...which will require cutting/splicing the OE harness - something most people will NOT want to do for one reason or another.

To the OP - White spots on the bottom of the coils mean NOTHING.
Nothing at all.

The only real test of the coils is resistance/inductance across the ignitor (the FSM has the specs) and using a timing light on the coil wires and look for misfires, which can be done free-revving, though it is better to check under load.
