Another good reason to protect your winch circuit with a fuse and/or relay-

Braptor owner decides to go crazy while towing you with a flat strap on the sand dunes and rips your bumper out of the OEM bumper mounts Talk about making an already bad situation worse. Luckily (?) it pulled the wire cleanly off of the battery terminal and there wasn’t a severed 2G hot wire flopping around the engine bay.

Man- this sucks... I'm assuming you didn't have any reinforcement of the factory frame?? I just bought the MetalTech kit to back up my winch bumper. True to the original Bronco as well- the front frame mounts aren't good.

Not my rig, but yeah-no reinforcement on the chincey factory mounts. I have reinforcement for ours but I suppose it really doesn’t do us any good sitting in a box in the garage.

Lol, ripped the frame. I am welding in my next setup and boxing the front frame.

Yeah that was at UBB. Poor guy

We went with 500A relay basically right off the positive terminal. Was very easy to make a mount off the battery tray with some flat metal straps.

@SierraBronco I’d like to clarify the winch electrical setup. You go straight off the positive battery terminal to the 500a relay with no fuse? And then from the 500a relay to the winch with no fuse? The Stinger 500a relay doc suggests a fuse between the battery and the relay.

Looked back at @nolimits photos. I like the liquid tape on the 500a relay. I was wondering how to protect those terminals. That’s a good idea.

Sorry-it’s in the thread somewhere. We go straight to the relay then through a 500A class T fuse over to a junction box that distributes to both winches.

Ok cool. So there’s a very short run (not visible in your pic) from the battery to the relay. That correct?

That’s exactly why I deleted those factory mounts. My bumper is tied into the frame, but didn’t even think of the electrical hazards.

Yeah it’s a 90 degree terminal almost straight into another 90 degree terminal that ties on to the relay. With the size of that fuse this gave us the shortest amount of hot wire. Was going to get a spare fuse but thought about it bouncing around and breaking, so then we’d have a useless $130 fuse sitting there. Also there isn’t a diode on the relay, so it’s life is limited if frequently used. Built a jumper that will bypass relay and fuse and go from the battery straight to discharge side of fuse if we need it to get out of a bad spot. Jumper actually came in very handy this weekend for connecting positive and negative terminals together to discharge capacitors and reset everything faster when the modules started acting up on us.

Not gonna lie I stole the liquid electrical tape idea from @SierraBronco and owned it like it was my discovery, lol. Well to my non-B6G buddies anyhow. so kudos go to Sierra, not me.

And Sierra can talk better about his own setup but I marked up his photo. Maybe it makes things easier. The yellow dashed lines is the TOP of the relay. The + from battery is hidden in this view as it’s using those 90* connectors. The rest is pretty straightforward.

Can’t forget his high dollar stripper….errr, fuse.

@murphtron if it helps visualize further, here is another pic during fitment and shows a good view of the posts. Ignoring the relay bracket orientation, in that view the left brass screw is where Sierra’s hidden attachment is located. The other brass screw goes to the fuse.

Edited to add a second pic showing a crude interpretation of that hidden connection using the 2 90 degree connectors and short wire.

LOL, yes the battery should be much larger but you get the point.

I am running the MetalTech kit. Installed when I was doing my bumper, winch & intercooler upgrades.

If you don’t have any, go borrow or buy a ratcheting wrench, preferably with flex head. IIRC it was a 14mm but double check. Anyhow you will need it for the bolt you have to “loop” the top bracket around. Access is pretty tight but it can be done.

Also, I had to do some minor grinding to my OR plate (passenger side, outside). It wouldn’t quite snug up square against the back of the frame horn. I also had to drill out the hole the bolt goes through just a smidge. Maybe 15 mins of actual work but when done fit like a glove.

The kit is beefy. Love it and recommend frequently. Plus just good guys over there. Here is a video they shared that may help.

Thanks for the annotated pic. Makes sense.

And @SierraBronco I just noticed the distribution block in the upper right. Is that for grounds only? And how did you mount the fuse block (with the $$$ fuse!) to the top of the OEM fusebox?

We updated this run, so the OR plate is a direct fit.

I would shoot a quick video of installing the new OR plate on our 4D Badlands, but we loaned it to a customer why he left his 24' Ranger Raptor with us for sliders development.

I appreciate the kind words on Metal-tech 4x4; we enjoy what we do!

Yeah-that’s for grounds of the winches. Rear winch was originally grounded to the frame but when replacing the main battery harness we learned that all the grounding for the vehicle is done through to 4G wires, so we ran1/0 from the winch to that 600A block and tied both winches in to it then to the negative.

Fuse holder is just held on by double sided tape. Cleaned thoroughly then adhesion promotor added.

Ok interesting. So the ground block is tied directly back to the battery NEG. I didn’t realize that’s the equivalent of a ground! I should watch more YouTube videos
