Finally finished the job. The bracket and light combo as originally designed did not allow the lights to point ahead without the backs hitting the lower grill. I put the aluminium spacers shown in previous post between the fog light and the right angle part of bracket. This pushed the light forward about 1/4″ providing enough clearance at the back.
I had planned on using the factory wiring set up (see German wiring diagram below) but have any of the pin type connectors (very much like Molex connectors) needed to plug into positions C22, B16, and B20 (multi prong connectors at back of fuse panel). But the surprising thing (well to me anyway) about the stock set up is that the additional relay added to “relay position 7” serves only to supply power to switch and not to isolate switch from the full light current. Just as it is a good thing to install relays in headlight system to reduce current load on headlight switch, I figure same approach should be taken with the aux. lights.
My version uses spade connectors and goes like this:
(this is for an ’86 syncro passenger van)
-G7 single point connector on back of fuse panel to + connector on switch *EDIT* I changed to use G3, X-relay power
-G9 single point connector on back of fuse panel to “30” on relay. G9 is fused through fuse # S20, license plate lights, I swapped in a 20 A fuse.
-connection from switch to “85” on relay.
-connection from light bulb on switch to ground.
-connection from “86” on relay to ground.
-connection from “87” on relay to fog light positive.
notes: the foglight switch is a 3 position switch and has 2 connectors on it, one for front fog light, one for rear fog light. It also has a light in it that illuminates when switch activated. The relay (40A) is mounted in one of those nifty bases that dovetails onto edge of fuse panel. G7 only has power when headlights are on *EDIT* I used the G3 spade, X-relay powered. so it gets power when ignition on. I grounded the lights via the right hand side lower radiator bracket bolt. The positive wire from lights passes through bumper sub frame via a grommeted hole, then up behind grill alongside the left hand edge of radiator then through body via a factory installed but unused grommet.
*EDIT* here is my circuit diagram as used
And here is the factory wiring.
