use something small and sharp to poke a hole in the harness, then use just a tiny bit(I mean barely any) of grease on the pcm pin and slide it in. Mine went on without a fuss.

you will also want to pull the PCM off of the connectors and then slide the pastic (blue or red) covers off. the tabs dont like to slide out enough with those covers on to let the pin in fully without really forcing that shit in.

So do I need to get a female connector to crimp on the wire and then slide it in the plugged hole??

Pin 42 on my PCM connector just has a little rubber plug in it. Is this what you are talking about poking a small hole in???

Thanks for the help:head:
