Wiring loom plug

[Pger]

Hi All,

Just a quick question...
Is all C101 plugs on E30's the same apart from pin no.20?
I am doing a m52 conversion into a 318is and have a c101 loom from a 320i e30. Will this plug mate with the 318is if i use it to join onto the m52 loom?

Thanks

Yes, 20 pin C101 plugs are all the same, apart from the pin 20 thing which you already know about, although the 6 pot loom will have a few extra wires fitted for the 'check' system.
