Adding a power outlet to my R1150GS like the R1150GSA

I'm taking a trip to the Oregon coast in a couple of weeks and decided that I need a more accessible 12v source to keep my phone/GPS charged. Unlike the GSA the GS does not have an outlet up by the dash. the only outlet is down on the engine cover. I didn't want any cables strung up from the engine that might get in the way and cause a hazard.

I went online and ordered an oem outlet from the GSA schematics which places it on the fender close to where it meets the gas tank.

When the oultet came it had a funky plug on the back. I went to the BMW dealer and was told that the plug was part of the wiring harness of the GSA and that the GS probably didn't have it. I ordered a plug that would fit.

When I started digging in to the bike this weekend I noticed that the GS actually had the plug. It just wasn't connected and it was zip tied under the dash.

Nice. did a test fit just to be sure. Snap!

Tested it just to be sure it was live. It is but it isn't switched with the ignition so I'll need to be sure not to leave something on and drain the battery

Next I clipped the tie

And checked to see how much wire I had to work with

Plenty but it was pretty corroded. Needs to be cleaned. I used a dremel bit I had which was a small tapered file that allowed me to get inside the terminals

After realizing I didn't need the plug I had order from the dealer I went back to cancel my order. Since the plug I paid for was about the same price as the aftermarket outlets they were selling I decided to pick one up. Figured if I was in to the bike doing this I might as well add an additional outlet. The plug from the dealer didn't require the oem fitting and just used two spade terminals, positive and negative, to wire it up. So what the hell I'll put two plugs on the bike.

After removing the fender I masked off the mounting areas and marked the holes. I first used a 1/4'' bit to drill the pilot holes then finished it off with a 3/4'' spade bit

Remove the tape, clean up the shavings and fit the outlets. You can see from the picture a difference between the two outlets. OEM on the left and aftermarket on the right. The OEM is better quality for sure but was more expensive.

Next I side chained off the OEM plug on the harness and ran the wires across under the dash.

Put the fender on hooked everything up
