The outdoor unit should have 2 small wires connected to the contactor coil. This delivers the 24v "Signal" to energize the coil. The wire from the t'stat for cooling are usually yellow, in almost every case. When you put the t'stat in the cooling mode and set the temp lower than the room temp, the indoor and outdoor unit should come on. Check for voltage on the terminal block for 24 volts accross the yellow and common wire. Common could be ground on some handlers. If you have the 24 volts, then check for 24v on the 2 small wires (usually 18 to 22 gage wire) on the contactor coil. If no voltage, trace the 2 wires back to the indoor unit and see where they go. If they are the ones that are not attached, put one on the yellow wire terminal and the other on the common terminal. This will send power to the indoor unit and then piggyback to the outdoor unit. Do not remove the yellow and common from the terminal block. Don't be too concerned about the colors from the outdoor coil wires. Just make sure they are hooked up right. Good Luck and hope this gets it going.
