Help with short in wiring

I have an Evo IX with about 2K miles. I have a short going from the ground wire to the exhaust cam position sensor tracing up through the wiring harness. The only visable damage is the chassis ground wire going from the firewall to the intake manifold was broken during clutch install which was done a month ago, but I didn't start driving the car hard until Sunday during the AMS tune when my car ran great. Then the next day while driving my car gave a SES light and died with a cam sensor error. Any help would be greatly appreciated as the dealer wants to charge me $1700 plus $600 labor for the wiring harness and $300 for the transmission harness. The Mitsu tech thinks damage to the wiring done during clutch install when the engine was moved was the culprit, but the shop that did the clutch install doesn't believe they could have done the damage. Anybody got any ideas?

Thanks for time and help in this matter.

Who did the clutch install? If it was done by an outside shop, I would take it back to them.

I would definitely repair that damaged ground wire first and then go from there. Good luck.

You can find a good auto electric shop and they will fix the harness for you for alot less than a dealer will charge you to replace. Although replacement is the best, most reliable fix. Wiring harnesses are not difficult to replace yourself, even you are even only slightly mechanically inclined, you can do it.

Do you have the stock battery or a small battery kit?

I have the small battery kit. It's actually called a Deka and is only 11.5 lbs. It's the same one as the Braille. Do you think that could cause the problem?
