Electric Window and Central locking Harness

Gents

I am intending to fit Electric Windows and Central locking to my vehicle which came in a poverty spec from the
Factory.
I will be using genuine parts most of which I still have to source ( I will be posting a Wanted Ad shortly )

I have discovered the wiring tucked away in the door pillars for both of these mods as well as the wiring in the dash for the
Electric Windows..

I will need the harness to connect all 4 doors for the central locking and the front door Electric Windows portion.

Is it possible to source this harness as a whole or does it have to be bought in pieces from either Landrover or for Instance
Brit Car which look like they can provide most of what’s required.

Any help or advice is greatly appreciated.

You'll need the door harnesses and loom that runs from drivers under seat to rear door and across to other rear door.

If you have the connectors in the harness then you should have all the "body" side wiring.

So you just need to get the door looms, is that correct?

This is what I have so far.

So the first photograph shows at the bottom left the 3 wires going into the connector and a single wire coming from the other side going to the interior light switch.
I can’t find any sign of the 3 wires on the other side, just the single wire for the interior light switch!

Apologies for my poor photographic skills.

Would it be too much to hope for that the alarm module ( 2014 Puma ) actually has the CDL relay fitted.
It is the newer module not the 10as.

I think what Romadog has said is what I need.

You could do a quick test to see if the central locking is enabled.

With a meter or a test bulb, check if you get a 12V pulse across the plain orange and plain pink wires when you press the fob buttons.

You can do this at the black plug at the door or the 3 pin connector for the rear doors in the seat box.

You would be changing the current rear door loom with the single purple/blue wire to the one populated for the motors as well (orange and pink).

The "full" loom for this is YMM000341 or LR016438 or LR030062

Forgive my ignorance Martin but is it to test each wire
when earthed or bridging the pink and orange wire then pressing fob?

If you put the meter/bulb across the pink and the orange, then you'll get a +12V reading one way (say, lock) and -12V the other. Or a flash from the bulb both ways

So for clarity: across the two wires, not from each to ground
