I did a SOHC AUTO to SR 5 speed swap with a battery relocation to the rear passenger side. When I connected the neg bat terminal, I heard something like a loud fan. I then found out that the starter was spinning freely but not engaging the flywheel.
The lower wiring harness is from the AUTO SOHC and I don't know if I'm connecting the right things to the starter. There is a top post, a lower post that directly connects to the solenoid (possibly B+) and the signal spade (S terminal). On the wiring harness there is 2 female connectors that will fit on the S terminal (one has a boot and one has nothing over it). I connected the B+ to the lower post that connects directly to the solenoid and the S terminal to the connector with nothing over it.

Other than all of this my swap is ready to be primed and on the road but until I figure this out tomorrow in class I'm dead in the water so I was just wondering if anyone could chime in to a fix before I tackle this tomorrow. THANKS!!

Check to make sure you have fuel (pressure) and Spark (Plugs, Crank Angle Sensor...)

Fuel pump energizes, don't have a fuel pressure gauge so i'm not exactly sure about that and my CAS is unplugged due to the fact that I need to prime the system so i'm not getting fuel or spark intentionally. I'm only trying to figure out my starter issue here thanks tho

Ok so I got the starter wired correctly but I'm not getting any power to the signal wire through the ignition when I turn the key. I'm thinking that because I did a 5 speed swap I didn't jumper the 2 wire park neutral switch. In the write up on nico the wires seem to be black connected to a tan wire. My wires are black/yellow connected to white. On the lower trans harness, i also have a male connector that has the same wire colors. I dunno wtf is going on please someone help!!
