No power to ac wiring

So just like the title says im trying to get my ac back working since po took it all out but all wiring was untouched thank god. Ok so here is the situation the blower works just fine on all speeds which is great had to wire in the blower hi/low relay though. So when i take a test light key on am i suppose to have power at the ac compressor connector, hi cut out switch and low cut switch im not to great with wiring. is this a task i can get to work again or should i send it out to be rewired so i can have ac again ????

Using a voltmeter or test light (the type for testing for voltage, not a continuity tester) probe the light green wire on the pressure cycling switch located on the accumulator (the silver can on the firewall).

Is there power there when the key is in the RUN position and the AC controls are set to AC?


Happy Racing !
