2007 Sportsman 500 H.O. EFI electrical

First off thanks for all the helpful threads!! Second off...I just bought A 2007 Polaris Sportsman 500 HO EFI, runs great rides nice but the previous owner flipped it and crushed the front box and head light/speedo module. The speedo doesn't work and neither do the low beams. I have removed all of the front end and looked for the mysterious fusible links to no avail. I found a wire going to the Black Box mounted under the handle bars had been cut, grey with a black stripe, 8 from the right on the top terminal of the black box. I soldered it back together but no change. If I wiggle the loom going to the headlight/speedo module the low beams come on and for a brief moment the speedo came on but flashed 12:00 and that was all. This is my first Polaris so I've got nothing as far as wiring knowledge but it starts and runs and everything works as it should with the exception of the low beams and the speedo. Any help or wiring diagrams would be great!

Thanks for the advice...I cannot find the 07 manual for a 500 HO EFI. I have the lights working now, turns out the left switch box had a bad connection at the connector. For just a few seconds the speedo light up again and flashed 12:00. Then just the Speed indicator was lit. Right now I just see the indicator (un lit) bouncing to 0 then back down about every 5-10 seconds or so. If I unplug the speed sensor cable I can see all of the icons at the bottom of the display for a few seconds, but no backlight. I'm at my wits end with this thing and I guess I'm too cheap to order the manual for 1 page of info. Anymore advice is greatly appreciated, Hell, a phone call to talk it over would be just as good. How often do the speedo's fail?

Make sure all wire s and plugs are good, speed sensor is on right front wheel , but I would double , tripple check wire and plugs cause it seems you can make them work, put some di-electric grease in plugs, may not be making good connection

Angry Still nothing

I still have not been able to find a schematic for the EFI 500. If anyone can message me something that would be great. I have one wire at the ignition switch that has 4vdc on it and i'm assuming thats not correct. All plugs are good and I've greased everyone. There has to be a pin out of this speedo some where...It's got a clock when I can get it to power up so there has to be an interface to set it like a hidden switch...Help please...
