It probably has a pigtail in the box (hopefully) so that you can plug the coil into the factory wiring harness. If that coil is too wide for the mounting bracket that will present a problem. I made a bracket for one of these coils, and that was a PITA. Honestly it would be easier to return the Accel coil and buy an MSD or a Delco one. Either of those will mount to the bracket without issue and will plug right in.
This is a picture of the MSD 5526:

Compare this to what your Accel coil looks like. Those two connector plugs on the MSD are not on the Accel which is why you need the pigtail. An AC Delco will also do the job just fine for a 4 cylider, and will mount up and plug in without any hassle.
