2014 Defender 90 Puma 2.2 SW Santorini Black

PUMA MY2014 junction box battery relay identification

Hello all,

I've probably missed something obvious so far in the various doc that I have (owner's manual, microcat, electric library, wiring diagrams), but I can't find anywhere a map detailing each relays position ! Can somebody help me please? see attached photo. (Fuse position is indicated though but not relays).

Click image to enlarge

What I've read on the forum about stolen parts and motors kind of scared me, and although we don't seem to have that kind of issue in my sector (North France) : better be prepared than sorry as you guys say ! So I'm in the processe of "layering" the security on my def. Ardcase has been ordered, Stoplock already in place, epoxy for bonnet and door screws is alsmost done, as well as bonnet cable lock protection plate. Now is the time to fit an hidden cut off switch (starter relay or fuel pump I have not decided yet), hence the request !
If you consider the answers are too sensitive to display on a public forum, well do not hesitate to PM me. (As well with additional ideas or suggestions I did not get from the various topics on the subject).

Thanks a lot

6 = R134 Front Wipers
7 = R103 Fuel Pump

4 = R123 Headlamp

So the headlamps are relayed now? No need for a swedish cable loom?

There has always been a relay in the circuit for Defender headlights - it is energised by "ignition on" and ensures that the headlights only come on with the ignition. It doesn't alter the fact that the full headlight current passes through both the light switch and the high/low beam (dip) switch.

The high-current contacts of the relay are in series with the two manual switches.

It does, thanks LesDef, really appreciate it.
Did you got the solution by looking at the wires or Have I missed a document somewhere ?
Thanks again

Hi TonoDef,

I have moved the under drivers seat (RHD) electrics to a box inside the cabin under the centre consule.
During the proccess I noted the wire colours to each of the relays and checked them against the wiring diagram.
I have not found any documents to designate these relays.
Simple for an Electrical Draftsman.

Gidday nitram17,
No photos of my work, at the time I was in a hurry preparing to for a trip across the Simpson Desert.
You can check out the Ex-box at http://www.expeditioncentre.com.au/exbox~4516
Don't know if your at Newcastle pommieland or NSW which will effect viability.

Not completely true since 2012 model year. Whilst the dip switch does carry the full lighting current (and is still the weak link), the headlamp switch now operates the relay in the junction box. The relay that enables the headlights with the ignition on is by the main fuse box (bottom row, right hand side)

Fifth Horseman,...does that mean that the headlight switch in post 2012 Defenders is not so "vulnerable"?

Yes, the main switch now only carries the current for the sidelight circuits and activates the additional headlamp relay. There was a tech bulletin to bypass the main switch with a relay on earlier vehicles. https://www.defender2.net/gallery/albums/u...0relay.pdf

Shame L/R didn't use relays to bypass the dip switch, but then that would give us nothing to modify....

Is one of the relays shown the glow plug relay and does anyone have a part number for them?

Interesting thanks. I didn't know about that TSB.

A very complex way to do half a decent job!
