WTB K1100RS fairing piece

[Lawrence]

I'm searching for the small plastic piece that houses voltmeter or fuel gauge (?) high in the inner fairing.  I believe those are found only on the K1100RS model, but I could be wrong.  Either the right or left side would be very welcome.  TIA

I have them.  Which side?

[Lawrence]

Well, I'm not too sure.  I notice that if my voltmeter were mounted on the right side, it would be partially blocked by the brake reservoir - but just partially.  If I mounted the voltmeter on the left, perhaps it would be a bother because that's the side I must partially dismantle to fiddle with the throttle bodies.  Then again, there is the issue of the wiring.  I need to decide where I'm gonna tap into the wiring harness.  You seem to know these bikes sideways to Sunday.  What do you recommend, Mr. Duck? 
Thank you for your help in so many ways.

I'd put it on the left.

The whole system should be at the same voltage so where you tap it in doesn't really matter as long as it's not a turn signal wire.  If you wanted to be a purist you could run it all the way back to the red wire on the alternator or the positive terminal on the battery. (Good idea to use an in-line fuse near the source if you go that route.) Personally I'd just find a convenient wire under the tank.  Maybe the green/black wire that powers heated grips?  That comes from fuse 1 which has stuff that isn't critical for the bike to run.

Just so that where ever you do tap for power is not a constant hot. You don't really want the meter reading voltage all the time(even with the bike off).
