Heater installation 2020 Mojo
Since the end of summer is near us and my wife gets cold easily it’s time to install the heater.
I just ordered the kit https://www.bakesonline.com/heater-c...eater-kit.html
Now the challenge is going to be installation.
Im planning on mimicking the manufacturer set up including yawing hash switches.
Does anyone here have a cooling system diagram for the raptor engine? Or if you have a heater would you mind taking pictures to show where the supply and return is?
Also which switch on the dash is dedicated to the heater?

I have a 2020 with the factory heater. I will take some pics and send them off to you.

When you open the engine hatch the heater lines will be on the back right if you're standing in the boat. There will be a little loop of heater hose, you'll remove that and then run your supply and return.

You will also need a circulation pump for the raptor motor:

The raptor motors don't have enough coolant flow through that circuit at low rpm without the pump, all of the factory installs have a circ pump.
Without it your heater will only be useful at higher rpm2020 Supra SA

Hi Emilware,
My engine has blue labels with “To Heater “ & “From Heater” at the hose connections. Hard to see in the pic as I couldn’t find an angle that both were visible. The blower and hot tubes have a plastic cover that does a nice job separating them from the under seat storage. Tried to get pics of the hose routing under the hot tubes but they aren’t great. Pic of the wiring shows the yellow wire on my motor is not used. Hope this helps.

I just got a quote from Bakes.com. For the pump, 2 fittings and 1 harness…$405. That’s on top of $550 for the kit.
If it wasn’t for my wife I would choose cold. Lol
