Help with electronic choke

I just picked up a 1986 b2000 the guy had a manual choke hooked up.
and the electric choke is not connected. Where does the electric choke connect the wire is yellow with a red stripe I think I can't find any empty plugs on the harness. also picttures would help alot

It plugs into the rear of the alternator, believe it or not!
My wire was missing or just short coming off the carb choke heater, so I added my own wire and terminal to the end and plugged it into the alternator like it should be.......here's a couple of pics.







The correct terminal connector is white/clear looking and it has the locking tab on it that you press/push to unplug it from the alternator.

Earl is the man!

There is already a wire pluged into the alternator. The wire is red with a blue stripe and a white plug that comes out of the harness. Do I unplug the red wire and install the choke wire into the alternator or is there somewhere else in the harness with a plug end to connect to?
