I am doubling check if this is correct. I want to recharge my A/C and I am looking for the low side port. The High side port in on the front passenger side by the radiator. It has a black cap. I found a port labeled "Evaporator Service Port" located on the drivers side firewall. It has a green cap. It not next to the accumulator which is on the firewall but on the passengers side. Is the Evaporator Service Port my low side port.

No. It is the evaporative emissions service port (funny, that's what it says on the tag).

Look on the side of the accumulator can, on the firewall, under a ton of crap for the low side port.
