AC Relay question..pls help..its hot here in FL still

Hello to the boards and have already learned a ton! Hoping someone can help me out. I just bought a 93 Mustang LX Coupe that the previous owner installed a crate motor 306 in. Before doing so, he took everything out of the engine compartment, sand blasted it...etc...the right way. All AC was said to be working at the time everything was pulled. When I turn on the air, the blower motor comes on, but the AC clutch does not engage. I replaced the clutch cycling switch and toped off the R134 so the pressure is good (around 55 at 90 degrees) . I can get the ac to run cold when I jumper wire the positive side of the compressor. I then figured it was the AC relay. I purchased on from Pepboys...but cannot locate the relay ANYWHERE. There are no wires in the passenger fender anywhere (I even pulled the fender well back. I cant find it on the drivers side, or under the dash or behind the kick pannels anywhere. I did notice that there are 3 unconnected/unused connectors coming off the harness by the condensor. Could it be that there is a missing harness that plugs into one or all of these? ANY help at all...including PHOTOS would be greatly appreciated!!! Thanks again to all for the warm welcome to the boards. Ron

PS...even just a photo of the relay and what the wires look like and where the lead to would really help....
