Hal, that just pops on or off. It's held on by compressing the foam surrounding the bars on the upper part of the fork. The wires leading to the lights should exit below the plate. If the control runs from the handlebars are passing through the front of the triple tree fork, then you need to change that so they will feed in from behind. You will need to disconnect each wire where they meet the harness and reattach them behind. Keep in mind that they should be kept in front of the head tube, but behind the top and bottom braces for the triple tree. I hope I'm explaining this without being too confusing. Let me know if I should photograph mine and post the pic.
Okay, I went and shot photos of what I was trying to explain. Hal, the "Triple Tree" is what most people call the front fork arrangement on the Whizzer. The top and bottom braces are the flat chrome pieces holding it onto the steering tube. Here are the pics.
First, here is what it looks like with the front plate on and all tidied up: http://i191.photobucket.com/albums/z21/KilroyCD/My Bikes/100_1637.jpg
I'm running two wires on each light, one goes to each light's base (mount) where it mounts to the fork. You can see them in the shot where the front plate is off. In the rear the second wire also goes to the base of the light. That's how I was able to ground them from the black wire on the harness.
