So the obvious solution to the inadequate wiring in the Kid Trax Bronco, is a full replacement. I could have done something simple like upgraded wiring and switches, but instead i decided to go all out, and use ML Toy's Electronic Speed Control.
This thing is pretty cool. its a full variable speed ESC (so full variable speed control), with a brake pedal as well. Its programmed to apply the brakes after a certain amount of time if it doesnt see either pedal input, so you cant have a car runaway down a hill, which i think is a nice safety feature. It also has a 12v output for powering the stock headlights & radio, which we'll be using as well.
In addition to this, i am adding their key switch, and digital voltmeter.
The meter is not necessary, i just want it for the convenience of knowing battery life. The key switch i do want though; Power Wheels have the batteries under the hood where you unplug them to charge them, but Kid Trax has them hidden in the back under the seat, with a charging port. Having a key switch means we can turn it on/off to charge without having to unplug the batteries every time.
So lets get that wiring harness out:
With the track removed the harness is exposed:
Foot pedal wiring:
Remove a couple screws and the steering wheel and dash comes out:
power plug for dash harness:
...and the chassis harness is removed:
Here's the plug for the horn pad, which we'll obviously reuse
...and this mess of wires is the backside of the directional switch, where Kid Trax tapped off for all their other 'key hot' accessories, such as the horn, radio & headlights. We're gonna reuse some of this, but not all:
Just give it a slight tug and the volume knob pops off to expose the jam nut to remove the dial:
This is about as far as we need to go, as far as disassembly is concerned. Tomorrow we'll staart installing the new harness and ESC!
