well, just to be sure Embarassed
what do i have to connect to 86 if I want to use the swith as a regular on/off switch
(I want to turn on my worklight manually, even when the engine is not running.)


Any power source trigger...mine doesnt switch from the main beam (i didnt want to butcher that wiring or open that side of the dash.

Mine has a trigger direct from the battery (all fused)...that is what you will need to do to the relay. Although i switch to earth not to power (a little easier wire wise) Mike

So trying to avoid the extortionist cost of an aux 2 switch, is the heated seat switch circuit the same? Do I just need to change the front cap to use it as my light bar switch ( it cost 8-9 compared to the aux2 50!! Shocked Shocked )

The Puma heated seat switch YUF500150LNF will work, but it's a live-switching switch (the Defender Aux-2 switch YUG000540LNF is an earth-switching switch)

It just means that you have to wire your lamps to suit the switch -

Pin 1 - Live in from fused supply
Pin 2 - Dash illumination
Pin 3 - Not used (but is internally connected to Pin 5 - Earth)
Pin 4 - Switched live out to accessory
Pin 5 - Earth


e.g. -

You can replace the heated seat switch's front with any other, including a modified blank (modified by drilling a 2.5mm hole in its front, to accomodate the tell-tale LED's lense) -

Hey gang!!!! Proper novice here, my new 110 has the spotlights in the a bar and wired in to the proper button on the top left dashboard. The weird thing is they don't work, the button doesn't light up with the rest of huge dashboard which made me think it is a fuse. I've checked fuses but can't obviously identify which it would be, am I going down the right thread as to why the button wouldn't light up or might there be another reason?

Thanks in advance!

Is your switch actually wired-up Question

If so, has it been done correctly Question

It should be wired as per my diagram, which I posted earlier in this thread, here -

http://www.defender2.net/forum/post6360.html#6360


Pop the switch out of the dash and take a picture of the connector and its wiring.

Post it here, and we'll see how it's been wired.

Hello - I think it has been touched on in this thread but I'm struggling to find the actual answer (I am pretty stupid to be fair) - is it possible to just buy the aux lamp fascias on their own, to clip on to another suitable switch body? If so, does anyone know what to ask for and who to buy from? Cheers.

Hi, I know this is an old thread but hoping someone can help. I followed the wiring above to hook up an LED camping/work light on the back of my 90 van. I've used a Bearmach BA10299S latch switch and connected it as follows:

PIN1 = Power (from the spare purple power cable at the offside rear corner - aux outlet on the tow bar circuit I think)
PIN2 = Dash light feed
PIN3 = unused
PIN4 = power out to LED light (without going through a relay as low amps)
PIN5 = earth

The LED light works fine, with LED earthed locally, as does dash illumination but the on/warning light is not working. Oddly, I get the same results without the earth on PIN5 connected. Any ideas how to resolve? Banging Head

The Bearmach switches are a copy of YUG000540LNF, which is an earth-switching switch, wired differently to my diagram above.

It should be wired, as follows -

Pin 1 - From the earth side of the Relay (Pin 85)

Pin 2 - To Dash Illumination Header (or an adjacent switch)

Pin 3 - Not Used (but connected internally to Pin 4)

Pin 4 - To Dash Earth Header (or an adjacent switch)

Pin 5 - Live from Accessory side of Relay (Pin 87), for 'tell-tale' orange LED

Hi PaulMc, thanks but might have to give up on this - sounds like it's beyond my school boy understanding of powering a light and switching it Embarassed . I've no idea where this relay is* or how to pick up pins 85 or 87 or how that eventually feeds power the the light. I've run 3 wires back from the light and spare power all the way to the switch in the dash. If you or anyone could give an idiots guide on what wires to pick up and run I'd appreciate it. Very Happy Otherwise I'll put it down to experience! Big Cry

*no interest in running from main beam or exterior lights as this is for a work light to be used when ignition off - hence thinking using the spare purple in the rear was the answer.

EDIT. Didn't see page 2 of your link - answer is to keep wired as I have it but use different switch?!

If you're using this switch to switch an LED lamp, then you probably don't have a relay - in which case, this switch isn't really suitable.

If you have the LED lamp permanently connected to the live, and use this switch to switch the lamp's earth - that will work - BUT, the Orange tell-tale on the switch won't work, as it requires a separate input on the switch's Pin 5

If you ran this from the LED lamp, the tell-tale would be on all the time.

There are two ways around this problem -

Option 1. Change the switch body for a live-switching switch, and swap over the bearmach engraved switch front.

Suitable switches, are -

Defender TD5/Discovery-2 heated seat switch

Defender Puma heated seat switch

Defender HRW switch

Discovery-2 cruise control switch


The Defender Puma heated seat switch YUF500150LNF is the cheapest, at around £10

This is a live-switching switch, which uses the Black connector.

Wiring for YUF500150LNF is, as follows -

Pin 1 - Live in from fused supply

Pin 2 - Dash illumination

Pin 3 - Not used (but is internally connected to Pin 5 - Earth)

Pin 4 - Switched live out to accessory (LED lamp) - the switch's Orange tell-tale is powered when this terminal is live

Pin 5 - Earth


Option 2. Modify your exist switch's internal layout, to turn it into a live-switching switch.

This is quite easy, and requires a small cut in the internal circuit layout, and a loop of cable from Pin 4 to Pin 5 in the Black connector.

Genuine YUG000540LNF, as supplied ( switch opened up) -

Modified, with position of cut in circuit shown in Red -

By cutting the track at this point, you separate pins 3 & 4

The revised circuit would be as follows -

Pin 1 - Incoming Live from Main Beam/Dipped Beam/Side Lights/Permanent Live (as applicable)

Pin 2 - Live from Dash Illumination

Pin 3 - Switch Earth (for indicator LEDs)

Pin 4 - Switched Live output to Accessory or Relay

Pin 5 - Live in from Pin 4 (for Orange 'tell-tale' LED)

MUCH APPRECIATED PAULMC Thumbs Up Thanks for taking time to explain that - very thorough. I've ordered the heated seat one. I'll bear in mind my earth and live switching in future!
