I am in need of a full wire harness for my '06 5.7 300C.
The part number is 4801437AB.
The delear advised the part is no longer available. Is there a replacement for that part? Anyone know where I can buy a new or used one?

Thanks

Welcome to both of you. What is the problem with the existing harnesses that can't be repaired?

I need the part number off of it. Part# is located under the fuse box on a white tag. You can see it without raising the fuse box. There are like 40 different ones for an 06. I'm doing an '06 Charger SRT8. Chargers and 300's are different because of the way the headlights are configured among other things.
Do you need the engine harness or the engine bay harness. The bay harness is called a Dash to Headlight harness. Some are available new but your looking at $1200ish plus shipping and taxes.
The engine harness is smaller and a little easier to come by but your still looking at $800+.
I'm going to repair my own. It was damaged pretty good in a wreck. So damage is all over, not just in one location. I could repair yours too but it might take awhile depending on how bad it is. I'd replace the necessary wires completely. I've got spare harnesses to work with.
On the mouse problem, I'd get a cat or cats if it's that bad. Moth balls are supposed to help. Can't verify that. I can't stand the smell personally. Mice and rats like cozy dark places. Engine bays are perfect. If you open the hood, it exposes it to open air and sunlight and in security. Things mice and rats don't like. Probably the cheapest thing to do. Other than set mouse traps with crunchy peanut butter on them.

My 2005 300c also need a replacement or a repair my main harness. Two ground wires from the main harness connecting to the heads on each side of the engine fried. My guess is that the big thick (6 gauge?) ground wire that attaches to the block on the passenger side has a corroded connection point. I believe that this corrosion caused an increase in resistance therefore causing the smaller(16 gauge) ground wires to draw more current. The effect of these fried ground wires caused erratic CAN bus behavior. Mr. Toad's Wild Ride ensue. When going for a drive(my last one) just touching my throttle caused the throttle sensor to direct the car to full speed ahead. That is when I learned that their was/is no such thing as a throttle cable anymore. The brakes were also affected by the bad CAN bus behavior. A deadly situation. Flatout dangerous. I was still accelatoring with my foot off the gas and buried on the brake pedal. Lucky there was no traffic. Just reached over and turned the key off at 50-60 mph. My sunroof opened on it's own one day and filled the car with 3 day worth of rain. The alarm would randomly go off. The car has been sitting for a few years now. Was told that the harness was $1500 from Chrysler and who knows how much to install. I could fix those 2 wires and hope for the best or buy another harness and install it. For the most part everything else seems ok. Has anyone else pulled a harness? Damage to the CPU? Elsewhere? I'd hate to fix this harness and have it happen again. Anyone know of any recalls? Bought it new. Still looks good and now low mileage for a 2005.
