ok so i was replacing my intake manifold gasket and when i was taking it apart i found 2 plugs in the back of the manifold that where unpluged and i dont know where they go any ideas??

anyone the plugs r black and the other one is grey

Possibly the knock sensor and there is a little resistor. Was there a little bracket on the back of the intake that goes to the block. They might attach toit. But for now thats aguess. Take some pictures.

It should be a resistor for the tach.
