RX18 wiring question

Working on a KT refurbishing, using a Heng Long 2.4ghz RX / control board, but now I need to wire up the turret rotation, barrel elevation and headlight to the RX. Which wires exactly do I need?
In other words: does anyone have an exact wiring diagram for the 8 pin 'CN9' connector?

That's very helpful, thank you.
So black and red on that diagram are turret rotation, assuming red is plus. That's simple enough. Even if red isn't plus, I can easily swap the wires around in my wiring.
Brown and blue on that diagram are barrel elevation, the plus and minus there don't really matter much, I'm using an old HL elevation unit.
Leaves white and green on that diagram for headlight, with green being plus, if I read it correctly?
If someone could confirm or correct the above I would be very grateful. Don't want to mess up the electronics by misreading the diagram - like for example, not noticing that the zoomed in 8-pin hull connector is upside down to the one drawn in the RX-18.

Use these to double check your connectors, as a little reassurance that all is in order

Good luck...

That drawing really comes in handy. I've used it on numerous occasions. The only problem I've found with it was in the strobe/recoil area. My stug has no relay, so I had to kind of wing it. Got the recoil working, but the barrel led is staying on all the time. Anyone have any ideas?
