No, I just thought someone else might need it at some point, it was hard won.
I'm not much of an electronic/computer guy and it took me a couple weeks to track down this info.
I'm trying get coolant temp and oil pressure readings into the cab where I can see them, I could just plumb in water temp and oil pressure sensors but I was hoping I could tap into those wires that feed into the DME.

I think I can use the signal from the existing coolant temp sensor but the oil pressure sensor is just a switch that tells the DME that there is pressure so it is safe to start the engine, don't think it is relaying data on how much pressure.

Thank you - great detail and keep us posted if/when you are able to achieve via OEM wiring.

yup thats correct, no oil px data aside from (there is oil px) on the bus. youll need to add a sensor for that. Exellent info up there though, thanks for that!!!

I wasn't able to use the OEM wiring for any of the gauges but adding the the sensors for water temp and oil pressure wasn't bad at all.
The water temp sensor was installed in the coolant drain plug on the block under the header and the oil pressure sensor was installed on the side of the oil filter housing.
I had to fart around with the fittings to get the right combination but it works well now.
I used the push button gauge from these guys, https://blackstarmanufacture.com/produkt/multigauge/
Now I can see what the fluids are doing before the TOO LATE warning light flashes.

Well done!!
Your engineuity should have been on the front end of BMW's Z4M design/construction.

On a much more mundane point, love your CoCo flor mats; their fit and finish and style are at the top of the floor mat market; just ordered a set for my 335is E93 and had them in my Z4MR.

Just wanted to add my thanks, better late than never LOL. I used this when troubleshooting a couple idiot lights on the dash after the automatic to manual swap in my 2007 3.0si coupe.
Which by the way was easier than anticipated aside from a couple self induced wiring/coding issues that I eventually straightened out.
