this is tru. and not to hijack the thread. sorry for doing so and to answer the thread. Just undo the harness connectors 2 bolts and then u can get to the 4th plug wire quite easily. I didnt have to really move my harness much, but its new thank gawd, and that wire will pop right off that plug

Yes i can not get the wires thru the tight spaces they are threaded through.
