I'm intending to instal another reversing light, as well as LH and RH indicator lights into the vacant spots in the upper set of unused rear tail lights in my 2003 Patrol. My problem is that I am having trouble identifying the harness which I need to buy. What I am looking for is a harness (or harnesses) which contains a GU compatible reversing light as well as amber globe sockets for the indicators. I am told that one of the later model GMH vehicles has the correct harness.

I'm hoping that at least one of you out there has already carried out this modification and can steer me in the right direction.

Many thanks,

EeJay

I fitted a second reverse light and a another set of brake and driving light combination to my 2005 GU. I made-up mu own "harness" from automotive wiring I had already and some plugs I got from Autobahn. I found that the GU already had brake and driving (I think indicator cant quite remember)sources behind the left hand side vertical light. There was brake and indicator sources (no reverse or driving) behind the right hand side vertical. I used a multimeter and the wife to find which wire does what.

I got a set of globe holders from the wreckers for about $7 (old pathfinder). I separated out the appropriate wires, fitted the plugs and ran the wires to the globes. I ran a harness from the left to the right hand side for the reverse and driving lights under the carpet. I drilled holes into the back of the reflectors to accommodate the globes.

The whole job took about 4 hours and about $50.

If you have any questions then let me know.

Angus,

I am chasing the same info as Eejay. I have an '05 GU and tried to identify which wire it is that lights up the one pathetic little reversing light.
I installed a second reversing light under the bumper, protected by the towbar and would prefer to run it together with the existing reversing light.
I tried to undo the rear light but cannot make sense of the bolts and clips that hold it in place. I cut my hand and even tried to look into the rear panel with a mirror but still cannot work it out.
The wiring loom on the rear left going into the tail light has a spare sub-loom with a plug, do you mean that for the additional lights?The main loom has all sorts of colours but I did not want to cut into all of the wires to randomly find out which one the reversing one is. Which colour did you use? Also, what wattage light did you install? Can the wiring handle it and did you upgrade the fuse? Help!

I shall have a look today for the colours. I made up my own harness which was not hard. To remove the rear lights there are two bolts behind the access panels either side of the rear compartment. Undo those (just the top and bottom) and then gently pull the light away from the vehicle working on the outside (look in the manual for the diagram). The clips are rather strong. I stole the globes from my wife’s car which were the standard 21w (I replaced them later). I did not upgrade the fuse as I believe that the extra three globes did not add too much more to the circuit and I did not want to risk burning out the wires. The wire I used had the same core diameter as the existing. So far I have had them for two months and plugged a trailer into the circuit with no ill effect.

Which model did you get?

Angus

I would look at upgrading the fuses mate, even a 21w light is just under an additional 2 amps, so it might get close to its theoretical blowing current and would deteriorate over time at that level. When I had my GU fitted with the Arab spec lights the fuses were upgraded after the indicators stopped working after a 30 min drive, don't forget also that the fuse also has to cope with the piddly lights in the bumpers also.

For JOSPOD,try again. Sounds as if you have run an extra, higher wattage reversing light under the bumper? If this is the case, has it been run through a relay or direct to the existing wiring? If direct, you may have problems with the factory wire feeding the light and it may burn out. Better to run the existing feed to the realy to switch the reversing light feed from the battery. If you are having trouble understanding twhat I have said, see an Autolec!! Hope this helps.

i have a 02 patrol and installed the bulb holders on the wend. used gu patrol globes, cost $11 from the wreckers. they are different globes than the existing but who cares. drilled the holes (watch out that you don't drill trough and hit the inside of the lense - did that twice). prob was all the plastic that entered the hole and then worked its way between the lense and frame. taped a bit of hose to the vacuum and got most of it. got one question, the lense heats up a bit and the left light assembly didn't have any holes in it but the right had two small ones i nthe back - one behind the blinker and the other behind the brake. i siliconed the globe holders in (bit rough drilling) but left the holes in the right light. figure if no dust has entered by now that would be ok. they are sweet - just like an xmas tree

John, if you reply to the reply above JOSPOD will get an email telling him you love him, (in an information sharing kind of way) just like David intended.
