I pulled the motor out of my 99 and I'm installing another 99 motor. This wire was not connected to anything on my motor, but it looks like it was pulled out. The plug is bundled with the aic and what not. It's the very top plug.

is it me or is that a three conductor molded wire? if so, the only one you should have is for the block heater (does it go down to the side of the block under the exhaust manifold?) in which case it would have a standard 3 prong 120V plug end on it. replacement cords are available from just about any parts store.

 

It is a 3 wire plug but my block heater is after market and the wire comes straight from the heater itself and out through the grill it doesn't run with any other wires.
