Default Need sensor help on B16A2

I have a cold start issue with my B16A2 and recently I also have a stumble on low rpm acceleration. High rpm acceleration is fine.
I have 2 CEL codes (22 - VTEC Oil Pressure Switch and 6 - ECT Sensor (Engine Coolant Temperature)) I'm debugging and my wire colors don't match any schematics I can find on this JDM B16A2 engine.
My harness was redone for me by Rywire so I could drop this engine in my 97 Civic EX. There are two 2-pin connectors on the harness that have been labeled VTEC and one 1-pin connector labeled TW (I think that's water temp but not sure). I included a pic for reference.
Sensor 1 in pic is labeled TW and has red/yellow and black/green wires. Sensor 2 is labeled VTEC and has yellow/green wire. Sensor 3 is labeled VTEC and has yellow/black and purple/yellow wires.
The troubleshooting guide in the manual I found online talks about the 1-pin connector, yellow/green wire as belonging to the coolant temperature sending unit. But that's labeled VTEC.
I'm totally confused! Can anyone tell me which sensor is which by looking at the pic?
