Predator Chromium Wiring Problem

I have a problem with my predator chromium wiring harness. The problem is that the positive terminal looks pretty bad, it's eroded and the pre-taped area looks burnt.. I changed the fuse, and the angel eyes are working fine. But would this cause future problem? I'm planning on repairing it if it's a simple dyi. For those who are technically inclined, can you please advise me on this issue and how to repair it? Do I just need to go to a hardware store and buy a terminal, cut the old terminal off, and tape the new one on?

You don't want to tape on the new one but you clamp it to the wire. Make sure you wrap it in some electrical tape to protect the connection.

Are you sure your positive wire is not being pinched by the weather stripping and causing a short?

how do i check if its causing a short?

Look at the physical wire itself and check for damage caused by chaffing.
