OK, the center socket is empty so it is only a four conductor.  The wire colors are brown, brown/green, white/blue and I think all white?

If the round plug is my wipers, I'm more confused.  In the pic below you will see a whitish round connector below the booted empty round I'm asking about.  The whitish one is connected to my wiper motor. 

Yes, the 9-pin is the diagnostics.  That was my first thought but knew there was no computer in the car.

Here is the round 5-pin.  It runs through the firewall on its own pigtail.

I'm just about finished with my engine compartment wiring cleanup and I have another question.  There are two plugs in the corner below the fuse box.  One is a nine-conductor molex w/cover attached to the inner fender, the other is a round five-conductor with a boot that is hanging there.

Can someone ID these for me and, if possible, provide a pin-out?

TIA

Yes, and you can verify this by unplugging it, and making sure that the tach goes dead, but I'm basically 100% sure that's it.

Thanks.  The engine is torn down at the moment so I can't try that, but I can put a meter on it.

As far as the coil goes, I have a performance rebuild in my future so I think I will wait on changing the coil until I've sorted out the specifics on that build.  I'll just use the resistor wire for now.

Thanks.  Two quick follow-ups.

Is the black wire that is bundled with the oil pressure sensor signal wire the tach signal wire?

Do I need to run the wire from the starter solenoid to POS on my black coil?  I live in Florida so starting should be easy, do I need the "12v during cranking" boost to my coil?

Let me start out by saying I have searched and bookmarked multiple posts on this subject.  I'm trying to delete the emissions wiring and generally, make sure everything is wired correctly on the 1976 2002 I recently bought.  My wiring does not match any configuration I have seen in the searched threads.  There are splices and it is difficult to identify wire colors in many cases.

I'm also a bit confused by the blue/black/red coil issue. My coil is black with a red top and has part # 0 221 118 335 but there is no resistor block. 

Here is what I have:

One ganged bundle in a blue sleeve goes to the coil.  It includes: A black w/red wire to coil POS, a wire with clear insulation to coil POS and a black to coil NEG.

A separate wire runs from coil NEG to the distributor and it is spliced to the black wire that runs in a 2-wire bundle with the oil pressure sensor lead (red/black).

My questions:

Do I have the "red" coil?

Is the clear wire to the coil POS a resistor wire and the main power to the coil?

What is the second black w/red wire on coil POS, the wire to the starter solenoid?  If so, do I need that?

Does anyone know where the two non-distributor coil NEG wires go?  I assume one is tach lead, but which one and what is the other?

TIA

As a new member and new 2002 owner, I am often clicking on embedded in posts links to find additional information of to view "how to" threads.  It seems, more often than not, I am redirected to the "dead link" page that shows:

  Sorry, we couldn't find that!

We could not find the page you were looking for.

I get the same result in both Firefox and IE.   Do I need to change some setting on my computer or are there really that many deleted threads?

TIA

Just looked a the picture of your rad again.  I see corrosion/crud around the separator on top of the engine.

 

If I were you, I would open the heater valve, drain the block (plug under #4 exhaust port), clean up the guts of the separator, double-check your thermostat for function and replace the coolant.  That way you know you are starting with a clean system.

Thanks for the tip.  I had planned on doing an inspection and overhaul of the cooling system.  Plus, Side-drafts are in my future so that part is impacted. 

Any idea how the cooling capacity of this radiator compares to the Walloth & Nesch "high cooling rate" one?  The W&N one is on sale now and the dollar is strong.

I will be doing autocross and track days.

Duh...

Just purchased a 1976 2002, I live in Florida and am concerned about overheating.  The radiator in my car appears to have been replaced but I can not find a BMW part number on the unit. 

It is a Behr unit with plastic top tank and seems to be mounted in the OEM location.  The only number I can see is stamped on the right-side aluminum frame - 2106012.  I looked on all the exposed surfaces and can see no other number.  A search of the Behr Hella online catalog (and Google, for that mater) gets no hits with this number.  Maybe this is a date code?

Can someone help me with identification?  Where would a BMW part number be on the part?

TIA
