Yep, a long arm helps but if you stand on something 6-8" tall it helps a lot. The connectors are kinda peculiar until you see how they work. You pull up on a gate like device that does not come off the connector. You may need to pry it a little with a small screwdriver to get it started. Once it's all way up, the o2 sensor end of the connector will unplug. The two connectors are also mounted on a standoff. Removing them from the standoff will give you some slack.
