Extra mouse power

[jrd1990zr1]

Pulled the plenum look what I found by the starter. Looks like the past resident dined on the purple wire to the starter.

I have been thinking that I can use some heavy shink tube then cover with liquid electrical tape. Any better suggestions on a repair?

Since I am at this point should I just go ahead and pull the injector housings to clean them up. The more I remove the easier it seems to get into the area for clean up. Thoughts?
