Gauge sender wiring Z4 M Coupe

I wired my Coupe for four gauges.
Oil pressure, water temperature, oil temperature and voltmeter.
If the oil temperature gauge follows the stock instrument cluster gauge, I will replace it with the voltmeter.

I use black wiring so that it doesn't stick out.
I used #12 THNN wiring. THNN is a smaller diameter.
Fourth wire is for the ooga horn.
Initially tried going from the engine compartment on the drivers side. Not easy to do so decided to go in on the passenger side.
Basically headed towards the front, across under the front cover to the passenger side and back towards the firewall.
Many, many hours to make it look right.
Will add the water and oil temp sender wiring info soon.

Great pics Ron! Does the glovebox need to be removed to access the 'plug' from the cabin side?

No. It's right above the carpet line. Will post a pic after breakfast.

I don't know if it's relevant to you Ron, but BMS has a new billet aluminum oil filter cap that has bosses tapped for oil temp and/or pressure senders. I don't have one yet since I feel like I need one yet, but it's rather beautiful. I might get one just for dress-up and future use. Wish I had a pick

Billet oil filter caps look great (I have one of Ron's chrome oil filter caps) -- until you hang senders off of them. Then they look sort of robocop/hacked in. Plus is makes oil changes messier.

LZ Block clearance with air collector

It is tight with our block also. I am advising customers to install the block temporarily so it is snug, then re-install the air collector to check clearance, then apply final torque.

On mine I just go straight out with an adaptor from Earl's since my temperature sender is in the sump cover of the oil pan (no need for a distribution block). My kevlar hose is longer, but I think AutoMeter sells a shorter one.





Ron's setup looks fine. If it doesn't leak and doesn't make oil changes more work/messy, it gets my stamp of approval.

Ron, do you recall the size of the port where you added the VDO block?

I'm looking to add an oil pressure sender similar to the way you did this.
I'm really not a fan of those filter cover adapters.

Thanks...

Andy uses Loctite 565 thread sealant (Net 1.69 FL.OZ.(50ml). My sealant leaks.

M10 x 1 taper on hose. I think it's into the M10 x 1 straight on the block.
