I have a 1994 318i with m42b18 engine. its a 4 door with manual. I just bought it and it has all the parts here but the electrical is not hooked up for example, knock sensors, cam position sensor, crank position sensor, throttle position sensor... and so on. i have a bently manual for it but i can't find anything that identifies which connector from the wiring harness connects were. there almost all the same exact kind of plug. Can someone please help?? Thank you in advanceNee
