This is EXACTLY how I installed my extra lights. Thanks to Josh S. for his help.
I also installed these on Turbo Steve's ride. There is a specific size for the female spade connectors that Josh told me to buy, I can't remember now, but maybe he'll post here.
This is a GREAT mod. For those of us who have been rear-ended, it's nice to have the extra lights. I didn't disconnect the wiring harness, just left it connected.
