D-Jetronic: can you (or anyone else) re-shoot the pic of the 1974 AC wiring diagram you posted recently? Parts of it I really need to see are out of focus. Tried to reach you in "conversation." The '74 diagram seems to be unique (not surprised)--other years' diagrams are completely different. Thanks for any help.
 
Bill,
Alan has a copy of this wiring diagram. Do a search for 'aearch', or for the '74 wiring diagram. He will send you one via e-mail if you can't find it on the site.
 
Thanks Gary...he certainly is a wealth of info, and sent me the diagram he has, but it covers only half of the wiring, unbelievably. I am following up with Alan to see if he has more info.
 
Bill,

Now that I am home, I have a couple of diagrams that are not in the original ones, and if Alan Alan doesn't have them, I can send them to you via e-mail. Start a conversation and give me your direct address IF you want them.
I've never seen anything regarding the radio - except for the 12V+ power connection.
 
HERES FOR THE 30

Thanks everyone who has tried to get me the right diagram. I'm still looking. Duh, I should have posted the pic that D-Jetronic posted that is hard to read, see attached (wire colors, where one of the main relay coil wires comes from/goes to...) This is the diagram I need to be able to read. Thanks.

Are you interested in the 74 unique temp sensor and relay to turn condenser fan on? It can be added to earlier cars without the extra relay and control box by using a diode.
 
HB Chris: BINGO! You get the cigar! Looks like this is the correct diagram for my '74, built Nov. 73. Now if the wire colors match what's in my car, I'll be all set. Thanks again.
 
HB Chris: having trouble downloading. Can you email me the jpeg? I'll start a conversation with my email. Thanks.
 
Hi Bill
sorry for being so long.
Moved recently and cannot find my way in all the BMW stuff.
Try to make out your problem and find the notice tonight or sunday the later.
Sorry again
Marc.
 
Make sure you have the battery disconnected when you wire this up. You are accessing direct current to the battery.
