Anyone got the pin diagram for a standard height exhibit switch?
Also the bulbs are incandescent bulbs are they? So don't need a certain polarity? As I'm switching ground through my switch I'll need to supply power to what's usually a ground.
It should be possible to get the bulbs working yes? Particularly the bulb for when the switch is closed.
Edit: If all else fails I'll pull the switch out and get a volt meter onto it I guess.
Hi Steve
I will go down to Burson today and purchase a four pin diode protected relay. When I have it, I will come back for some further assistance so that we can get out of this forest.

Yes a multimeter and a 12V power supply should sort the mystery out !

Hi Steve & Others
Finally, purchased a Relay with diode protection. Jaycar could not help. Ended up at Repco and have purchased a Narva P/No. 68032 which is 12v, 40amp, 5 pin with diode. Could not find a 4 pin one anywhere. Basically the same but with dual outlet 87 & 87A. Here is the link to the circuit diagram [URL="http://www.onlineautomotive.com.au/Narva-Normal-Open-Contacts-5-Pin3?keyword=68032&description=1&model=1"]
It is not completely correct as it does not show the diode between 85 & 86 but that is where it is and the current runs in that direction from 85>86.
Attached are the wiring diagrams for the fog light switch and the main beam headlights.
My thoughts were to take the power off the high beam wire (blue/purple UP) just behind the right hand main beam 2 and connect to the relay.
If you can assist with what needs to be connected where, I would greatly appreciate your assistance - thanks.

87a Not used ( cover/ protect this terminal as it will become live when lights are off Or use a 4 pin relay )
87 +poss feed out to lights
30 power from fused feed from battery
86 Power from main beam + poss feed
85 Through switch to - ground
Hi Kev
It looks like you are picking up the correct high beam feed.
Connect this feed to terminal 85
86 is the earth which runs back to your interior switch.
Your main power should be connected to 30, via a suitable fuse
Your spots should be connected to 87.
That should have you lighting up your way ;-)

Steve
Correction, Wayne is correct here, 86 is the high beam feed and 85 is the earth feed back to your switch, sorry about that !
Hi Steve & Wayne
Thanks for the replies.
I notice that you have different views on where to the main feed is connected to 85 or 86. 85 appears to makes more sense where the current will flow from 85 through the diode to 86. The diode should stop any spike going back.
On the fog light switch (through the switch to ground) which wire do you connect to? There are four wires and on the wiring diagram and it shows that the black goes to earth, red/white for interior lamp, yellow/red appears to be the feed and red/yellow to the fog light. I have tried trying to make the switch work as a switch to earth but nothing appears to work. What am i doing wrong?
Can you enlighten me.
Regards
Kev
I can't remember exactly, but off memory when looking at the rear of the plug, the top left and middle left pins were switched. I measured it with a volt meter.

I hope you don't mind me interrupting the conversation, but I think your switch might be the problem. The fog light switch is what is referred to as a momentary switch. In basic terms it sends an on signal to the BECM when you push it once then another signal to the BECM to turn off when you push it for a second time. Essentially, using a fog light switch is not possible for the operation you are trying to achieve. The switch type you need is one such as the inhibitor switch (the one immediately to the left of your fog light switches) you switch it on and it stays on.
Whilst I have not done it, you should be able to remove your fog light switch from it's housing and replace it with the inhibitor switch if you want to use a more appropriate looking symbol for the switch.
