Must have for upgrading
This harness worked great for what I needed. I have used two so far to completely rebuild my kids toys. Combine these with upgraded motors, batteries and you got another couple years of life out of the slow power wheels. Some parts may need a little modification to fit but thats what you should expect. Anyone can install this. Wire lengths have been perfect.

I Do Advise
Honestly I was skeptical at first- I am no stranger to wiring in any capacity but I bought it because I know I could fix or modify anything shoddy on it - but to my surprise - this kit is pretty perfect. Perfect lengths of wires/plugs. Great price point -strong for my more custom than the average builder build would be. Anyone could install this kit, or replace a worn out kit with ease. If I could give it 10 stars- I probably would.

Soft start and faster!
Works pretty good. Does require some knowledge to install. Most of the reviews talking about it not working are inexperienced when it come to wiring and modifying power wheels. Just watch a youtube video about it. Has a built in cooling fan and the speed modes are awesome. Speed 3 increased the stock truck speed by 1.5 mph. About 15% in my case. And it has soft start so no whipping my sons head around. Which is something every stock power wheels does and my kid hates it. So double bonus.

Didnโt work with a 24v 12000mah battery.
Was not able to handle the new 24v 12000mah battery I put in it. Maybe just a bad unit. Went to power on and the on button went from bright to dim and the fan turned for a second. Asked for a replacement and will see if it was just the unit once the new one arrives. Tested the connections first without the new 24v motors I had bought too. I will update if it was just the unit. The advertisement is for 24v so I expected it to work. The unit powered on with a 12v attached. Hopefully the new unit accepts the 24v. Same thing happened with the second unit. Gonna probably have to get rid of the RC side of it or find one that will work with the 24v battery I have chosen.

Plug and play
Everything worked as it should.. the only thing it comes with the switches and peddle already plugged up and you have to unplug them to install it and they make it to where itโs almost impossible to unplug but other than that everything is great worked perfectly..

Works fantastic for most applications, however...
This is great, I used it to upgrade my daughter's jeep from 12v to 24v with upgraded motors. Everything truly is plug and play but I ran into issues with trying to replace the old components like the buttons for power, speed, pedal, forward/reverse, etc. I needed to remove the cables from them to plug them in and then reattach the cables, but it's literally impossible to remove these cables without breaking them. This made the process a whole lot harder and time consuming than it needed to be. Also, the power button was lighting red initially but then quickly stopped lighting up for some reason. Even though it still works, my kids just can't tell when it's on. I didn't give it 5 stars because of those 2 reasons.

Donโt let your lack of knowledge stop you from trying
My son wanted to upgrade his 6v corvette to 24vโฆ my response was, say less son! & here I am ordering new motors and cords based off the previous sketchy reviews on this product. Letโs take a chance My final notes: 1. It really is plug and play. Easy assembly. Take pictures before you undo the cords and try to install new buttons and foot pedals. 2. The plugs are loose fittingโฆ tighten everything. 3. The power button light does not work after three uses. So hopefully you have dashboard lights to use as reference that the power is on. 4. Use the reference video in the product description to help you figure out what could be the problem. Overall: it works and works well for the price too. I suggest you just change everything. Cords, motors.. all of it.

Works as intended
I have bought several of these for various ride on toys. They were pretty good definitely an upgrade from most stock versions.

PLEASE READ. IMPORTANT CONNECTIONS
When reading the reviews I noticed alot of complaints about the wire connections breaking when trying to pull appart. These are a safety style flat / slot connectors. You need to use plyers to release the pin then pull. So far very happy shifter cables definitely could have been longer to put back in oe fitment. Will probably redo them. Very happy so far, previously I did this review before completed install. Now that it is done I recommend this %110. It is absolutely amazing. Only issues I found was as it's a more inexpensive radio kit, lots of interference if your in an area with alot of other radio signals. Besides that everything came well placed for a very one size fits all kinda deal.

Works good
Great kit for converting most power wheels/kids ride in electric toy cars. Instructions were lacking but, it was extremely self explanatory. (if you have a good understanding for electrical. Took me a few hours to install it completely. If you want to be able to control the steering, it has the wires already there for it. But you need to buy a linear actuator separately.

Works as expected
Bought this kit to upgrade our voltztoys lifted jeep 4x4. It works as expected. The only thing I would like to see changed is the foot throttle is currently just an on/off control. But with this much power it would be nice to have speed control with the pedal. So I took care of that separately. Great kit. Handles the power no problem.
