Sorry if this is already a post or something, but I never saw anything. So, I did the car audio install myself, and was reading on here to run power wire through existing oem grommet left of the clutch/brake pedal and into the driver side fender. Well, after I did all my work of runningrca, remote turn on, and power, I drove around and after about 5 miles/10 minutes I received a cylinder 4 missfire. So not talking at all about the engine, just wondering what wires run through the oem grommet, because I feel I may have stabbed through them? I did have alot trouble trying to use my wire fish and my 4 gauge wire through, had to use a knife to open up the grommet alot. btw I know the small one is the hood release. but there is a large cluster. im wondering what wires they are for? thanks in advanced.
