Wiring harness

Glack Attack · Feb 13, 2025

Good Evening everyone.

I need a new wiring harness for the temperature slider controls area of the centre console on my 2013 Defender 90. There are 4 bulbs that currently don’t light up. Three of these lit up previously with a bit fidgeting with the controls. I replaced the bulbs but made no difference and now these don’t light up at all. Does anybody know where I could get a new wiring harness? Might check a scrap yard if all else fails.

Thanks.

Have you checked you have voltage at the plug?
You may be able to rebuild that loom if you can’t buy 1.

Didn’t even occur to me to check voltages, I will try that at some point. How would I go about rebuilding the loom? Just a new plug connector?

Quick search & found the T5 bulb holders
Unsure what type plug you have.

The lighting harness isn't available as a separate part.

Neither are the bulb holders, which are the same (or similar) to those used in some Fiats and Vauxhall Corsas.

The only part of the lighting harness that's available separately, is the White 2-way male plug (as well as the mating female connector on the main harness).

These are TE Multilock 070 series.

In fact, the whole HVAC control panel has been lifted from a Fiat.

I posted some info on this, here -

I've searched for compatible terminals for the bulb holders - without success

I will get round to checking the voltages this weekend hopefully. Might just have to bastardise the loom that I have and see if I can get it working some how.

Checked the voltage at the switch, looks like 0V. Might try and take a supply from somewhere else. Any thoughts?

You did check voltage when you put the headlights on? (Just checking)

Do your dash lights work? Thought they would be on the same power supply.

Yip - headlights on and all other lights. Everything works as it should, also the dash lights. I checked the voltage by using my multimeter and sticking the ends of the terminals of the white connector. Would that be right?

Find the feed for the dash lights and check that voltage to make sure you doing things correctly.
Once you have a live & earth,keep probe on the earth & check the plug outputs for power.

You could also check the removed loom lights with a bit of power off the battery if you have confidence
