Engine Swap wiring issues, Olds 307 to Chevy 355

[MikesCutlass]

I've got the motor installed and most everything figured out but I'm not 100% sure about the wiring. I was told the green wires coming from the drivers side harness is for the water temp sender but mine has two wires going ino one plug. How can I make this work on a chevrolet sending unit? Also does anyone have a schematic on this car so I know what to delete in the passenger side wiring harness? I'm wanting to keep all my A/C wires but get rid of the emmissions and other BS wiring I won't need. Oh, and on the starter. I cut and spliced the starter wires but seem to be missing a wire from the hot terminal on the starter solenoid. I have the hot cable coming from the battery, the large 10 gage wires with the fusible links coming from the ignition side and the small wire going to the smaller terminal by itself. Is this correct? On my chevrolet I had one more 10 gage wire coming from the hot terminal on the starter to the firewall. Thanks
