    How do you remove the ignition coil wire connectors? OBD1 325i

    I'm replacing my ignition coils. The coils I have are not the ones meant for this car. I believe they are for an e46 because the pins going into the ignition coils themselves are in a triangle shape instead of across in a line. Similar to this picture:

    In any case they are the type that push into the spark plug wells, and I want the kind that bolt in. If I buy oem or similar coils they will not fit my wire harness because of the connectors on the end of the wires.

    So I'm wondering how I can swap out the connectors without cutting and splicing anything? Is there a tool to push the pins out?

    Also, I think I already know the answer but it's worth asking: Is it easier to just swap out the harness?
    I found somebody selling one on ebay with the correct connectors on it. Can the wires pull out from that long skinny plastic piece on the fuel injector side of the wires?
    Is that maybe a cleaner way to do it? Based on this picture it looks like I would have to splice into the main engine wire harness which I definitely don't want to do.

    If only you had an M52, the ignition harness has a main sub connector. The link below is for your OBD1 car. You will need someone to do a good job and solder the wires and use doubled up shrink tubing. Someone who is not a moron and understands where the wires go.

    So you got your car like that with e46 harneess spliced in?

    I hope that bottom picture is not of your car with the pinched burnt wire.

    Great ebay find. thank you. so yes that picture is of my car. i didn't notice that wire but you might be right. im not sure if its burned or a shadow. ill check it out next time i go to the garage.
    I can solder, I'm a technician by trade. I was just hoping there was a way to avoid that.

    Do you don't think I could just swap out the connectors on the ignition coil side? I found this video and the part number for just the connectors.
    I know it's not the same harness in the video but I was hoping I could just push out the wires from the connect instead of all that splicing.

    Another option would be if I could find better coils than what I have that use this connector that I have on here now, but I haven't found any that actually bolt on.

    Right now your idea seems like the most feasible. Just tedious.

    I found this also on rockauto. if that wire is actually burned, it might be better to get one of these so that im not splicing so close to the connector on a tight 90 degree bend. it looks like i would have to take out the fuel rail to get access to this piece. can't come out through the top. need to disconnect the fuel injector, remove it and then pull the connector out through the bottom.

    You buy the coils that match the engine. Not use coils that can't bolt or fit then cut up a harness to fit the wrong part.

    The coils you have are made to be held by the m54 valve cover, the coils you have are meant to be bolted to a m50/m50/m50tu/m52 valve covers. Any m54 or m52tu valve cover will not bolt onto a e36 engine. Just get the right coils.
