Where did you run your power cable through the fire wall at?

Through where the ECM wiring goes. But I also removed my ECM so there was just a hole where the wires used to be that I was able to use. You may have to drill a hole in the same area of the ECM wire harness, just be sure both sides are clear so you don't ruin anything. After running the wire be sure to seal it off with some silicone or a similar product.

Yeah I had the carpet pulled back right there the other day but cant see the other side of the fire wall to make sure I'm not gonna hit anything. I Jacked up the car and removed all the bolts from the wheel well but still couldnt really get to it cuz theres a bunch of stuff mounted to the it under the hood so I couldnt pull it out far enough. I'll figure something out. Thanks.

Yah it's a bitch getting around the heater box but can be done.
