2000 Jeep WJ - Towbar

[psychoR1]

I am putting a towbar and electrics on my 4.7 Grand Cherokee and there is a purpose made plug in the NSR rear quarter panel but of course I dont have the purpose made loom to plug into it.
There are 11 wired connections in the 20 pin plug - does anyone have a wiring diagram for these?

Update - figured it out - chopped the plug off and wired directly - works fine but only used 6 wires.
