so im pretty sure i have a short in my injector/coil harness and was wondering how hard is it to remove i know it has more connections in the harness than just these two but is there a place to unhook this harness from and remove it? ive looked and it looks lke it plugs in behind the engine somewhere.

It's part of the wiring harness. Either find the short/open/high resistance, or replace the whole wiring harness. It's a real bitch to get at the back connectors with the intake on though. Might be worth your while to actually find the problem.

Use a multimeter and check for continuity and high resistance between the injector connector, and the ECM connection.

The wires that go to the back of the engine are the O2 sensor wires. Unplug those(2)
and the big connector that is up against the firewall on the passenger side(unscrew the bolt that is in the middle of this connector to get it off). After that, unplug all injectors/spark plugs. I think there are also like 4 sensor wires that go to the front/sides of the motor that will need to be unplugged and you should be able to pull the whole harness off then.
