I have a new 2018 Giant Dirt e +1 Pro with the Yamaha PW-X motor.
I have installed lights and found it hard to find information on this, here are a few pictures and some info to help.
Choosing the correct lighting is important as the information I have seen says that this is only a .5 amp connection. I found that the Busch & Müller Lumotec IQ Premium Cyo E from Peter White Cycles works great with the Toplight Line for 6 volt E Bikes tail light. I mounted the Tail light on a Salsa Wanderlust rack and the front with the Nylon Headset Mount 1- 1/8" for threadless headset B&M471B11. Note you must raise the bars a bit for clearance.
First, you must drop the motor to get to the harness. It is in the down tube of the bike by the motor. Once you pull the harness out of the down tube you will see a big piece of shrink wrap tubing, the wires you need are loose inside of this tubing. They are the white (+6v) and gray ground. I added a plug and extended them to the bottom of the motor where i made the connections to the headlight and tail light. make sure to pull the headlight wire at this time.
I hope this helps,
