Which one of the terminals in the pic is the S terminal or starter activation switch? What are the other terminals also? Is the S terminal the one that is wired to the starter? Thank you.

That spade terminal is the S terminal where I connect my remote trigger.  The top is the positive.  If I recall correctly.  Battery ground goes to the top bolt holding the starter onto the bellhousing.

 

The small flat one is the "activation" wire.  The big one at the top is where the cable from the battery's positive post connects.  Leave the bottom one as it is, it's already connected properly.  It allows power to the starter motor after the solenoid is activated.

 

By "S terminal" do you mean S at the ignition switch?  From the wiring diagram?  I believe that is the correct one.  

I'm putting in a Hot Shot Plus unit. It says to disconnect the starter activation wire (on the S terminal) from the starter solenoid. Then it says to crimp on a ring terminal to a purple wire coming from the hot shot unit. Connect that to the terminal I disconnected the starter activation wire from.

I like Terro myself.  http://www.hotshot.com/products-and-solutions/ant-roach-control/hot-shot-ant-killer-plus4.aspx

 

But maybe you mean this - http://www.painlessperformance.com/webcat/30201

 

The small spade terminal on the solenoid would be the correct one then.  You probably want a female spade terminal though, not a ring.  Some cars probably use a ring terminal but ours don't.

 

You know that you can make a remote engine bumper from a two foot piece of wire with two bare ends?

Or a long screwdriver.

Cranked a few that way. Scares the bejesus out of me though.

Thanks. I have the Painless like in the pic. It's not that painless for me though. I'm trying to make the engine bay look nice. I need hotshot for mice, also.
