May need to replace the O2 sensor in a 1990 Jimmy S15 / v6/ 4.3.
Problem is connection wire at engine is near impossible to reconnect. Had to replace on on a Blazer previously - was a pain.
Any tips / suggestions on best ways to replace O2 sensor? Thanks.

There should be a wiring harness 2-3 inches away from the sensor. You don't disconnect it from the engine compartment to replace.
