Can anyone give me a hint at undoing the safety catch or lock on the electrical connector for the oil level sensor on the M113 (and M112) so I can unplug it? It's located in an area that's almost impossible to reach and to see; so I can't tell how it's secured. I need to remedy an oil leak, and have to remove the sensor to replace the o-ring and/or the sensor itself. I don't want to break the connector in trying to remove it.

TIA! DUTCH

I believe the release is on the top of the connector, you would squeeze it in a vertical direction (top to bottom) and pull out while squeezing it.

Thanks Gilly. I'll look again. I put a dental mirror up there and couldn't see anything that looked like a catch, but the connector looks like it's a side pull to remove.

I have a new level sensor on its way. Maybe the new part will give me a hint, at least if the catch is on the sensor itself as opposed to the connector.

With the delay, the oil has certainly had plenty of time to drain well out of the block.
