I cant find the FUSE BOX on your download. I still need to find witch wires are the OEM temp gauge wire going into the fuse box and the AUX FAN.I have some thing wired wrong , the fan allways runs and the blower aways runs, and My temp gauge is not working . This is all new since I converted over to the 1.3 motronic.

I can't even remember where I found this PDF. If you notice, it says "Chassis Electrical". I guess this doesn't mean gauges, they must be on another diagram?

They don't have all of the fuses in one place, but spread them through out the diagram. The fuses for the Aux fan and the heater - A/C blowers are shown and the systems are shown complete from the battery through the components to ground.

There is no wire from the temp gauge sender to the fuse box. The cluster is powered, the power goes through the temp gauge out to the gauge sender and grounds through the block. If there are two terminals on the sender one is for the gauge (BN/WH) and the other is for the idiot light.

I believe the cluster is powered with a GRN/WHT wire from fuse #6

I’m looking for wiring diagrams for my euro 635 CSi of 1980. Ideal are drawings containing terminal's designation, types of plugs, relay inner diagrams etc. – like attached example diagram for air condition.

Do You know DVD issued by BMW as prod.no. 01 56 0 035 852? Looks very promissy but I'd rather like to know it's contents before I spend $150.

Anyone ever get the diagram for the 1980 Fuse box? I'm looking for this information for my 1980 BMW 633CSI with an 87' 535is M30B34, figuring out what gets plugged where.

check out the attached PDF, while it doesn't show the fusebox itself, it does indicate what fuses are in line with each device =D>

This is for '80 US spec 633 CSi :-"

Awesome! Thank you. After looking through this I've learned a bit but I'm still missing a few wires. I've got a 12 pin connector with the flat pins:
1: Brown/Green - coolant temp switch, AC/Heater Relay 1, AC Blower Motor
2: Brown/White: Unknown
3: Not in Use
4: Not in Use
5: Blue/Violet: Unknown
6: dual Black/Yellow: To starter (and to test connector?)
7: Green: to ignition switch, hot in Start, Test and Run (Power Window Relay, etc.)
8: Green/Yellow: (18A) Fuse 1, Hot in Start, Test and Run
9: Green/Violet: Fuel Pump/Aux Fuel Pump (Fuse 14, 25A)
10: Black: Unknown
11: Brown/Violet: Unknown
12: Blue: Unknown

Overall I'm trying to figure out how to connect this harness with the engine wiring harness of a 1987 BMW 535is M30b34 that has a 19-pin engine to fuse box harness. I realize it shouldn't be as bad because its putting a newer engine into a car/chassis that needs less information to properly function. On top of this, I am also running an electric fan.
