Help with wiring 5 Baja Design LP6 Lights

Hi everyone and happy holidays

I could use some help because right now I am over thinking how to get this done.

I just bought a Sherpa Crestone roof rack (arrives Saturday) and I am planning on mounting 5 Baja Design LP6 lights where the led bar would go on the sherpa.

Here is my question
There are 5 lights x 2 (positive - negative) wires for a total of 10 wires to power them. I bought the KC Lights Universal Wire Hider (their name not mine) to run the wires down both sides of the windshield and into the engine bay. I am now worried that running 6 wires down one side of the windshield and 4 wires down the other side wont work. My concern is that 6 wires wont fit down the KC Lights Universal Wire Hider. Can i ground the negatives to the sherpa so that I would only need to run the 3 positive wires down the windshield on one side and 2 positive wires down the other side?

Now summarizing what I am asking
Can you ground a wire to the sherpa?
Is there a better way to do this?

Many thanks for the help

 

You could always ground to one of the roof rack mounting points.

 

That’s what I was thinking. I’ll run three wires over to the passenger side mount and 2 wires to the drivers side. Thank you so much

 

You’re going to control each light manually?

I would add up total amp draw and the distance to your power source to determine proper gauge wire and create a harness. Isn’t there a hi and low setting on the LP6s plus additional wire for the Amber backlight? Sorry I don’t own LP6s
