Hi all,
I hope someone may be able to shed some light on this. I have a 95XLT 2WD manufactured 4/95. On a long car trip recently, the MIL came on. I know that's a fairly common issue, and wanted to find out the specific code(s) being thrown. I was excited to learn that because I have a 95, I have the EEC-IV (OBD-I) computer, but after paying $30 for the Actron scanner and looking up the procedure in my Haynes manual, I'm not so sure. The Haynes manual is great but as you might expect from a book covering eight model years, some of the pictures aren't applicable. I can't find the EEC-IV hookup connector. Now it is entirely possible that I just missed it, but Haynes says it should be "behind the fuse box on the passenger side inner fenderwell". Well if I'm not mistaken the fusebox in my car is now in the passenger compartment on the side of the dash. I looked around in the fenderwell and didn't see anything obvious (certainly nothing labeled "EEC Test" as in the Haynes photo). Then I flipped a few pages in the manual and saw the picture for the OBD-II system, which showed a 16-pin connector right above the brake pedal in the dash. I have that connector, although my pin configuration is different (I think). On my connector, only pins 4,5,7, and 16 have metal contacts. In the Haynes picture, pins 2,4,5,7,10,13, and 16 look like they have contacts. I did some searching around here and found a couple of references to "some 1995's" having OBD-II, but how do I know for sure (aside from taking it to a dealer)? Surely there must be some big-time DIY'ers on here who are familiar with 95's. I know all 96 and later models are OBD-II and supposedly 95 and prior have OBD-I, but why would I have the OBD-II connector? However, why do I have a different pin config. from the picture in the Haynes manual? I guess I am just afraid to shell out $150 + for an OBD-II reader to find out that my truck is OBD-I after all.
I hope someone can provide some insight here. I'm at wit's end, but taking it to a dealer just seems like a cop-out.
Thanks in advance,
Dan Esmond
