Chinese Scooter and Go kart Parts, Repairs & Upgrades made easy!
Here ya go. Hope this helps others. This is the pin out and color code on the stock CDI box for my 2012 Trailmaster XRX 300.
I just cut off the factory plug from both the cart and the Tuneable CDI I got from KNM, then soldered the two sets of wires together. Fired right up.
AC fired CDI Pinouts
While cranking the motor (with DC, you only need your key to be in the "on" position), place your meter on "AC volts" then Connect your black multi-meter lead to the black ground wire at the coil wire, and with the red lead to the lighter color on your Coil wire. (Usually Green or Blue but it varies) and check your voltage output.
CDI output Can be 5% to 30% less than the output from the stator.
The minimum is around 16-18vAC.

Here is a short install video.
This procedure is the same for all of our Digital CDI's, in any machine.
USING THE TOGGLE & ANTI-THEFT-
When hooking the included toggle switch directly to your battery, the Toggle switch must be in the "ON" position in order for your bike to start and should be turned off when you are not riding.
This serves as an excellent anti-theft decice when you hide the switch under your seat or some other inconspicuous place.
If you do not need or want the anti-theft feature, you can omit the toggle switch and hook the red wire directly to your hot wire on your key switch. This will result in a standard key operation but you'll lose the anti-theft feature.
More Power, better reliability, better gas mileage, more RPM's and less emissions.
