OBD1 Code Reader
Where exactly is the plug in pigtail for the code reader on a 1990 rANGER 4.0 4WD AUTOMATIC. i JUST ORDERERd a Innova reader from amazon. All the guidance/info on use would be appreciated thanks Jim Senn Athol Idaho
OBD1 plug in is always in the engine bay
In 1990 Ranger it "should be" clipped to the engine bay fuse box on one end and have a cover that says "EEC connector"
But it is always on the computers main wiring harness, which usually goes to fuse box, lol
If previous owner has used it it may not have been put back
Drawing of location of the C198 and C199 connector placement here: https://ww2-secure.justanswer.com/up...6_scan0001.jpg
At the end of fuse box, they are just held in with plastic tabs so not hard to pull out, they ARE NOT connected to anything in the fuse box, it's just a holder for them
Main Connector has an odd shape so not hard to spot: https://www.460ford.com/attachments/...est-jpg.79617/

If you ordered an Innova brand reader, please post it's model number.
While looking for it, give a glance at what they have to say re connections.
I'd be interested if a code reader for a "flash car" is even available. My experience is limited to another make where no "reader" is available for its flash system.
Also, the only predecessor to OBDII I've ever seen was OBDI used on some GM vehicles which was only good for ABS and transmission codes.
The nascent GM system did use the JWS 1961 style plug.
I am no authority on the subject. I'm just giving you what I know.

I had an '81 GM (Corvette). The OBD1 connector was under the ashtray. Stick a screwdriver in a slot to ground one pin and you could read flash codes. Also could plug in a reader for real time data. The computer controlled the carburetor jets for correct air-fuel ratio, controlled the lockup torque convertor, and one or two other things.
I also had an 85 Ford (TBird) with EFI. OBD1 codes were read by connecting a voltmeter, grounding a connection and counting the sweeps on the meter.

The Innova Code Reader Model # is 3145. Its for Fords only. I got it on Amazon. I haven,t used it yet The book seems very thorough/confusing. If it turns out to provide good info I will buy the same thing only for GM for my 1989 4.3 S-10 4x4. Will post my findings when wx improves. Jim
