At 180k I swapped all the coils with their OEM replacements... job, done.

Except the plastic fasteners within EACH of the six coil connectors broke on the coil harness. One of the plastic terminal jackets completely fell apart leaving the just the electrical socket exposed! After a plaintive sigh, I reckon I must harvest a replacement harness from the local LKQ. So my question...

Is the "coil harness" a sub-harness that plugs into a larger electrical harness somewhere? ...or are these six connectors merely the top of a gordian knot of meandering engine electrical harness narlyness? I can't find this specific wiring harness amongst the Honda OEM parts catalog.

If you have experience replacing this particular harness, I'd appreciate any and all advice, advisory, and recommendation you can offer.
