Early E30 to M30B35 wiring adapter

[Jean]

I made two for my swap and one is up for sale $100 shipped.

This will let you install an M30B35 engine with it's engine harness with a round 20 pin c101 w/o cutting any wires into an EARLY e30 car with a rectungular C101 plug.

Here is a picture of the rectangular connector by the fusebox.



I only have one extra.

Thank you.

Bump. Have been tested, speedo/odo, tach, fuel, temp gauges all work with it :)

You have to run 1 wire for the tach from the adapter to inside your car where it connects to the 3 pin connector above the glove box.

Thanks.

Hmmm.... let me think on this one.

To the top. M30 Power is good for your E30 :)

hmm looks like you got it to work...

Yeah, I ended up using my 2nd harness. The tach and mpg wires don't go through the adapter and have to run on their own. Check out my m30 harness thread, I spent good 4 hours tracing X20 pin outs :)
