    It appears to be an oil pressure sender wire. Depending on the year of vehicle you are working on you may find 2 sender wires, (1) was for the actual oil pressure gauge and the other was for a pressure swith to keep the electric fuel pump running should the fuel pump relay go bad.

    Looks like the oil pressure switch for the electric choke. They're usually located down by the oil filter boss.

    I should have said it earlier but this is an 85. Also the second picture there is a connector in the background that I'm fairly certain is oil pressure. It's been apart for a long time and some of my labels have gone missing.

    look on your wiring diagram for a plug that has those 3 coloured wires
    then post back and tell us what it is

    Well, on the back of the intake between the distributor and the cruise control servo there is usually a sensor. If it is an idiot oil light it has a little "can" and if it is an oil pressure gauge it has a "large" can. It only has one male spade terminal on it.

    You can see the pressure gauge sender in this crappy picture. It's on a brass 45° to clear the cruise control servo.

    I can't find my diagrams. Got burnt to CD and that as good as lost. I'll find them eventually. Apparently its not needed in my case. Some of the wires were cut off long ago and taped off. I basically just shortened them this time and tucked em back in till I positively identify what they were for.

    My old oil pressure on the small block was the big can for the gauge.

    It is certainly the oil pressure switch for the electric choke, as stated above.

    Yup, Electric choke oil press sensor connector. On 85's it's up by the distributor nect to the sender for the gauge or light. The 2 sensors are on a T threaded into the port at the top of the block.

    So, If I understand correctly, I don't need it. I will be using a manual choke anyhow.

    could it be the plug in for the AC? looks like your truck used to have AC but you took it out. ill have to take a pic of one.

    it also looks like the sensor that is above the oil filter on the side of the block, but it looks to big. /forums/images/graemlins/thinking.gif

    i had the exact same connector on my 82, wasnt hooked up when i got it, just hanging under the truck. when i rebuilt the engine, since it ran fine with it hanging, i just tied it up. never had any problems with it, nor did i find out what it was.
