Fighting the CPS issue on my 2006 now. Generic replacement was a no-go, which seems common knowledge on this forum, so I've got a bosch on the way.
I suspect that the wire underneath the boot at the CPS could also be damaged, the boot itself is cracked where molded to the wire.
Amazon has some plugs that look to fit but I suspect the leads are too short and would have to be spliced.
I couldn't find the part numbers on this site but you can replace the cps wire leads and connector directly to the ECU pins using the following:
