Tongsheng Y Splitter. Lights. Pinout?

[dgbat2]

I ordered a tongsheng kit, installed and all's good, next I want to add lights.

I received one of these with the kit:



What is the pinout for this Y splitter? One of the pins must be the 6V lighting connection.

I consider getting a 'speed sensor extension cable' to run the cable and have a waterproof connection. I might have to get a multimeter out, problem being of course the connector is so small there is a risk of shorting or overloading something.. actually I can have the GND of the meter connected to the BATT GND somewhere else, and then just test one pin at a time, turning the light setting on and off from the display and looking for the expected value, that'd be safe.

Cheers in advance.

Green was the lighting connection.
Orange was GND.
Unusual colour choice.
