I can make you a wiring adapter if you'd like. To help you research what else you'll need the M50/52 & S50/52 subforum is a great place to start.

Yes. I will develop one. The ECU connector is on backorder from Europe so I can't say for sure when it'll arrive.

Questions about A/C come up pretty often for the E36, and while the CAN controller is a perfect solution for those keeping their stock cluster, the same functionality can be had by installing a Z3 instrument cluster, but without the extra programmable outputs the CAN controller provides of course. For those with an E36 who want the basic functions of A/C, check engine light, and oil level indicator a Z3 cluster makes good sense. The Z3 cluster that provides these functions comes from a car that originally had an M52TU, M54, or S54, so that would be model year 1999 and up for non-M and 2001 and up for M. I'm sharing the wiring information because I'm not going to make a cluster harness as a standalone product. Although I can provide wires with pins on them you can plug in with the purchase of an engine adapter harness.

-Wire pin 4 on the X20 to pin 29 on the X60004 (4th ECU connector). For A/C compressor control.

-Wire pin 5 on the X20 to pin 7 on the X271 cluster connector. For A/C pressure switch.

-Wire pin 6 on the X20 to pin 6 on the X271. For “A/C on” signal.

-Wire pin 36 on the X60004 to pin 6 on the X16 cluster connector, (and also X20 pin 1 on an OBD2 E36). For CAN high.

-Wire pin 37 on the X60004 to pin 7 on the X16, (and also X20 pin 2 on an OBD2 E36). For CAN low.

-Remove pin 5 on X17 - Z3 cluster uses X16 pin 23 for battery charge indicator lamp voltage source

-Move pin 11 on X17 to pin 21 on X17 (remove pin that was in position 21) for ABS warning lamp control (except on OBD2 318i models which already have the pin in that location)

For the oil level indicator light, wire pin 9 on the X271 to X60004 pin 21 on a E46 MSS54 or MS42, or pin 20 on a Z3M MSS54. I'm unsure how this will function with MS43 or a Z3 MS42 because on the E46 the signal comes directly from the oil level sensor via connector X6011 pin 5 and on the Z3 the signal comes from the thermal oil level control module (TOENS) connector X19007 pin 9. I don't know if the control module changes the signal. I would try it without it and then install it if it doesn't work.

Question

hi! would like to know if a engine/DME wiring harness from a LHD 1992-1995 e36 325i M50TU25 (manual transmission) vehicle could fit in a RHD version?

Hey,
Yeah, you should be fine. You may just need to take the wiring out of the cover and flip it around.
