yeah I installed one of those the other day.   Its a nicer layout,  and pre-wire is much easier.    Hopefully they dont have the same issue with "lock up mode" as the 425 did.  

As long as we're on the subject; I've done quite a few installs of the CA645/545 series and I have one question I haven't been able to get answered.  There's a small box (almost looks like a miniature relay; but with only 2 wires) included with the 645 but there's no mention of it in the documentation.  I've consulted with several installers with years of experience with this line and they've said they don't know and just never use it.  Just wondering if anybody could provide some insight?Life moves pretty fast; if you don't stop and look around once in a while; you could miss it.

Hood Pin. If it is the same thing i am thinking of. They swiched there hood pins to the lquid hood pin. I THINK.
