New Main Relay Ass'y Question Need Help ASAP

So I was having the hot interior no start issue so I deduced it to be the main relay. I just picked up a new one from the local Acura dealership but there is a conflict between the old and new parts. The old one is P/N: RZ 0067, and the new one is P/N RZ 0063. Also there are different brackets to mount them. If this is just an updated P/N great but I don’t want to risk it. If someone could shed some light on this it would be greatly appreciated.

Pic for reference:

When I got mind from the dealer, mine looked just like yours. The bracket on the new one is not needed. Just use the old bracket. And the part number changed to rz-0063 says the dealer. Its been working since 2010

i also had this same issue; i bought the new one and compared it to the old one and I was thinking the same thoughts as you lol. Anyways, it works 100%, all i did was change the cover from the old one to the new relay since the bracket was different on the new one. Be careful and not break it lol! Good Luck!

Ya according to my Honda fanatic buddy the RZ 0063 is the updated version so that the hot start issue doesn`t occur anymore. Thanks for the quick responses.
