1983 BMW R100RS Adding Electric Accessories and Farkles

The word “farkles” refers to add-ons and upgrades. I’m adding the following to the electrical system.

  • Eastern Beaver PC-8 Auxiliary Fuse Box And Circuits. I installed the Eastern Beaver PC-8 Auxiliary Fuse Box. This provides eight independent circuits, six fused and two non-fused direct to the battery. This eliminates a nest of wires, fuses and relays when I add the various electrical accessories. All the fuses are in one box and one relay switches power on to the six fused circuits.

  • Heated Grips With 1988+ Wiring. I have the pre-1988 heated grips. The switch for them is no longer available so I will install the later (1988+) two position switch and new wiring between the switch and the heated grip pigtails. The wiring sub-harness contains a resistor inside that provides LOW/HIGH heating in the grips.

    The switch is smaller than the rectangular holes in the dashboard so I fabricated an adapter to hold the switch out of the plug used to fill the empty hole (part# 32 71 1 236 886).

  • Auxiliary LED Lights. To increase my visibility I add two spot bean 900 lumen LED auxiliary lights from Super Bright LEDs. I got the 10 degree beam for the left and the 30 degree beam for the right so at night it will help illuminate the side of the road. I mount them to the rear view mirror brackets and wire them into the headlight power so they are on with the low and high beam.

  • Garmin GPS Handlebar Mount With Power. I have a Garmin zūmo® 396 LMT-S GPS. I ordered a cradle, handlebar mount and electrical harness to power it from Garmin. I will use one of the two non-switch circuits to power the GPS so the it stays on when the engine is off. I like that option so I can select and change routes with the engine off.

  • SAE & USB Power Sockets. I add an SAE plug and a dual USB port so I can charge my cell phone, or power any other accessory. I put the SAE on the other non-switched, direct to battery circuit and the USB on a switched circuit of the Eastern Beaver PC-8 auxiliary fuse box.

  1. Brooks, this has been a fine restoration but why didn’t you extend it to putting a bit of black paint on the rims of the clock and the voltmeter!
    best regards, Martin King.

    • Hi Martin,

      Well, I did do that, but my touch up paint didn’t stick and came off. I plan to pull the instruments when I install the new ClearView Shield taller windscreen and will do a proper job of restoring the black paint on them.

      Best.
      Brook.
