For those who are thinking about doing the H4 upgrade, either from Fast
Forward while David has the sale going ($430 CAD = shipping, ~$362.44 USD +
20, or ~$382.44 USD total for 86 to 91 outer lights) or elsewhere, I have
found a place that sells the male 9004 headlight plugs.

With these plugs, you can connect to your existing wiring and not have to
cut/splice your stock wiring.  I plan to solder the male 9004 connector to
the H4 connector (provided in the headlight kit) and cover the connections
with heat shrink, for a waterproof seal.

I need to do this because in North Carolina we have yearly inspections, and
most inspection stations will fail you for e-code headlights. I'm getting
another headlight mounting bracket and the two inner lights, and will mount
the H4's on this.  Then when the inspection time rolls around, I'll remove
those lights (4 screws) and remove the harness adapter, put the stock lights
in and I'm good for inspection!

The place that has the connectors is Susquehanna MotorSports.  They are
selling for $6.75 ea, total with shipping for two was $20.  A little pricey,
but these are very hard to find.  The web page for the connectors is:
