Ok man im gonna be honest...what have you been trying to inform me about this whole time. Maybe im just reading things wrong. First you said I didnt have an '88 harness, which you were right, I really didnt. I said after the info I received and some more researching I have an '89 harness. You tried saying that I didnt have a '89 either. Then you started telling me about some kit that you bought from Ford that came with a MAF Connector. I then again tell you that I dont need that setup because I have an '89 harness and nothing was spliced into it. You then tried telling me that more than likely someone did splice connection into the orginal harness. The reason I know my harness isnt from an '87, early '88, or Cali '88 is because the '87 and early '88 came with a 5 pin connector from the main harness to the o2 harness. The '89 main harness came with an 8 pin connector to the o2 harness. The Cali '88 came with a rectangle MAF connector instead of the oval connector like on the '89. My car has the oval connector. Your now trying to tell me that I need a code reader for the sake that there might be codes that i dont know about. I dont need a code reader. Ive been knowing for some years now that you can check the codes with a test light. Ill post up a link for you to check out. Like I said, I honestly dont know what you have been trying to "teach" me or inform me about. I guess the Mustang that is sitting in MY drive way isnt mine, it must be yours since you "know" so much more about the car that I have in my name and possession than I do. I appreciate your help on the topic ive asked about, but now you seem to be veering off the main question from what I asked. I kind of see why lilJoe07 quit responding to you.
Anyway heres the link. Dont tell me that you need a CEL because you dont. Pre '91 used a 2 digit pattern which you can read with a test light or multimeter. The post '91 will use the check engine light to read the 3 digit codes.
