I’m wanting to upgrade my taillights to led’s. I have the lights and they have 4 wires. However, my current wiring harness has round plugs that plug into the original taillights. Is it possible to order new plugs? If so, want are they called or where can I get them?

currently the only thing I know to do is cut the wires to the old tail lights and solder them to the new ones so I can keep the round plugs.

I'm planning to change my bulbs to LEDs as well. From what I've gathered, it seems that you may want to install a relay and/or draw power from the battery to protect your newly installed diodes.
These folks might have something useful to you, but I'll keep an eye out to see what you do!
