Outer Limits 4x4 Board

I am having dramas working out how to hook my spotties into the high beam.

I have taken the 240's off my Troopy and put them on my Commodore (old VP) for a trip from SA to Qld coming up soon. The wiring was already done in the Troopy when I bought it. Have mounted and wired everything up in the Commodore correctly though a relay and manual on/off switch to the dash and they are working perfectly. Now I need to know how to CORRECTLY hook these into the high beam so that when they are switched on with the manual switch they are turned on and off with the high beam as per the law, can anyone help me with this one? I have searched plenty and what I have tried so far has failed.

The manual switch on dash is just a normal 2 way toggle with power, earth, and acc feed going to the spotlight relay. Pins 87 (2 of) are going to spot lights, pin 30 fused line to battery, pin 86 earthed to body, pin 85 to acc feed on manual switch. Have got wiring diagram for Commodore and the wires that are showing high beam are all there. I need to know which way to hook either the switch or spotlight relay into one of the high beam wires or relay so they come on only when high beam is activated.

TIA, Glenn

Hi Glen, Commodores have positive switched headlights and if you have a 3 position switch ( ON/OFF/ON ) you can run a wire from the high beam wire to one of the outside terminals on the switch and then run a wire from positive to the other terminal on the switch.

Then run a wire from the center switch terminal to pin 85.

If you only have 3 position switches, you will need two of them. One wired up as you have in your post and the other has a wire coming from your high beam wire to one terminal on the second switch and then just loop from the other terminal on the second switch to the terminal on the first switch that goes to the relay.

Feed power to your switch from the highbeam wire at your headlight or in the harness to the headlight. That way they ONLY come on with highbeam AND you can switch them off manually. Everything else you've done is spot on.

Yep, I second that. Its the legal and correct way to do it.

Excellent, thanks so much fellas, much appreciated
