    I see what youíre saying now.

    The other two wire thing (besides injectors and coil plugs) is the heated pcv (which lives on the passenger valve cover, similar connector though) which is white-orange & red-yellow.

    My PCV Is definitely not heated, that must have come about later. It sure looks like a knock sensor connector.

The parts system at work shows a dual knock sensor with a totally different connector. I'm reading that that's only for the Marauder. So I'm guessing maybe the wiring harness is compatible with another vehicle that had the knock sensor? Either way it doesn't seem like anything is missing.

    Looking through my 2008 evtm connector views, the only thing that comes close is the knock sensor connector and the cylinder head temp sensor connector, keying does not match. If they did replace the engine, the question is what engine is in it and what year it came from if they kept the engine harness with it.

    Can you make out what the wire colors are?
    Well I know it's a PI engine but that's all I know for sure. I believe the wires were brown and yellow, either that or black and yellow. I'll look again when I get the chance.

    I seem to remember an extra connector on my 93 (i know it's not the same) MGM injector harness.
    Like GM guy said, wire colors and a wiring diagram will be a huge help.

    I suppose that could be it, the check engine light isn't on so I assumed it was something extra. I don't know where the engine in this car came from but I'm 90% sure it's not original. When I changed the starter I noticed the passenger side of the block is marked 03/19/19 in white paint. I bought the car in February 2020 with 95,000 on it from a local car lot. From what I've found it was sold new in Florida and spent the rest of it's life in Northeast Ohio about 80 miles from where I found it. All 8 plugs looked great and at 5,000 mile oil change intervals the oil is still very clean. I do have a receipt saying the entire engine was re gasketed by a Ford dealer in Cleveland Ohio in March of 2019 at a cost of $4200! That all seems a bit fishy, who puts that kind of money into a 17 year old car and why would a 70,000 mile 4.6 need that kind of work? I have almost $30,000 worth of receipts between 2015 and 2019 from that same dealer. I'm thinking whoever owned the car before me was a bit impressionable and said dealer had no morals.

    Edit: I don't know how true it is but according to what I read on CVN the knock sensor didn't come out until '03 on the Panther 4.6. The parts system at work shows a dual knock sensor with a totally different connector. I'm reading that that's only for the Marauder.

    started a topic Mystery connector?

    Mystery connector?

    I found this two wire plug the other night when I was changing spark plugs on the '02 Grand Marquis. It's coming up from somewhere below the alternator between the rear of the alternator and the bracket. Anybody know what it is? I'm guessing it's for something I don't have, Police alternator maybe? The wires are pretty frayed and I don't believe it was connected prior to the plug swap.
