Need Help: Identify these plugs
Somebody tell me what these plugs used to go to on my 84. They where danglin down behind the motor on the tranny. I'm thinking one or both went to the lockup converter? Which someone before me replaced the TH350C with regular old th350, Along with the esc distributor for a non esc HEI, The plug for it was a danglin' too. THese are the only two plugs that weren't connected to anything that I couldn't readily identify what they are for. I guess I need to get me a manual.

The round plug looks like a kock sensor plug with is not needed since the ESC dizzy is absent. My truck had the sensor on the passenger side about the middle of the block. The four prong plug would be to the transmission, again not needed.

the knock sensor has one large round hole in the middle, and two places that grab the sensor on the sides. The one on the left looks like it went to the oil pressure sender that would have gone behind the distrubutor on that year. I think the trucks with gauges had 2 prongs like that one, and the trucks with lights had one prong, IIRC. The other plug does indeed go to the trans for the lockup converter.
