Finished my second 12v to 24v conversion!

Finally finished my second mod, my first one was a range rover and this one is a toyota tundra i got for 20 bucks. Its an old power wheels model but I honestly think it is far superior than the new ones. Its much more solid, bulkier and spacious. The electric harness seems better quality too, every LED light kept working with the exception of one, the switches feel sturdier and the cables seem better quality.

I decided that for this mod I was going to go all out, I was going to break it down completely paint it, re wire the harness so it works with a 24 volt drill battery, change the motors and connect the bar light directly into my 12 volt circuit (originally it operates with batteries).

It definitely was a longer project but from what I learned here are my suggestions.

  1. Buy good quality connectors for both thicker and smaller cables. I think the biggest pain was cables getting constantly disconnected when applied the minimal amount of force
  2. Get a heat gun and heat shrink tubing
  3. Get a multimeter so you can see that the voltage is being properly set
  4. Get a 12v working battery and plug it in directly so you can see what is working in terms of lights, stereo, speakers, etc
  5. Take before and after pictures so you can reference how things were plugged in
  6. the 24 to 12 volt converter doesnt have to live in the console, for this build i placed beneath the seat and just carried it through with a longer cable.
  7. Get good cables that are not too thick. 24volts you definitely want something sturdy bot dont go over kill because it will be an issue to tie some of these to the existing harness.

I am adding the links to some of the things i bought

I will try to map the circuit as best as I can

Installing the new harness into my painted car the control unit, 24vto12v converter and drill battery harness are bolted to the vehicle.
