Driving Light Wiring

Confused aint the word. Lost me midway through the 1st sentence. Really ahve no idea what language your speaking there mate, but wouldnt mind learning it thats for sure.

GJC074 seems to think they are negative switched. Any ideas how to be certain. I really dont understand what negative switched is.

How do i check if its negative switched sorry, with a test light what do i have to look for. Than ks for the help. Its just i have Lightforce 240s that were hooked up with an ABR Sidewinder harness by an Auto Sparkie and he has added a 2nd relay and ran extra wires to other relay and to battery and earth and i dont understand why. I now have another Sidewinder harness for my Hella 4000s and i just wanna know if its easier to wire it myself or just use the Sidewinder harness. I really dont know why they added extra wires and relay.

Sorry ,my vehicle just got home and it is positive switching.
To check with a test light, place the alligator clip to earth and using the probe side, with ignition on,check to see if there is power to any of the wires at the plug on the back of the headlight.If no power is there then you have positive switching.To find the high beam wire get somebody to use the flashing mode on the blinker switch and see which wire causes the testlight to light up.I find it better to use the flashing mode as you don't get confused with the lowbeam wire which will light the testlight up if you turn the headlights on whilst checking.As for the wiring harness you are talking about I have not seen one. sorry.Did the auto elec use two relays,one for each spotlight?

My test light is the LED type and shows red or green.
If you put the alligator clip on NEG and the probe on POS it shows red, If you put the alligator clip on the POS and the probe on NEG it shows green.
It comes in real handy if you don't have a multimeter and are searching for faults.

If you've got two live wires you have a negative switched system and the other wire is the low beam wire switched to ground by the dip switch.
Connecting the relay positive to this means you are powering the relay through the low beam light. This reduces the voltage to the relay and wont do anything for its reliability.

OK I know it will work but that doesn't mean its the right way to do it.

If you got 2 live wires on low beam then switch to high beam and find the wire that's not live. connect that to relay ground 85 and connect the relay 86 to the battery (through the a fuse.)

If you only find one live wire then you need to switch to high beam and find the live (other)wire and connect that to relay positive 86 and connect the relay 85 to ground with a switch in whichever line is easiest

This might help (or confuse further).

Hi Lex M, so when I did my lights a few weeks ago I put the aligator clip on the negative of my battery with the ligts on normal beam I stuck the pointy end in one of the wires, nothing, stuck it in another one, nothing, stuck it in the last one left and the light come on the test light, presumed this was the power for the normal low beam, flicked high/low beam switch to high and found one of the other two wires now lit up the test light one of them still nothing so presumed it is the earth??. Turned off the high beam the testlight went out so I used that to activate the relay for the driving lights to come on. So with all this does this mean I have a positive switching not negative ?? Hope all makes sense to you. Im just a bit concerned that with your reply "it will still work" right way/wrong way. Dont want to burn anything out. have been useing them so far no issues YET. LOL. regards Steve M

I see no problem with that. That's a positive switching and should work fine.
Exactly what I said in the last paragraph above.

cheers

WHOOPS CORRECTION.

should have proofread as well as spell check.

If you got 2 live wires on low beam then switch to high beam and find the wire that's not live. connect that to relay ground 85 and connect the relay 86 to THE THIRD WIRE. THE ONE THAT WAS LIVE ON BOTH LOW AND HIGH BEAM.

Thanks Derek. Friday night and within 2 hours i had an answer to the question that had me stumped. Thats what i call customer service and dedication to the job. Thankyou to everyone else who replied too it all helps.

Hi there Derek, Referrg To Lex M's reply above "it will work either way".I 'm pretty sure it was the hilux Im referring to (not 100%) but I remember doing the driving lights on one of my vehiclesand when I turned the lights off the driving lights come on. Turn the headlights on the driving lights went out, would this have been the negative switched situation ?? I ended up getting done by auto sparkie as it had me stumped.I have just done the prado myself (lighforce) and wired up as what you would class the norm (positive switch). So if I have done it the wrong way with what Lex M is saying even though they are working it could be the wrong way ??? Dont want to burn anything out. Regards Steve M

You can get back feed through the globe filaments. If in doubt do the test with both the headlights unplugged.
