Five wire throttle to six wire controller

The throttle has a switch (with a key, which is kinda cool but I could live without it), and 5 wires:
  • red
  • yellow
  • green
  • black
  • blue


The controller has 6 wires:
  • red
  • yellow
  • green
  • black
  • white
  • brown

Thoughts on how I should work this out? I've got a multimeter here. What's extra annoying is that I thought the throttle had a white wire in the photos online, but it turns out to just be a thread running along with the wires.

Switch is the ignition for controller, it expects battery voltage in one wire and battery voltage out in another wire depending on switch position, so that's 2 for the throttle. Last 3 are standard throttle wires, 4.5-5v, signal (return), ground.

Controller will have throttle and maybe 1 input for ignition ignition wire is thinner. Battery wires should be thicker. If it doesn't turn on just via battery (it will still spark when you connect even if ignition is required and is off, so not starting) then you need to connect one wire to ignition. You have to be careful there because putting battery voltage on any sensor wire or +5v, GND line will start frying things.

What features did the original throttle have?

It had a 3-light battery gauge, for full, medium and low battery. That died, which is why I'm replacing it, having no idea of the voltage is giving me anxiety.

The new one has an LED battery gauge.

That's exactly what worries me about this. I've fried lipos before, and this one was pretty expensive.

If you can't find wiring diagrams for your throttle and controller, this thread will provide information on how to sort them out.
This will probably require opening up your controller to look at the PCB board labels, and perhaps open the throttle to check it's connections...
Do not depend on wire colors entirely unless specified by the manufactures!
