Fuel injector and OBDII harnesses
 

My 95 F-150 4.9 5 spd was saved from a field, but not before a field rat had snacked on a couple of harnesses, mainly the OBD and fuel injector harnesses. Has anyone ever rewired these instead of getting a new harness, and if so, can you offer any tips? The OBD was chewed in a spot leaving wire on both ends, so it shouldn't be too much trouble. The fuel injector harness is a little more involved. Any tips, hints or diagrams would be greatly appreciated. I'll try to get pics posted tomorrow.
Thanks
