It is a little bit bigger than a nine volt battery and is made out of black plastic. One one end it has a small red led light and a small hole that has a flat head screw in it. It has 4 wires. red,black,white,viliot. It has a round NX emblem on it.
I bought a used NX kit with gen2 and bottle opener. Please help, Alan

 

Sounds like the fairly new Electronic Full throttle switch.
easier way to activate it at FT instead of rigging up a bracket and normal switch.

 

The kit was bought in dec. of last year if that helps. Most of the stuff was still in the plastic. All that was open was the bottle heater. I am clueless on this one. I have looked at the NX website and have not seen any pics that look like it. I will look again though. thanks. anymore ideas? Alan

 

Part# 15961 Throttle postion activation switch. If you need an install sheet I can scan mine for ya.

 

Steve Thanks. U guys must be right. I think I got an even greater deal on my NX kit now. He did not say anything about this switch when I bought the kit. I would greatly apricate a copy of the instructions. Thanks Alan Alan566@hotmail.com

 

you have mail, hope you can deal with a .zip file.
