Thread: Air conditioning compressor wiring and compatible units

This is a bit of a follow up thread from http://www.aulro.com/afvb/discovery-...te-pulley.html

Basically, I'm now looking at replacing the entire compressor.

There is a seller on eBay selling a unit < Landrover Discovery II TD5 99 04 Diesel NEW AIR Conditioning Compressor CON A C | eBay > at $346.95 with free postage! However:

**PLEASE NOTE COMPRESSOR IS SUPPLIED AS PICTURED AND DOES HAVE A DIFFERENT PLUG TO AUSSIE MODELS. THE INSTALLER WILL NEED TO FIT THE WIRING CONNECTOR FROM THE OLD COMPRESSOR, WHICH WILL INVOLVE IDENDIFYING THE POSITVE AND EARTH WIRES FROM THE OLD SYSTEM. IF ANY ASSISTANCE IS REQUIERED TO DO THIS PLEASE FEEL FREE TO CONTACT US.
1999 Land Rover All Models|2000 Land Rover All Models|2001 Land Rover All Models|2002 Land Rover All Models|99 00 01 02
Fitment Notes:

Supplied As Pictured.
NOT A DIRECT FITMENT

I spoke to the seller further via e-mail who has advised:

when I referred to your vehicle not being a normal vehicle - I mean in comparison to the generic Holden Commodores and Ford Falcons where information on their a/c units
was quite common knowledge and easy to locate etc. I have attached a few pics of the system in question but after contacting that supplier they did mention that this compressor does
have a different plug to the Australian models. With that said it can still be used but the installer will need to fit the wiring harness from the old compressor which basically involves
identifying the positive and earth wires from the old system. After all that I also pushed to see if a direct replacement is available but was unsuccessful.

Apologies we cannot source a direct replacement and apologies I cant provide anymore detailed info.

and provided the following pictures of the unit:








Aside from the different plug connector style on this replacement unit to that of the unit currently fitted in my vehicle, the other issue I note is that it only has a single wire to the connector, when my current unit has two wires.
I note that the replacement unit has a wire earthed onto the body. I assume this is perhaps therefore the second wire.

Current unit wiring for comparison purposes:




Anyone used one of these replacement units previously?

Any comments on the wiring differences?

Anyone able to confirm that the rest of the unit (clutch, pulley, body, etc.) is correct? It looks it to me.

From the us but might be worth considering if your compressor is ok apart from the clutch.

That's a great link. Also available on eBay - http://www.ebay.com/itm/Land-Rover-D...item4abbd0a121

Not sure how to tell if the compressor is ok, hence why I thought to replace the whole lot.

I'm also missing the bolt that holds it all together, although I'm sure I could find out what type and size that is.
