P500 Power Steering Installation Wiring Advice

[StateLine]

I purchased the SuperATV EZ-Steer power steering kit for my 2020 Pioneer 500. This is the first upgrade that I'm going to try myself and I'm walking through the steps beforehand as I don't have a lot of mechanical experience. To prep, I've read the instructions, watched some videos (for models that weren't Pioneers), and I've read some great threads on this forum, such as Power Steering Install by Code54. But still confused on a few points.

The instructions say to connect to the white wire of the EZ-Steer harness to the white w/ black strip wire in the stock 12V AUX plug. I had a wench installed at the dealership when I bought the P500. In the picture below, am I correct in thinking that an accessory harness was used in the wench installation?

In the close-up of what I think is an additional hook-up on the accessory harness, the green and white w/ black strap wires match the wire combination found in the stock 12V AUX plug.

Would you recommend I try connecting to the accessory harness hook up or the stock 12v AUX plug? Also, do people cut off the spade connector at the end of the white wire on the EZ-Steer harness or what are you supposed to do with it?

Ya, it does look like the accessory harness was used.
Eiter will work as long as you make a good connection.
It's not the main power source, it's only used for a trigger wire.

All of the accessory harnesses that I've seen have had 4 bundles of wires coming off of them. I'd pick one of those and use as your trigger wire (as HondaSxS mentioned). All it's doing is telling your powersteering to turn on. You can do that however you like. Most go with an ignition-on wire via the accessory harness. I tied mine into my accessory power switch so I could turn it on and off for any reason I wanted.

If you want to know what wire you've got, and you have a multi-meter, or even a test light. Take a poke at it while you turn on the ignition to see what it does. Or use your tongue...

Hmmmmmm, seems someone tried that once and didn’t fancy it…..🤔 It also sounds strikingly like something she would say…..

I just did this yesterday/today. Look at my thread about an extra connector P500 - What are these 2 connectors under hood?

If you unplug the connector from the 12 volt accessory plug, the one you want to connect to is the white/black wire. That one is powered with the key/accessory power.

Thanks for the feedback! Much appreciated. Great to have a place where these kind of questions can get answered. Hopefully next weekend I can actually get the kit installed.

I didn't fully read your question(s), so to clarify, you can use any of the connections on the accessory harness, and yes, I cut the white wire to the proper length.

As for the install, on the replacement shaft u-joints note that the clamps are different sizes for the motor than for the rack/pinion or steering wheel. Also, remove the bolt in the u-joints, slide them on the shafts, then replace the bolt.

The trickiest part was getting the mounting bracket tightened down as far to the passenger side as possible to ensure clearance so the shaft doesn't hit the master cylinder. As I tightened it down it wanted to wiggle back toward the drivers side. I had my wife use a long screwdriver for leverage and apply pressure between the frame and mounting bracket until I got it tight. Someone else said they used a ratchet strap to hold it over while they tightened.

ADDED: Oh, and if you didn't already know, you can tie power to the winch block instead of running it to the battery.

Actually, I had no idea you could tie into the wench block, so thanks for sharing! I’m going to be sure to keep an eye out for movement on the bracket as I don’t want it to damage the master cylinder. Those are some good ideas for keeping it in place.

Hindsight Pro-tip - Drill a locating hole through the bracket plate and into the bar and run a self-tapper through it to hold it in place while you tighten the other bolts. If I had to do it over again (I struggled too...), this is what I would have done.

Good idea. I read someone else say they drilled and tapped a hole, and I'm not set up to tap, but never thought about a self tapping screw. 👍

How do you tie the power into the winch block? And do you have to add any extra relays or anything
