This mod pretty much hides all the wires you could possibly have under your seat. It also replaces the stock plastic piece with a nicer metal tray. Overall it is simple to make with very very basic skills needed. In the end your wires will be protected and there will be a lot of space under there. I had installed a TPO crankcase breather before this so the oil catcher thing was gone and I had made a bracket for the rectifier which is used to secure the tray. If you don’t have the same set up I am sure you can use this as a rough and come up with another solution. Sorry for the lack of pictures I didn't really take any in progress.
MATERIALS
-1 piece of thin sheet metal (or anything you can find at home depot or your local -hardware store)
-2 half inch nylon spacers
-2 Bolts/Nuts
-Can of spray-paint
TOOLS
-Tin snips
-Ruler
-Marker
-Vice
-Rubber Mallet
STEP ONE:
Start by sorting out the wires that are already there. I cut off the stock tubing that surrounds them so I could see each wire. I cut out the license plate light because the tail light unit I have has one. I made sure I taped up any connections so they did not touch. To get the thinnest line possible I twisted the wires somewhat like a rope while taping them around with electrical tape.
STEP TWO:
Take off the stock plastic piece make sure to keep the two bolts and washers for the tail end handy because they will be used later. If you have the stock black plastic tank there and the rectifier in a different location take a look at possible ways to alter this design to work for you.
STEP THREE:
Here is where the actual tray comes in. Take the metal and mark out the lines then carefully cut out with tin snips or any other metal chopping device. The metal I used was thin enough that it could be cut with household scissors. After your tray is cut you will need to find a vice to bend up the sides. This is the most difficult part out of the whole process. I assure you do not need a whole workshop for this. I used primitive ways to get it to how I wanted. Here is roughly the tactic I found that worked for me. I line up the edge I am folding in the vice. For longer edges and smaller vices you will need something that has a straight edge that goes the length of the piece. This helps support the piece as you begin by pushing the edge down with your hand uniformly. Slowly work it until you feel it is ready to be hit with the rubber mallet or whatever you want to hit it with. I used a scrap piece of wood between the metal and hammer as to protect it a bit. Work the folds until they are close to a 90 degree angle. The tunnel where the wires slide under is some what time consuming because the way it has to be folded. Just take your time and you will end up with a perfectly fine tray. I used body filler (Bondo) to smooth out any small imperfections. I used a metal rust preventative spray paint to give it a nice finish.
Hopefully this was helpful. I posted up a template for do it yourself modders so please do not try and sell these. If you have any questions feel free to shoot me a pm or ask.
