1994 FORD RANGER 2.3 OBD1 TEST INTERFACE QUESTION

[chris@chriswebertreesurge]

I wanted to connect an OBD Interface to my INOVA OBD1 READER however I do not seem to have the connection for the secondary pin that goes alongside the 6 pin connector.

When I got the truck there were wires cut there by the ECC TEST interface and only 3 wires go into the 6 pin connector and there are no other connectors for the secondary connector.

I am assuming it is one of the wires coming from the ECC but I do not know which one.

Does anyone know which wire goes to the secondary pin on the INOVA OBD1 code reader?

Also IF I can identify the wire(s) can I just crimp the wire to a spade-connector and slide that onto the pin on the OBD1 reader or do I need to get the plastic female interface for it and reconnect it to the wires first?

Thanks in advance. I'll try to attach some pics later.

Thanks but I don't need the manual. The manual comes with it.

I am only interested in answers to the question I asked.

Just trying to find out if anyone knows which wire [from the ECC] that would attach to the secondary pin on the INOVA OBD1 code reader?


It is a rectangular connector that plugs in alongside the 6 PIN connector.

EEC-IV basics

I've been wanting to do a thread on EEC-IV for a while now. It's just old enough and obscure that a thread with all the relevant bits in one place should make for a nice resource. I was a Ford dealer tech starting in '86, sticking with the brand until 1999, so these systems were my bread and...

I wrote that a few years ago to outline the process of pulling codes in obd1 Fords.

The pigtail should be part of the same harness as the main connector but be aware Ford used the same connector shell for the diagnostic connector for abs and air suspension. Those don't have pigtails.

Looks like it should be a white with red or purple stripe. Likely connected to pin 48 of the PCM.

Thanks its not though its been cut off or broke off apparently so thats why I'm trying to figure out which wire it is so I can try to connect it to the reader.

Thanks! Found it, and yup its chewed right off ha ha. I found the adapter that goes to it so I'm going to butt-connect it together and see if this thing can read some codes. THANKS!!!
