wiring spotties
I want to wire a pair of bosh spotties to a 71 super. I want them to go on when I hit my high beam switch on the indicater stork to work at the same
time as my stock high beam. I will be using a 30amp relay. My question is where do the wires go. I know the 87 terminal goes to the lights .The 30
terminal goes to the switch.I assume the high beam switch on the stork?? Where does the 85 and 86 terminals go ( Power) Also Do I need an inline
fuse
Any alternate ideas/methods??
thanks

I hope this comes out!
You are right re terminal 30 (power) & 87 (the spotlights). You obv have a 4 post relay. The image below is one I copied from an optilux 5 post
relay- it may be hard to read but the numbers accross the bottom are 30 86 85 87 87A.
85 & 86 are the terminals that activate the elecromagnetic switch that sends power to the spots. I would suggest that 85 goes to your high beam
circuit (No. 56A??- not sure- check your car's wiring circuit.) & 86 therfore goes to earth.
Are you going to leave your high beam operational?? If you have the orig genny, there may not be enough watts to drive the high beam & the spots.
You'll know that is the case if the genny warning light starts to glow with the spots & high beam on. On a Ghia I used to own, I disconnected
the high beam at the headlights & relied on the 2 spots as a high beam.
Whoa!
I just noticed you think No 30 goes to the "switch". I hope you don't mean light switch. It actually goes to the direct power source-
perhaps terminal no. 30 on the ign sw or even direct to the battery if you're keen. Either way, you will need an in-line fuse for the spots or a
short will fry the wires.

You can wire the lights so that they have three modes of operation:
1) Off
2) On only when high beams are on
3) On (regardless of headlights)
You can install a three position power switch to select between the three modes.
I have attached a pic, but it needs correction/clarification:
The label 'from high beam supply (before switch!!!' should read 'from ignition'. That way, when switched to that position,
your lights will be on whenever the ignition is on, but will go off when the ignition does. You could just as easily take this wire directly from the
battery, but whichever way you do it, make sure it has a fuse in it (probably only 5A - its only triggering the relay anyway).
The wire labelled 'from high beam supply (after switch) is the wire that comes from the high/low beam switch to the headlights high beam (usually
via the fuse panel). This will activate the relay and turn on the driving lights only when the high beams are on.
The third position on the switch should be left disconnected. (ie. 'OFF' position)
The fourth terminal should of course run to the triggering terminal on the relay. :thumb

Cant have too many diagrams no?
I was under the impression that your lights HAD to work with the high beam switch. I know I wouldnt like to be coming the other way while you fiddle
around looking for a dash switch.
This is how mine are. They work with high beam switch, in conjunction with high beam lights. You can use high beam with or without spots using dash
mounted toggle switch.
From a non technical point of view it wont matter if you reverse 85 with 86. It just needs a current flow. Same goes with 30 and 87 I guess.

Thanks everyone for your input. Excellent idea to isolate them from the high beam itself when not needed , say in city traffic. This I will do.
Thanks for the wiring diagrams.

You must wire your spotties so that they can only be switched on if the highbeam is on. It's the law.

Quite right Purple - in all states of Australia (my bug has been registered in 5 different states an I used to have spots so I've checked), you
must have a switch to turn them on but only when the high beams are on - in other words you can have hi beams and no spots, or high beams and spots,
but can't have any other combination.
So the spot light relay must be linked to the hi beam circuit only.
