The wiring diagram for my car shows an item called a "Ground Connector Sleeve" its designated as Z6/1. Basically one of my coolant sensor wires first goes through this sleeve, and than continues to chassis ground.

The reason I am asking is that I had to run a new wire, but I ran it straight to chassis ground, bypassing that "ground connector sleeve".

I did that, since I don't know where this "ground connector sleeve is located", nor do I know what it is, or what it does. Does anyone know?

Thanks

Phil
