It looks to me like the 2 red wires are going through yur motor overload contacts. These wires need to be hooked up in series with the coil wires, so if the overload trips out it will not let the coil on the starter kick in. so from t2 there needs to be a wire to the pressure switch, from the other side of the pressure switch it hooks to the red wire that is loose on one end. Now from t3 there needs to be a wire the same size as the two existing red ones to the other side of the coil wire, I believe this terminal to be on the top right corner of the starter but NOT visible in the picture. Terminals 13 and 14? are just an auxiliary set of contacts and not used in this application. Now the feed goes to terminals L1 and L2 as was stated earlier. The motor leads connect to T2 and T3. When you press in the button on the cover of the starter box it will press the contacts together completing the circuit from L1 to T1 and L2 to T2. Also energizing the wires fromT2 to the motor overload contacts, through the contacts through the pressure switch(assuming it is calling for the need for power), and to the latching coil in the Starter. It will also complete the circuit from T2 to the other side fo the coil. This is assuming that there is a pushbutton on the case to depress the starter initially. If there is no push button, then the red wire that is not connected on one end should hook to one side of the pressure switch. The other side of the pressure switch will hook to L3. Now there will need to be a wire from L2 to the other terminal on the coil, which I believe to be on the upper right hand corner, but not in the picture. With this setup you will need a disconnect in sight of and within 50 foot of the compressor for sure.

If you could take some pictures of the sides of the starter it would help. Clear as mud now? Greg

The pressure switch itself had a cut off on it and the sub-panel and breaker for the compressor is 3' away. Do you think I need a disconnect also? Here are the pictures of the sides of the starter. Also there is another of the overload. The flash on the camera tends to bleach the picture. The right side of it has the letters NC on it with the numbers 95 and 96 on it.

No disconnect neededif the panel is only 3' away. I cannot see on this but I believe the other terminal to your coil is on the upper right corner, to the right of L1, L2,L3, but below 14. About in the same location of where the short red wire goes. I don't see anything on the labels that lead me in a different direction. George March is correct in that it is a 3 phase starter, however T1, T2, T3 are all motor leads and not a coil terminal, just as L1, L2, L3 are all input leads for 3 phase power. Gotta go to work now, but try and get me a pic of the top right looking down from the top and this will verify how wrong or right I am.

Looking at the top of the switch under L1 there is A1 which is one side of the coil and below 13 and 14 is A2 which is the other side of the coil.

I expected the switch was made so it could either be used for single phase or three phase.

Maybe you can see the labels better with these pictures.
