Did anyone figure out what happened here? I'm having the exact same issue on my 2010 nytro...

Does your tail light and DC plug in work? The load control relay feeds those three items. The sled will still operate without it but it controls anything that only operates while the engine is running.

I checked all fuses and relays and everything is good, still no tail lights or headlight.

If its your head light and tail light it's in the load control relay or wiring as they have there own fuses after the relay (wouldn't take both out) and its fed from the main fuse (if there was a problem with the supply nothing would work.

So it's in the load control relay or wiring.

The power is the same as your ignition so doubtful thats the problem but check for power to the red wire/terminal to verify that. It has constant power.

Then the brown should have power when ever the key is on, once again the same power it takes to make the sled run so this is doubtful.

The relay is triggered by the ECU whenever the engine is running it grounds the brown blue wire, so with the relay out you should see 12 volts between a power source and the blue brown wire. This is one of two wires that would drop all accessory power if it has a break in it.

Then there is one white wire that takes the power from the relay and feeds all three fuses (head,tail,acc) so a break in this would drop all 3 with no other symptoms as well. If you check for power at your fuses and don't have it but have checked the others first then the problem is in that wire.

Here is a picture of the relay connector so you can reference what colors where.

Ok thank you, just on my way up to work for a week so I will have to check when I get back home. Any idea where the ground would be mounted for that?

The relay is grounded through the ECU, this is what triggers the relay.

Best of luck when you get back, feel free to shoot me a email if you have any questions.
