    Wolverine X4 backup light install

    I finally got around to installing backup lights in my X4. The General has done this already and his thread is here: https://www.wolverineforums.com/foru...se-lights.html and here is my tutorial.

    Yamaha was kind enough to pre wire the X4 for reverse\backup lights. All you need to do is buy the relay\sub harness and choose a backup light.

    It's fairly simple and you'll need to purchase the following:

    YAMAHA - RELAY ASSEMBLY (G8HN-1C4T-DJ-Y52)
    Manufacturer Part#
    5DM-81950-00-00
    Item Number
    OEM115811

    YAMAHA - WIRE, SUB-LEAD
    Manufacturer Part#
    5UG-82583-00-00
    Item Number
    OEM451278

    Corsa socket terminals to convert your dummy

    https://www.corsa-technic.com/item.p...ategory_id=111

    A light for backing up. I used a cobb LED I had leftover from my previous Drone racing business. It's much easier if you use a single backup light centrally-mounted vs trying to mimic tail lights and have 1 for each side.

    Appropriate wire/connectors

    First thing you need to do is access the reverse light harness located beneath the passenger side rear quarter panel. There is a 10 mm bolt under the very back and then 5-6 allen head bolts, 1 push pin located near the door striker and then you also have to remove the door striker itself, also held on by 2 10 mm bolts. You may be able to get to the harness by removing the back 10 mm bolt and just the 3 rear allen head screws.



    Same plug with the weather plug removed which we'll convert to our backup light harness using the Corsa pins



    I used the smaller gauge female sockets on the right. I've pulled one from a Yamaha OEM accessory splitter so you can see how they install. You can see how the rubber boots install as well. I had a pin unlocking tool handy but you could use a needle should you ever need to release the female socket from the plastic plug. Wire up your backup light(s) leaving enough wire to reach the plug



    Under the hood you'll find a white 4-prong plug near the battery. That other existing relay is for my turn signal kit.



    Here it is with the plug removed. You won't reuse that plug so you can set it aside



    Here we have the Sub Lead harness plugged into the relay. You can probably get the relay cheaper but the OEM part includes the rubber holder, which is nice.



    Installed in place



    I wired up a simple LED for testing to make sure the new circuit works. Put the shifter into reverse and turn the key to 'On' (no need to start the engine). As you can see we have success. Polarity is standard for Yamaha connectors



    Nice thing about this cobb LED is it's so small but very bright and I installed it using a zip tie to my new OEM cargo box (used the existing drain hole)



    No issues seeing things behind me even in my side view mirror





    I've rotated it pointing 45 degrees down as I don't want to blind people behind me backing up. As you can see from this picture, it is BRIGHT!



    Still hard to get rid of the brightness glare even in the daytime



    Stop being jelly (jealous for you old farts) of X2 owners and get your backup light game on with your X4!

    No it doesn't. That disappointed many of us X4 owners when the X2 came out and it had integrated reverse lights on the taillights. For how much more the X4 is than the X2 I can't belive they didn't have them on it stock. At least Yamaha was decent enough though to have it most of the way pre wired for them. I am in the process of adding them to my X4 right now. I have everthing except for the sub lead. The dealership I bought that from online is slacking on shipping it.

    Would you have the part number for seals to be used with the corsa pins?

    Found it in another search.
    I know, read more, type less, lol.
    Thanks guys.

    Ok. Need some help on where I’m going wrong. Got the relays and harness. Plug into plug by the battery. Took off the rear passenger panel. As you can see in the pick, there’s a black plug which I removed the cap off. But this plug is hot with or without the relay plugged in and neutral, reverse, doesn’t matter it’s still has power. So my question is. Where do I plug the lights into, to come on when you put the ride in reverse?

    That's very interesting. I just did mine last week and the first thing I did was install the relay then closed the hood back up. I then pulled off the rear passenger fender to expose the connecter just like you are showing. I then pulled the cap off the connector and ckecked it and it was not hot. I then turned the key on and checked it again and it still wasn't hot. I clicked the shifter into reverse, checked it again and it was hot. I tried it a couple more times taking it in and out of reverse and it worked as it should so I continued the install. Something is definitely going on of your isn't working right.

    I found my rookie mistake. I was touching the hot wire with my test light but was using the Wolverine frame as the ground. This was what I was doing wrong. This is why it was hot no matter what. Got the plug done and everything is working perfectly. Thank you for the help

    Good job. Very nice X4 upgrade. I was playing with mine in a dark tunnel that passes under a freeway out on a ride today. So nice to not even have to think about hitting a toggle switch.

    Just wanted to say thanks for the thread. Thumbs up for MO, the General and everyone else that participated in this thread. I got my X4 last week and the first thing I wanted was backup lights. Ordered the parts and by following this thread it was a simple but needed upgrade.
