Re: Spot/Driving light wiring diagram

I posted a similar reply yesterday and read it afterwards to make sure it was accepted, but for some reason it has disappeared from the thread, so I am posting it again today.

Sorry to add more confusion to this thread, but you can NOT necessarily pick the high beam wire by using a multimeter/test light on some modern cars.

I tried that and found that on both my 2001/95 series and my son-in-laws 2009/120 series you will find power on more than one of the three sockets if you leave the other headlight socket attached and if you disconnect the second headlight it will change again and you will only get power from the right hand socket.

I have no explanation for this so I rang RACQ and they were not able to explain the detail of the situation, but said electronics is no longer simple like it used to be and made comment about the need to buy a separate wiring harness for a trailer socket for modern vehicles, because you just can't find the relevant live wire and attach the trailer plug to it like we used to do.

The only analogy I can come up with is broadband computer wiring, where you can use your phone and the computer over the same wire because the messages come at different frequencies. I am not saying this is the same, but it might help to answer the question.

Sadly DIYers are becoming redundant for some tasks on modern vehicles.

Re: Spot/Driving light wiring diagram

Just a little more information about how I chose the correct high beam wire.

I have a workshop manual and researched the wireing diagram and chose the colour coded wire that has the dash, high beam, warning light attached to it, which in both our cases was the top connection of the socket.

Re: Spot/Driving light wiring diagram

So I installed my spotlights over the weekend. I went to repco to buy the Narva switch and while there, I thought I'd better buy a pack of Scotchlocks as well just in case I needed them.

I pulled the socket out and looked at the end of it and it matched MickL's drawing in the 1st post. So looking from the socket end (not from where the wires enter the socket), I chose the right wire which turned out to be incorrect and the spotlights came on on low beam and high beam.

Then I chose the middle wire thinking that the high and low beam wires were switched around but it was the wrong wire. The spotlights came on at low beam and turned off on high beam.

Well, there's only 1 wire left and lucky last, it was the correct one. It had to be the correct wire or I was going to pull my hair out. So in my case, looking at the socket end of the plug, where the terminals would engage, it was the left wire. Good thing I had that pack of Scotchlocks.

Re: Spot/Driving light wiring diagram

Whilst looking for something else i noticed that the wiring diagram from the first post is now missing! i am sure it has helped many people in the past and would continue to do so if it was still there. Having it reinstated in the original post would be best, otherwise if anyone has a diagram and the know how to post it i think it would be useful.

BTW i am trying to work out where the fuse for the fog lights is, i plan to rewire the spotties using the foglight switch as per the last page in this thread. I think ARB must have blown the fuse when they fitted the bullbar :x They stuffed up most everything else, so i now have no power at the plugs that i assume were for the foglights and no indicator light coming on in the dash. already rewired their ruff as guts job on the indicators.

Edit: Sorted my fuse problem now.

Cheers Andrew

Looks like Mick has put a password on his account so it's not visible. I thought you could still posted imnages direct though.

Re: Spot/Driving light wiring diagram

I've quoted Mick's original post - but updated the link to a copy i've uploaded to my photobucket...

This diagram is correct for H4 Globes :!:
Mick

And a copy of the wiring diagram for the Carling style rocker switches (if anyone chooses to use one)....


And my drawing of the NewPro-Tech style switch, with modification drawing for connecting to the IPF loom...


Hope that helps anyone looking for some information...

Re: Spot/Driving light wiring diagram

It appears I have a fault with my spotlights now after not having a problem since installation. Both spotties don't light up and the relay isn't clicking over. I need some fault finding tips.

As it is now, headlights and highbeams are all working. The wire to the highbeam was tapped using scotchlocks, so that will be suspect no. 1. Suspect no. 2 is the relay. I used the wiring loom that came with the RooLite spotlights. Anyone know if this relay is available off the shelf? It is not one of the relays as in the diagram above. It has a white squarish plug which plugs into the relay.

Edit: Looks like a knackerd relay. The position where I had the relay forced me to have it orientated upwards, resulting in water ingress and corrosion. Now getting a new relay and proper flat blade crimps done.

Edit 2: All fixed now. Thanks to all the diagrams from this thread. Bought Narva #68000 as Repco did not have the Bosch relay.

The recommended orientation for installation is to always have the relay mounted connection down and away from areas suseptable to getting wet/muddy. I have mine on a custom backet at the rear passenger side of the engine bay if you want to checkout my buildup page, i think its Chippy (could be wrong), but he has installed a PVC enclosure on the rear drivers side. Just as a few options.

Glad you got it sorted fairly quickly though mate!

I didn't have much of a choice with the supplied loom from RooLite. The loom ends in a plug that plugs into the relay. The closest bolt I could reuse was a bit low and due to the plug, I couldn't orientate the relay downwards.

Glad you got it sorted fairly quickly though mate!

The wiring diagram on here helped sort out what was what and made it easy for an electrical noob like me. Also had help from work colleague with crimper and lugs which made my work easy and looks like it was done properly. Just need to tidy up the loom and try to get the relay more protected. It is mounted behind the passengers headlight, on the sidewall near the battery.

Re: Spot/Driving light wiring diagram

Can anyone help with wiring up 3 spotties. Currently have 2 on the bar want to add a 3rd. The two current ones i have converted to HID and will also do the same with the 3rd.
Is it just a relay upgrade or two relays? Got no Idea

The answer will depend upon the size realy you have. The switched size of the relay will be rated to cuarry a particular current. If the addition of the third driving light exceeds that current then a second relay will be required OR upgrade the original. If you are using two relays then make sure the switching circuit will carry the current the switch both relays.

Re: Spot/Driving light wiring diagram

Also check if its legal. There was a topic not that long ago about Odd number of lights being illegal. Had to be multiples of 2

HID Hi / Lo beam upsetting spotties

G’Day everyone.
Got a bit of a brain teaser, we have a 2004 120 Prado, I installed 2 Rallye 4000 lights as per diagram in this thread, all works well.
Now for the problem, I fitted some HID inserts into the Hi & Lo beam some time later, great lights work very well. Problem is now with the HIDs drawing so little power there seems like not enough demand to pull in relay for spotties. Have disconnected HIDs & put standard bulbs in, all good on spottie front. The HIDs only use one bulb connector as a supply, so with the other side one I put in an old globe, now enough current draw to pull in relay for spotties.
Must be another way to get around this problem that is better then having a spare bulb hanging under the bonnet
Any ideas would be great.

Hey Spike 1,

Did you find a solution to your problem. I am having exactly the same issue now. Just spent 3 hours following the existing IPF wiring loom from the switch to the lights and all ok. Should have checked the posts first. Didn't think the installation of my HID Hi/Low would effect the spotties. Anyone got a fix? The missus now wont speak to me cause I've buggered up the car (again!!). Please help save my marriage!!!!!!

Problem Sorted. Needed a HID Load Module.
