Part of it is my slipped disc, which means I don’t want to contort myself right now, but a lot of it is understanding how to get from the cowling over to the glovebox. I haven’t taken the time (because small spaces aren’t for me right now) to look for a way to track the wire over. Don’t like starting it if I don’t understand the full job.
Hoping for a back miracle any day....

My car is the N52 version. The main bits of concern are
- where the wires go
- what equipment I need.
- how to remove panel below ac unit
- when to refer to BMW instructions
- assume VI I is violet and BR is brown but what does GE and SW stand for?
It'd be really helpful if you could flesh out the instructions maybe add more steps and remove the abbreviations. Basically more dumbed down for he average Z4 owner.
I'm happy to give stuff a go but feel free to tell me to go to a garage.
To end on a positive it looks like a great product
Thanks,
Chris
OK
Tools will vary, but trim removal, torx bits, screwdriver, length of wire, insulation tape to attache blue cable to wire. Heat of some form to shrink heat shrink tube (cigarette lighter works well)
Panel below AC just pulls off from the front.
Refer to BMW instructions to remove the Light switch and routing the cables and then refer to mine for connecting. It's only pin27 and pin31 to worry about on the light switch and the relevant connector in the ECU housing.
VI/GE = Violet & Yellow (pin 27)
BR/SW = Grown/Black (Pin 31)
Best thing to do is have a go. Just looking at the instructions it could look daunting, but it's not a hard job when you have a go.

Hi,
Almost cracked this! At the stage where the blue wire goes to the box in front of the DME case (N52 engine). Grateful if someone can explain how they routed the blue wire through the rubber hose to Pin 39?
Many Thanks,
Chris

Guys if you can get your head around it this has got to be one of the most worthwhile Mods going, I know Steve’s always available, love mine :driving:

So I finally got around to getting this done this weekend. Started it a couple of weeks ago 120 miles from home as I had a work night in a hotel with an underground car park (good space, good lighting) so I took a whole bunch of tools....obviously it was an error as I came up against something that I didn't have a tool to deal with! :headbang:
But I continued this weekend, and in the end it really is a doddle - it's just a matter of getting your head around the instructions.
The hardest part for me (apart from the self-inflicted problem) was getting the metal plate off the LCM.
Then it all became obvious.
I'd be very happy to help anyone do it if necessary (Cambridge area), with the caveat that I've only done the N52 engine. Would love to see how quickly I could do it now I've got it all understood! 8)
Big shout-out to srhutch who took my texts at almost unreasonable hours!
and for a great loom! Now given me the confidence to do the dash-cam hardwire....
