wiring harness help

so i have four pro comp lights and an nfab light bar but i dont want to spend 40 dollars on a wiring harness that comes with two switches that dont even fit into my dashboard. i was thinking about buying two switches from toyota and than buying a seperate wiring harness.

is that they way to go? or is there other more efficient ways

 

The lights didn't come with the harness? My hella's came with a harness, relay, switch, and fuses. Installation was easy and it was my first time doing it. If your lights came with the harness, you can always ditch the switch and get this one that should fit into a stock slot. http://www.oznium.com/gsw-45

 

the procomp's should come with a harness unless you bought them used. you can do that if you have space, leep it nice and clean.
