Help wiring 2 led components

Hi, okay you guys seem like you know what to do with leds. Soo I recently installed a set of procomp S4's (http://www.procompusa.com/prodDetail...4242&plID=1849) on my bull bar of my 2nd gen tacoma.. I have them wired through the grille with the harness with the relay mounted next to the battery on the inside wall, with the power directly connected to the battery, then wired to the inside of the car onto a switch.. I recently got A 50" led radius bar made by HELLA (http://www.4wheelparts.com/Lighting-...n=HLAH71020471) and I want to mount it above the windshield. I have the mounting brackets but no harness.... I currently only have the pro comps wired to the car and they work functionally, but my two questions are, how should I wire the bar to my car (regarding the other harness for the pro comp, how should I go about wiring this in respect of having another aux already installed, but also to keep them functioning on seperaye switches).. And also, how should I go about wiring it to the car, because my idea is to mount it and bring the wiring through the weatherstripping in the door and bring it though the inside of the car through the battery? Please help.
