2002 Chrysler Voyager - Computer module failed, garage found the electrical wires had been too close to the exhaust manifold and fused together, creating a short which made the computer module fail. Any other history of this?

Garage is replacing the computer module and rewired the bad wires - cost $1400
Hello and welcome to just answer. I have been a Chrysler technician for 25 plus years, and have never seen this on this model. I have seen wiring harnesses become damaged from leaking battery acid, but not melted due to the heat from an exhaust manifold. So to be honest with you this is not a common problem.
The explanation above is what the garage told me. Is the wiring harness actually near the exhaust manifold so that it COULD melt? First they were saying the previous owner was responsible, then they switched to "bad design by Chrysler". The problem started suddenly (no prior warning) - driving through a tunnel and the vehicle died, started up again after waiting a couple of minutes. Then ran ok - drove it about 5-6 miles to the 1st garage. They told me "bad gas" and put in dry gas and said to fill it up with hi test and then do the same for the next 3 fillups. Put the tester on it and no error codes. Ran fine for about another 5-6 miles (hadn't filled up yet). Stopped for dinner, started the car again and white smoke started coming out of the exhaust and it was running very rough. Filled up with Hi test, and it ran extremely rough trying to get my mom home about 25 miles away (north on I-95). Went through about 1/4 tank going those 25 miles. Parked over night and same thing the next morning. Had AAA tow it to another garage. They are the ones who diagnosed the computer module failure and then when installing the new one found the wires fused together.
Ok after reading this, I am thinking that maybe the fuel injector harness melted, and can get too hot near the left rear area of the exhaust manifold. The injector harness shorting/melted together would cause some of the fuel injectors to spray constantly which explains the white smoke, rough run, and horrible fuel mileage. Now I am thinking that your computer may still be ok, and the harness was the only problem.
