Need suggestion about running wires.

Need suggestion about running wires.

I just purchased a new underglow kit for my '03 S. Its the 7 color blaze kit off of oznium.com. Really amazing product for the price. The only thing is I've encountered two issues with the install. The first issue was how to mount the tubes under the car which I quickly was able to work around since it seems like more people than me have had the same problem. Now here's the real problem though. I want to mount the ECU for the system on the interior of my car out of harms ways of the elements here in FL *mostly I want to keep it dry and no where on the exterior of my car is safe during hurricane season* The problem with that is that the wires connecting the tubes to the ECU are about 3/4 cm in diameter and there are 4 of them. When I ran the wiring for my interior lights I never saw a spot in the firewall capable of holding wires with such size. Is there any where yall know of that I can run that sort of wires to the interior? Did I overlook something on the firewall? Or do yall recommend just roughing it and finding a secure place some where in the engine for the ECU?

I think the only way you can do it is by poking a hole in the rubber grommet in the center of the firewall and passing the wires through that.

yep i agree with what he said. But if you look at your trunk, under the spare tire, there is a rubber sleeve thing which i ran my wires through and then sealed it with some rubber sealer afterwards. I dont recommend poking the firewall unless it is a last resort.

when i had my exterior neons i had drilled a hole in the firewall and installed a rubber gromet

Wow, I never thought about doing that. Thanks for the idea.

go with the rubber gromet, I had to resort to that for my color storm underbody kit.

follow your steering colum to the firewall and there should be a rubber gromet just poke a hole in there and run the wires through
