I'm in the middle of replacing my front oxygen sensor of my 850T. I got the old sensor out with no problem but I can't get the wiring harness disconnected. I've managed to dismount the whole coupler from its steel mount, but cant free the old sensor. Does anyone have any suggestions or know of anywhere i could find more info?

Thanks so much

Thad

 

The red tab needs to be pulled out for it to come loose.

 

Thanks for the reply. I was able to get it unclipped and switched out despite only having space for 1 hand.
PITA!

 

Yes it is a pain I did one friday at work. But I can work both hands up there but they look like pretzels!!! LOL
