Hi Charles,

The Brown and Yellow wires are connected to the switch in the throttle.
You can use these to operate the eLock function of the controller, or use a separate key switch etc. if you prefer.

Unfortunately, it looks like your controller is currently programmed for a boat style throttle, which is not very helpful for a motorcycle.

You will need the USB programming cable and the PI-800 programming software to change the Throttle mode selection setting from 0:Hyperbola to 1:Linear.
If that doesn't fix the problem, try changing the Speed throttle type setting from 0:Hall effect throttle to 1:Potentiometer throttle (or vice versa).

The correct combination of the above settings should make your throttle respond as expected.

Although the thumb throttle is a Hall Sensor device, it should also work with the controller's throttle mode selection set to Potentiometer as well.

This is a relatively quick one, i'm working on connecting to a new TCMAX using the VEC300/HC3X controller and I found most of all the information I need EXCEPT what plug is that. From initial pictures I thought it was a 6pin atx-style plug but it's much smaller. Pic related.

Vec500...try turning throttle to 0-position (12 o'clock). Then e-lock off and again on. Then try to reverse. This works in my solution.

Needing to do that kind of a manoeuvre in order to brake sounds like a recipe for disaster when trying to dock in bad weather.

Hi Alan,

thanks a lot for your very detailed reply! This reply contains what I need for proceeding with this project. I will test this during the upcoming weeks and will keep you posted about the results.

I will for sure measure the cables and connections to make sure that everything will be connected correctly.

Thanks again for your help!

Best regards,
Rickard

Hi Rickard andto the forum.

The Magic Pie 5 USB programming lead is only suitable for the vector controllers (MP4 and MP5) which use a different VEC programming software (PI-800), so it is unlikely to work with your MPII controller.

The PI-300I USB programming lead is suitable for the MPIII controller which used the same programming software as the MPII (PD_282_speed).

If you are unable to get hold of the correct USB programming cable, it may be possible to adapt the 8 pin PI-300I programming lead (or the 12 pin PI-200E cable for the external controllers) to work with your MPII, but you would need to be very careful with the conversion connections as the wire colours shown below may not match your particular programming lead as the colours often vary.



If you purchase a 8 pin Mini DIN Extension lead with both male and female connectors, you should be able to cut it in half and splice it into the PI-300I or PI-200E programming cable by connecting the required four wires so that it could also be used for MPIII or external controller programming if necessary.



I would also stagger the joints in the wires similar to the diagram below even though you are only using four of the eight wires:



I recommend that you carry out a simple continuity check to determine what colour wire goes to each of the four programming pins in the connectors to confirm their correct function before trying to reconnect the four wires from the USB cable to your MPII controller harness.



The above wiring diagram should also apply to the MPII harness, but the unused Yellow wire shown is sometimes pre-wired to the throttle switch to operate the Reverse function.

I hope this helps.
