New to this forum and ATV's. Hope this is still active. I have a 2007 Sportsman 500 X2 EFI. Previous owner bypassed some fuses and now I am unsure of the proper wiring at the fuse block. Also missing a fuse leg connector opposite the main hot wire which. Could you please provide the proper wiring and any tips to replace the connector opposite the hot wire in the main so I can return this to original. Hoping Lateburd is still watching this.

You have a real problem child - the 07 500 EFI did not have a fuse box - instead it used a SSCB (Solid State Circuit Breaker) module.

What is the VIN of the unit you are working on?

Apologies for the delayed response. As best I can tell it is: 4XATN50A57A969048 which shows to be the model I stated in my post on polaris website. I suppose there could be some part swapping going on here?

You have model A07TN50AU (SPORTSMAN 500/550 X2) which has no fuse box - in place of the fuse box was a 'control module'.

Here's the wiring to the control module

Here's the functions of the SSCB

Armed with this information, you may reverse engineer the abortion you have and put it back the way it was from the factory, or make the needed repairs to restore the functions you are missing.

Thanks for sharing your knowledge. Appreciate that you and others on this forum are so forthcoming with information. I assume this was done to bypass some issue (maybe with the SSCB). Is there any harm in leaving as-is? The machine started and ran before and does again after cleaning up the splice (this is what led me to find the fuse block). As you surmised, there are indicators on the display that do not work (fuel, speedo) but may cut my losses and keep on trucking if no harm. My apologies if this is obvious, just not familiar with the circuit breaker function.

The SSCB performed many functions - primarily battery charging and accessory circuit protection as well as cooling system fan and hot lamp control. If it works as currently wired, go ahead and use it, just check things to assure they work - the battery charges at no more than 14.8v - the fan cycles on and off etc.

This is for lateburd. I'm working on an accessory wiring problem and would also like the 2008 Sportsman HO EFI manual if able. 4XAMN50A58A271285 VIN. Thanks in advance. Not sure how to send PM.

No problem - I got you covered and sent the link to your email address

This is definitely an older post but stumbled across it in my research to try and fix my four wheeler.
2008 sportsman 500 ho carb, bike ran great until it lost power. I have traced voltage all the way up to the ecm and out of the ecm. No voltage to fuse block located under the steering head, no power located at the key switch or kill switch. Is this signs of a bad ecm or is there an inline disruption in this side of the harness? Really hoping someone can point me in the right direction.

Not sure what you are referring to as the ecm - the Sure Power Unit (SSCB or control module) has battery voltage on the red wire going in and should have 12v on the orange wire coming out going to the key switch - if no power on the orange wire at the key switch, replace the SSCB.

I’ve traced 12v all the way to the key switch. When I turn the key switch nothing comes on. Could the speedo be preventing unit from starting? I’m sure being the most easy thing it could be the key switch??

Unplug the key switch and jump the orange wire to the red/blk wire - if that lights things up replace the key switch
