As mentioned, the two on drivers side near firewall are the toughest. I found unclipping the two diagnostic plugs along with undoing hot leads to terminal post located under plastic cover located on top/front of heater valves by firewall gave me enough room to remove plugs with extensions and wobble combo. I did not have to remove brake reservoir. Other side is a lot easier. you need to remove washer reservoir tank. Careful not to brake quick release connection on plastic tank. Gets a little brittle with age.
