction behind the fuse box. (NOTE: I didn't add an in-line fuse between the junction block and the relay because I have the wires between the battery and junction fused at the battery.)

- Put a ring terminal on the kit's brown wire and add to an existing ground.
Hope this helps!
PS. The JWest Engineering 914 foglight-flasher relay works really well too!
PPS. Always disconnect battery BEFORE starting work.
