Title: Unknown plug
Post by: Hulkjoegan on July 27, 2017, 05:06:38 pm

I was following wires trying to figure out why my choke light is on, and I came across this mystery plughanging out of the wire wrap down near the oil pressure switch on the front drivers side of the engine. Single blade plug with a brown wire. Previous owner pulled out all the emissions crap so I have a couple plugs just hanging around
