-EDIT- By engine harness I mean the wiring harness that goes from the passenger side and includes the fuel injector connectors and the solenoid connectors.

I keep on having to take off my manifolds to move the harness around.
Either I can't get all my crank angle sensor plugged in or the plugs towards the firewall won't reach.
I had it pretty close earlier, but was going to have to extend a few of the wires to get it all to work.
I have to take apart everything to get to a firewall heater hose because as I was filling the antifreeze I noticed it all was pouring out.....
