I was wondering if the m42 has the same ecu plug as say a m20? I have a broken 87' 325is ecu and I want to wire the MS into the factory harness so a plug would be nice. The 325 ecu is at home in gboro so I can't look at it but maybe one of you guys knows? :rolleyes:

i can send you my cooked m42 ecu for comparison, along with that antenna if you want.

no extra charge.

*edit

lol just read it twice over, you need a plug for comparison or would the actual ecu be good enough to compare?

well I have a broken 325 ecu but I know a m42 one would work

I can compare the 325 one to mine when I get home sat but if you don't want that broken ecu I'll take it. But you may want it if you go MS later I guess.

if nothing else a pic of the plug would be cool

they are not the same,
both a 3 row but the M42 is 88pin while the M20 is 55pin

Just a suggestion, but BMW sells break out boxes for diagnosis. Have male and female plugs on the part. Probably costs about 100 bucks to get one though.
