Question: Wiring Under Fuel Tank

I have to run a wire under my tank up to my headlight housing for my Garage Door Opener. Does anyone know if this can be done with the tank left "on" the bike. The instructions are saying to remove the tank but there's a full tank of fuel and I was hoping I could maybe remove the back mount mount, loosen the front mounts and just tilt the back of the tank up and fish the wire to the front under the tank with a piece of chicken wire. Will this work or am I going to need to syphon the fuel out and remove the tank? I really want to avoid the possibility of a mess from spilled gasoline.

I think you'll scratch the underside of the tank up and cause more hassle then just removing the tank. Although I can't say Ive ever tried to fish a wire under a mounted tank. Good luck either way.

I have done just what you are asking and at least with my bike it worked out well. There is a cable run on the right side of tank if you take your seat off you should see it. Square tubing runs the length of the frame where the wires run. I fished power wire through there from back of tank to the front. I used electrical tape on end of wire snake to keep from cutting anything along the way just to be safe but there was plenty of room.

Take a look, I would not risk it if it's tight in there but it did work fine for me.

I tried fishing my opener wire without any luck. So I waited until I had more wires to go through 2 harnesses (5 wires for shotgun shock, 1 for the opener sense, 2 for the oil cooler fan, 1 for accessory power, and 2 for extra LED lighting) and still I got gas all over the place taking the tank off. Don't forget to get a replacement hose for the crossover. I'd preordered the HD braided crossover hose.

Also, you are right over the engine, so I switched to Teflon wire for my harnesses, and enclosed them in 600 degrees C webbing. Love the opener!!!!

Ride with the bike and run with very very low fuel to after remove only a low level of fuel.
After cut the crossover fuel line to remove the fuel and put in a bottle.
If you have got the stock fuel line crossover in the tank, I prefer cut, because its fit very hard in the two little tubes of the tank and you can break the tubes where the crossover line fit.

I have to agree, the channel is tight and the tank is snuggly fit over the channels. Also you have a chance of scratching the rocker cover if you pull the tank backward.
I have 2 tube pinchers and 2 adaptors that fit the fuel line. I pinch the line, catch the little bit of gas that spills when I cut the line in the middle, insert the adaptors in each end and let what's left in the tank drain out. I used corbin clamps (spring pressure clamps) to put the new crossover tube on. I also made the tube slightly longer so I could lift the tank a bit more in the front.

Sad thing is, I have to pull it again to route my PV/AT cables and an Aux power lead to the bars, I am hoping I made the cross over long enough to lift the tank high enough. If not, pull the tank again...
