You buy rolls of different gauge wires thats no problem. Now as far as the connectors you can get them at the dealer there expensive though. Also www. Rockauto. Com sells connectors for less I dont know it they have every connector you need.I have a 5 percent discount code I will share with you if you want. Another alternative you have depending on how many connectors are chewed down to the connectors and are not repairable and how bad the wires in general are chewed. You could get a used engine harness from pick a part or get a new one from the dealer depending on the price. Without seeing the actual damage its hard to give my opion on which route you should take. Let me know as much as you can and I will help you the best I can.
