Yes you can use an auto harness on a manual car. It has been done quite a few times.

Or do you plan on using the Auto transmission as well?

no ive just found some auto harnesses but don't want to have to modify the harness for the check I'm doing

and will an auto harness work?

and if for whatever reason i change it to obd2 i just cover shipping both ways? would obd2 include a diagnostic port or would that be on the engine side?

Correct. And yes, only if you request the OBD2 port, then it will be included at no extra cost. You do have the option to use the round diagnostic port (which is on the engine side). But if you use the round port, places such as Advance won't have the diagnostic tool that is needed.

What about for s52?

Sorry, we are still working on figuring the s52 ms41 EWS deletes out. Not sure when these will be available yet though.

I'm on the process of collecting parts for a S52 swap on my M10 E30. IS there a specific harness for the M10 motor? M10 dont have CEL but i want to put one for BAR inspection. Also going OBD1.

Just FYI it's illegal in CA to convert an obd2 engine back to obd1 so you will either have to be really clever about it and pray no one notices or just go obd2

Excellent, I can get one made for you with the CEL wiring. You can use any S50 harness. Or you can use an m50 harness from a 93-95 e36.

Our M54 EWS deletes are now included with our adapters at no extra cost.
Others will be out soon!

ive got an s52 thats converted to OBD1 in an 89 M3, looking for an adapter to go with that and would include wiring for a CEL (since the M3s didnt come with one). i assume it would be PNP if i found an S50 harness?
