Yes, the new fans are three pin.
I just cut the computer motherboard connectors off, and wired the motor power wires to the old connectors I cut off of the factory Dometic 92mm fans.
The wires on the new fans are all black, and it wasn't clear which one was the rpm sensor I didn't need. On my bench I used a pair of 18650 3.7v Lithium Ion batteries in series, and connected them up until I found which was positive and negative for the fan motor. The fan's will run on anything DC from 6.5-13.8v, so use what you have including the 12V battery under your cars hood.
When you've identified the correct wires, just connect them to the connectors from the original fans and plug them into the factory Dometic wiring. Make sure you connect them so the fans blow in the direction of the arrow on the fan, and mount them so they blow up.
The original baffle on mine was in two pieces, remove the screws in the pic and the top section comes right out. There are three more screws holding in the lower section of the original baffle, two are near the top on each side and the other is just above the top of the bottom fridge access panel opening.
After removing the top section, I drew a line along the bottom of the top Fridge access panel opening, then removed the three screws holding the bottom section in place.
That made it easier to cut the bottom section to be even with the bottom edge of the lower fridge access opening. Now if I cut the zip ties and slip out my new upper baffle I have easy access to the fans.
I left the bottom section of the original baffle as it may help to keep the air closer to the fridge plumbing removing more heat on the way up.
