Reversible 99-01 Miata Headlight Wiring

This is just a note about wiring a 01-05 Mazda Miata Headlamp into an older 99-00 body. It's not necessary to cut the 99-00 wiring harness. In the pic, you'll notice I crimped a flat spade connector onto 01 wiring, applied heat shrink to cover any bare electrical areas, and then slid them right into the 99-00 wiring harness. That way, I could easily play with the wiring in case I had mixed the wires up.

The wiring colors in the pic above are from an aftermarket HID kit, so please do not use those colors as a reference.
