Engine wiring harness question...

[bwh13]

I have an S52 doing the OBD1 conversion using the engine harness from a 95 525i, this is going into my E30.

I am putting on the harness and can't figure out which connectors go to which sensors. Is there a chart giving that info somewhere? There must be 4 or 5 two pin connectors on this harness as well as a couple of 3 pin connectors that I can't figure out what they are sipposed to connect to...none of the connectors have any identifying marks as to which sensor to connect to.

Pull back the covers to determine the wire colors, then go to the back of the Bentley and start matching.

OK I ran into a snag...the crank sensor has a 3 wire plug, but the list of harness wires and their colors says it has 1 yellow wire, but it has 3 wires; yellow, clear and another color which I can't remember right now...do I still hook it up, even though it has 3 wires not just 1? Sounds kind of silly but I want to make sure it's OK.
