Your coil is either internal or external. Typically on JDM motors they are internal but some US motors like found in the Accord can be internal as well. i.e. I have a JDM H22 and the coil is internal. On the USDM H22 the coil is external. On my motor there is no coil wire going to the distributor... instead I only have the four spark plug wires going from the distributor to the spark plugs.

Basically, at a quick glance you can tell the difference by how many wires are coming off of the distributor... if there are five then you have external and just need to trace the 5th wire(center) back to the coil... if there are only four then it is internal.
