Wiring diagram for 1985 J50 harness

[Stevolibido]

Hello all,
Just purchased a 1985 J50BECOB with harness. I know what some of the wires are but not all. I've ordered a service manual which hasn't arrived, thought I'd get a head start.
can anyone provide a harness diagram or listing of what each wire is?
Thank you very much for your help.

Hello All
Thanks for the referral to MaxRules, they don't have the j50 diagram. Here is what I have figured out from the harness, there are 7 wires:
Black - kill switch
Black w/ yellow stripe - kill switch
Yellow w/ red stripe - ignition
Red - battery
Purple w/ white stripe - choke
Purple - ?
Brown - ?
Grey - ?
On the dash end of the harness is a buzzer that the solid purple and brown wires go to. The purple splits off the buzzer and goes to the accessories post on the ignition switch. The grey wire is attached to nothing.
Questions, what is this buzzer and do I need it?
What is the grey wire?
Thanks
