OK, I feel like an idiot - how do I unhook the wire on the UVC connector on the outside of the valve cover. I am planning on checking the glow plugs (hard start/run rough when cold) and I can't figure it out. I don't want to break it either.

Thanks All

 

You wanna test the glow plugs without taking them out?

 

Yep- Between connector point and ground should be less then 5 ohms, I got the connector off - all were below 1 ohm.

 

cool good job
