    COP - Coil over Plug Question

    This is from my other thread. It merits its own thread however, since no one in the Seville forum could answer it.

    This question concerns the COP unit that bolts into the valve covers, for example my 2000 Seville SLS Northstar

    On the right side of the COP unit, the wire harness plugs into some type of electronic box, that is mounted into the COP unit. Two screws and it pulls out of the COP unit. It has heat sinks on it and an internal plug that mates with a plug inside the COP unit. Slides in and out on guide rails.

    What is this Box? Are they propriatary to each side of the Engine? In other words can you switch the COP units front to back, with out switching out this box, or is the box a control module for the cyclinders on that side of the engine only.

    The device you mention is not specific to either side or certain cylinders....It can be used on either side to my knowlege.
