It in on the right side (passenger) between the side and air filter. There are two pieces. On mine, the big one is red, the small single is gray.

Thank you gatorman,,,,, I had looked for an hour and a half. It was disconnected from its mount and hiding under the fuel pump relay.

I almost lost my mind.

What do you use to red them? I suppose it’s not a standard OBD?

1983 to 2011 Rangers used two different OBD(on board diagnostics), OBD-1 thru 1994, and then OBD-2 starting in 1995
OBD 2 was required in ALL vehicles sold in the US/Canada in 1996 model year and up, and still used today

Yes, you need an OBD1 reader for 1994 and earlier, OR................you can use a test light or volt meter to read "pulses" from the computer to get the 2 digit or 3 digit Codes, this doesn't work for OBD2, only OBD1

Cool! But it semes hard to find a fair price obd1-reader where I live. There are adapters for obd2, which I already have. Does that work ok? I get the impression Ford has their own standards when I google.

OBD1 tended to be Car Maker specific, OBD2 has generic codes that all car makers were required to use, but there are car maker specific codes in OBD2 as well, P0xxx is generic, P1xxx is car maker specific

No adapter, best to just count the pulses to get the codes for free on OBD1

Go here: https://www.therangerstation.com/tech_library/index-charging-ignition.shtml

Look at EEC-IV diagnostics fist

There are also the Ford code lists, 2 and 3 digit, which is year specific

Here's another link on code reading. Just use a testlight, you should have one in your toolbox. Go buy one if you don't, you need it for other things and you should learn how to use it.
