That and lube it up with some silicone spray so it slides out.

08 Toyota 4Runner. 4WD vacationmobile. No enthusiasm, but it didn't leave me stranded or use any oil. Reserving judgement for now.
Just did mine. As Mike says - shoot the inner grommet with silicone then push it through(out) with a large screw driver. Odds are your engine bay / outer grommet is rotten enough to not need lube. The harness and plug just bend and snake out through the outside.
