I need to know when the LPS is telling the condenser to turn on and off. Does anyone have a link or directions on how to attach a test lamp that will show me when this is happening? Thank you. I dont to ruin a perfectly good condenser.

you mean the AC compressor?
that is easy... on the passenger side firewall on the heater box you will see the Accumulator/Dryer...
On it is a 2-wire low pressure switch... pull that plug off and with the key either ON or in ACC test the wires... one will put power to the switch and the other wire is the switched wire... connect your lead to the switched wire.
This will tell you when the AC compressor cycles to to tripping to low pressure switch
