Can anyone tell me where the three electrical connectors which are clustered for plugging in a wiring harness are suppose to connect?  I have no desire to track down a new harness, given that once you start down that path, every day's a new harness hunt.

Bought my Samurai from Jonnie Meathead who was wire-cutter loco leaving me to deal with a lot of bubble gum & bailing wire, neatly wrapped in band aids naturally.

There is a 4th connector which is the positive lead going to the pos. battery terminal.

I hope that this helps!
