I am the go to fix it guy for the family DA63T with a K6A injected engine. When it had no power under load, I checked the air intake system and found a rat nest in the box. Both boxes were removed, cleaned and replaced with a hardware cloth rodent blocker inside frame hose. I cleaned away the nest that was around the engine, and noticed one injector wire chewed in half, insulation and wire missing so naturally no start. My question is can a single cap with wires be obtained and soldered into harness? Is there such a thing as a harness just for the injectors or is that harness a part of the ENTIRE harness? Does anyone know the brand of the injectors so I can search for a cap? We have a pdf of the maintenance manual but I found no details on these. I also wonder if there is a special tool to remove the plastic cap or a simple work around for any special tool. Thanks in advance for any help.
