Answer 1

oil pressure sensor mabey

Answer 2

aftermarket ignition coil maybe.

Answer 3

Can't answer without seeing the actual device and exactly where on the engine it was mounted.  Shoot a picture, ask again.

Answer 4

Nice description-appears to be a 300-Ohm to 75-Ohm matching transformer for Television input, based on your info- why it would be in the motor compartment is a guess. I thought at first it was a capacitor to block spark-plug noise from your radio etc.

Answer 5

Post a picture and I can tell you what it is.

Answer 6

There is nothing original to that truck that matches that description.

I'm with stephen d, it sounds like a transformer for a television. You didn't say what size it is, or if it is "hooked up" or just loose on the motor.

On a 30 year old truck, you might find most anything someone has plugged a vacuum line with, or used as a wedge or something. If it works without it, leave it alone. If not, post a picture or show a mechanic the part.
