A couple wiring questions (should be easy to answer)

[SolaraOnBronze]

Okay, so I have searched around a lot but havent been able to find the answer. I had a ton of starting issues on my SR20 93 hatch and narrowed it down to a fried ecu and a possible break in the lower harness. I had a friend who knows a lot about 240s help me pull the lower harness and I checked it out for breaks, rewrapped it nice, etc.

When it came time to put it back in the car, I was unsure of just a couple things. He has been busy lately and hasnt been able to come out to give me a hand, so i thought I would ask here. My questions are:

Alternator: There is a hole on the side of it that something plugs into- can anyone show me what that plug looks like? I cant find the match anywhere.

Starter: The HUGE wire that connects to the positive terminal on the battery runs to the starter on the other end, correct? Do two wires connect to the positive terminal on the starter, or just the one mentioned above?

If anyone has a pic of their starter wiring or the plug that goes into the alternator I would appreciate it. I apologize for making this thread if the answer is out here somewhere already, i have searched a lot but havent found an answer. A diagram or labeled picture of the lower harness would help as well. Thanks in advance, just thought I would try to beat my friend to coming over and try to crank it on my own.

Excuse my nissan ignorance, toyota guy
