I have an 83 f 150, with a 4.9 liter straight 6 4x4.

Trying to figure out what computer I have and where it is located.

I'm pretty sure the motor has some issues, and need to know the procedure on how to read the codes from older computers.

thanks in advance.

There are no codes to pull off of a 1983 vehicle.

OBD1 wasn't mandated until 1988. Simple check? No CEL, no codes.

I got an 85 if the computer aint on the fire wall of fender its on the passenger side interior behind the kick panel. and you can check codes on them it just sucks really bad i have a reader for them.

johnnyrogers

yeah, i was going to say, i know my truck has at least eec II or eec III.
So it should shoot codes.
I don't have any cel lights, but then again my instrument panel/guages have not worked in a while.
I have an ignition module on my drivers side fender, and on my passenger side fender, I have an electronic regulator.
Haven't checked my passenger side kick panel yet.

you should also have a diagnostic port on the driver side of the engine compartment you can pick up a reader at the auto parts store or use a volt meter look at a haynes repair manual it tells you

by the way if you have EEC IV get rid of it cause it is the biggest headache ever made by ford

johnnyrogers

ok. I see two single plugs hanging loose. probably them. I have chiltons, it doesn't tell you squat.

EEC IV can't be worse than the older computers?

screamindemon

Oh yeah it can trust me the plug should have somewhat of a semi circle shape to it. its bigger than the other ones around it
