Help is needed as I'm becoming crazy frustrated, I've searched here and Google for hours trying to uncover if anyone has successfully wired led work lights to come on when you shift into reverse. I have a 2017 grizzly eps and can't find any information on how to find the source for the reverse switch on the newer model grizzly 700's any help would be appreciated. Up here in Ontario I need back up lights for plowing.

There is a thread on here about doing this. While it's not for a 2016-newer Grizzly, the premise is the same.
It's not as simple as you may think either. You have to make up your own circuitry to control a relay and turn the light bar on. This circuitry must include diodes in specific order.

In my opinion, it's just not worth it. I just simply put mine on a switch. If I want to see behind me, I flick the switch.

Thanks for the reply, while it may be a similar premise, locating and connecting to a reverse signal seems to be different from pre-16’ models and that’s where I’m having issues. all the other relays wiring and back feeding I understand I just can’t find the darn reverse signal. I pondered just running with a switch while I was pulling my hair out this afternoon but I’d really like it to be “automatic” and I’m not to fond of drilling or cutting my plastics for a switch.

I agree that finding the reverse signal to a relay is is ideal and I plan on doing the same some day.

But if I'm not able, instead of doing a switch, I'll just run a quick connect plug to near the light, and just plug the reverse light in before plowing each time and unplug when done.

If you do end up going with a switch , I just used a weatherproof toggle switch zip tied to my handlebar so I didn't have to cut my plastics.

We tried as well to find the reverse signal with no luck. Assumed there was one because the ‘R’ lights up but didn’t want to go inside there to find it. Ended up wiring it to a switch. I also did not want to drill holes anywhere so we used a piece of ABS plastic to mount the switches. I’ll take a photo during the day tomorrow but here is a night shot of the switches lit up.

I like that switch set up in the glove box! Nice and hidden, and unfortunately my handlebars are seemingly cramped with gps mounts winch toggle and handguards. I have had another idea come from a facebook page of mounting a momentary on switch in the shifter at the reverse position for a signal, going to investigate into it and see if there is a switch that would be suitable for the location and task.

OK more investigation has led me to find something that is signaled by reverse ,I need an electrical guy to tell me what’s next. The green/white stripe wire when plugged in makes the reverse light off. When I stick my test light in hooked to ground the R light on the dash turns on, if I unplug the plug in park and turn the key on my P and R are both lit up. Then when I ground it it’s back to just park... so I at least have signal now but moving forward how do I wire that into my relay. I’m not worried about having a switch right now just want it to come on in reverse any help?

My bars are also cramped, but I really like this waterproof switch from Ebay. Ive found i like the switch because sometimes I want to light up behind me when I'm not in reverse. Does both my front and back lightbars.

Edit: Just saw your last post about not wanting a switch, after I had already posted this. Oops.

HAHA no worries, I like that set up, going to try wiring this up and see what happens. Worse comes to worse I’ll be putting a switch some where.

I don’t know if I should make another thread warning people or hopefully they’ll find this thread. I did find the signal switch and traced it as far a switch I could (went right into the CDI then couldn’t trace it after) the signal does put out a 12v signal while not in reverse but after testing further before installing the relay I tested how many amps the relay needed to function, mine needed 1.5amps to actuate, I tested how many amps the signal was that came down that wire for the reverse and it was only putting out 0.01 amp. Which leads me to believe only two things could happen if it was wired up either A: it wouldn’t have had enough amperage to activate or B: it would have drawn to much amperage through the wiring and possibly short the CDI or burn a wire. I’m not very knowledgeable in the wiring department so I reluctantly put in a switch for the lights from key activated power. Hope this helps someone in the future.

Staying tuned in to see if anyone finds out how to tap in based on what you posted... in the meantime, here are the day shots on the switches

I love the hidden switch panel. Such an awesome idea!

Here are some options for switches. I think grizzrider08 used a micro switch to trigger a reverse light a while back, but I'm not sure if it was on his Grizzly or his Renegade.


https://www.amazon.com/s/ref=nb_sb_ss_i_5_12?url=search-alias%3Daps&field-keywords=micro+switch+with+roller&sprefix=micro+switch%2Caps%2C267&crid=PGE7OLTDKFWE


What kind of relay is requiring 1.5 amps to trigger? That seems like a lot.... It should be more like 15 mah at 12v, which is 0.015 amps; that's from a quick Google search - I'm not an expert. It also depends on the voltage.


I'd be really careful about tapping into triggers off the CDI, or even testing it with a regular test light as opposed to a multi-meter. Taking too much current could blow something and the CDI ain't cheap.

And to add I simply used automotive t connectors and then siliconed and shrink wrapped them when tapping into the trigger wire off the cdi.

How long has yours been tapped off the CDI wire, have you had any issues? I was concerned about tapping off it.

And did you tap into the green/white wire down behind the CVT or which wire did you T into?

I tapped into the wire up almost by the key under the front compartment, if my memory serves me correctly, I will get a picture asap. Ive had the quad hooked up this way for a little more then 2 years in the worst weather imaginable since I use it for snowplowing religiously every time it snows. The connection hasn’t failed me and the connections as of my check a month ago seemed to do great with just silicone and shrink wrap off all 3 points of the T.
