The tcs module is just moved to the other side of the battery box I think ?

ARB CKMA 12 Under bonnet install - Not second battery box

it may offer an alternative

Thanks for all the comments and descriptions of individual installations.

Seems as though there are many variations between vehicle models and build year as to what is contained in the drivers side battery box.

Mine is similar to 100kin4 below but with a ECU black box attached to the engine side of the battery box.

I am able to fit the compressor with out moving anything but will need to make up a base plate to secure the compressor as others have done.

My only concern was that the black box covering the ECU may be affected by heat generated during compressor operation.

I may have to relocate the black ECU as indicated by 100kin4 and his yellow highlight.

Thanks again for all the comments

Hi,

This is what needs to happen for me. I guess there must be a link to the original post detailing this move and install.

Is there enough wiring loom length or is this a difficult process?

I looked at this but there is no room to fit that in that position in mine from what I can determine. There was a horn in there - I think that’s the alarm horn? Seems a pain in the backside.

As most have noted already:
*The TCCM (transfer case control module) has been in 3 different spots between D3 - last D4
*D3 the TCCM is behind the main battery, so the box on the drivers side is basically empty.
*D4 (lets call them early models) the TCCM and the glowplug module is in the drivers side box (just where you would fit a compressor).
*D4 (last models MY15, MY16 ?) the TCCM is hard against the inner guard under the brake lines, the glow plug module is in front of the air box. (so plenty of room to fit a compressor).
*D4 (last models) the horn is still over under the brake lines all of it squished up together.

I dont know that I would be overly keen on moving the TCCM in the drivers side box to under the brake lines as it makes getting to it a complete dog.
I've replaced 2 failed ones.

Arent the newer ARB compressors ok for in car use? as in I remember the old ones used to smell of oil and stink out the car.

That pic is a factory position of the later D4. the horn can been seen, the alloy bracket with the right angle top over the TCCM plastic cover can be seen and the glowplug module is no where to be seen as its in front of the air box

Yes. Mine lives under a false floor where the third row seats used to be. Noisy, but not smelly.
