My 13BT had a metal hose fitting in the block that a rear heater hose connected to.
 
Thank you. I really appreciate that and @bj70bc as well.

I believe I have it sorted teeing into the front heater core lines right at the firewall with a pair of these fittings.

Looks like there is another T on the driver side

Thank you. I didn't see that superseded from brass to plastic. Those are much more readily available.

Now I'm scared to open this can of worms. Which heater hose connectors are better - brass, stainless, or plastic?
If you can't obtain the proper OEM T fitting and have to fabricate then use a metal fitting. A quality metal fitting is better than unknown spec generic plastic T. OEM would be best no matter what it's made of.
 
Anchored down and waiting for the next free time to do bracing. It was a tad tricky backing in the Tundra, but doable if a storm is coming through.

This is great. Thank you for taking this photo.

The RH side is going to be easy. T-fitting + a rubber line going to the back.

The LH side is strange. It actually does not use a T over there from the factory. It connects directly into the block, where a freeze plug normally is. I'm curious why Toyota didn't just use a T on that side as well.

Nice rig, interesting to see that you didn't choose the summit bar with the 63mm hoops.

Also curious as to why Toyota left the older style hood on it rather than the new style that we get here in Australia.... would have thought that all rigs would be updated with the new one.
 
Nice! Looks like a LHD from the first photo.

Thanks! The only bar offered for the 76 here is the deluxe (got the summit on my Tundra)

That I don’t know 🤷🏻‍♂️ whats different?

Cheers!
 
While waiting for a different RS3200 module to arrive (Toyota made a million variations of them), I put some work into installing the rear heater. In doing this, I found 1000 MUD posts on DELETING the rear heater and exactly 1 post on ADDING a rear heater. So, I guess this will bring that total up to 2 now.

My truck didn't come with rear heat, so I cut the hole in the floor. I extrapolated measurements based on photos from MUD. Got pretty dang close. Off maybe 3mm.

I found a rear heater off Yahoo Auctions super cheap, but I quickly realized it was a 12V edition. So, I found a 24V motor on PartSouq (87104-90A04) and a 24V resistor from CityRacer (989337-6620). The resistor was the right part, but it was too many ohms. The fan would not start on its own in HIGH. So I installed a 12V resistor from NAPA (ECH BR14), and all is well. Strange.

There was a spot in the steering column relay bank just waiting for the 4 prong rear heater relay (Niles relay 4CT-1M)

I moved the rear heater switch up to the front (Connector Experts CE4018 and CE4337).

Then, I installed a USB charger in the back (Blue Sea Systems 1039). I chose to tap into the rear lumbar power circuit. It's fused and has plenty of juice.

Next up is to run the lines from the rear heater core to the engine block. If someone could snap some photos of where the lines enter/exit the engine block, I would be grateful. The drawings are easy to find, but they are a bit unclear.
Oh that's a clever swap. Been driving my in-laws a bit lately and am always fumbling for that button...hmmm. I like it!
