Injector harness

[PSID6]

I found a bad wire right above the connection that clips into the fuel injector. I just want to shorten the wires about a half-inch and reconnect everything. Is there a GM specific tool that I need to repair this problem

Would this work. I've never look at the injector plug that closely....
