After 5 years, I am actually getting the heat enabled in my '78 Super.
Drivers side has new hose and is complete. I actually felt heat driving home last night.
But I have some questions and issues:
Questions:
The levers in between the seats say heat/defrost and the other Temp.
I believe the one closest to the driver, heat/defrost, controls the flapper off the heat boxes. Is that correct?
What does the temp cable control?
I want to turn off heat under the rear seat blowing forward. Will the controls do that or do I eliminate that feed and run a tube directly to the heater channels?
Passenger side blower tube to connect to the heater boxes.
Right now, there is a piece of the engine tin blocking any access to the connection to the heater box:
The space on the J Tube is blocked by that tin. I do not see any way to route it and have heat on the passenger side.
Any thoughts would be much appreciated.

Remove and rotate the deflector 180* and re install it. Need to get the stove pipe installed and hose run to the air filter. May need to get extender for heater box.

Ok, after looking at images,that deflector is not on backwards. It's actually correct, it has a cut out for the dipstick tube and fits correctly. The heater hose does not go thru there.
I was looking at the routing of the fan to heater box hose and see how it wraps around now. It goes behind the J Tube and up thru the shroud.
The drivers side is a direct shot. Passenger winds around a little.
Easy Peasy.
I will get the heat and fresh air intake hoses installed. I am not interested in the rear heat, so I will probably remove the assembly under the rear seat and run a direct hose so I have all available heat up front.
Thanks Guys! _________________ 1978 Super Beetle convertible

There's something funny going on with that deflector, it should be tight up against the cylinder and head fins, it's job is to direct cooling air to wrap around the cylinders. _________________ Rust NEVER sleeps and stock never goes out of style.

Turning it 180* is not an option. That would put it into the block, not possible.
My choice is remove it or leave it as is. There's a chance it doesn't belong to this car. The the engine was out when I bought it and could have mixed parts. It's not in the way so I'll leave it for now. _________________ 1978 Super Beetle convertible

If you want to get rid of the heat to the rear of the car, you don’t need to remove the Y pipes and replace with a straight hose. Just unhook any heater-control wires that attached to them, and close the inner flaps by hand.
This works, assuming you have still-intact on/off flaps in the Y pipes under the rear seat.

Thanks Tim. I just went and studied the assembly under the rear seat and finally found the cable that controls that unit.
I see now I am good to go once I hook up the other hoses.
Appreciate everyone's input.

This is incorrect. The one labeled TEMP controls the flaps on the heater boxes. More open = more hot air allowed into the car = more TEMP
I don't remember for your hear if it's one Y-shaped cable that splits off to each flap or if it's two separate cables (one for each flap) that connect to the TEMP lever.
The HEAT/DEF lever simply controls which vents the hot air comes out of. That lever should be connected to cables that run to the front footwell vents and the rear footwell vents. When you move the lever to DEF, the cables should close the front and rear footwell vents so that all the heat is forced up to the DEF ducts in the dash. When it's in HEAT position all the footwell vents will be open, and naturally you can run it in any position between the two extremes as well to adjust so that you have air flow where you need it.
The cables that operate the footwell vents are often missing/broken and the flaps in the front footwell vents especially are sometimes seized up so you may have a little rehabbing to do to get it to work right. _________________ 1965 Volkswagen 1500 Variant S

I think you have a LH one on the RH side, like in this pic below:
This is an earlier example shown below, there's a breather you don't have, but the tin itself should hug the cylinder and head in the same way:

I see what you are saying Busdaddy. If I can remove it and put it on the correct side, I will. As long as I don't have to drop the engine to access it, haha

You shouldn't have to remove the engine, but it may be a 2 person job to hold the part up in place from below while you screw from above. _________________ Rust NEVER sleeps and stock never goes out of style.

Thanks Almost, perfect explanation. I am getting the system fully functional so I can enjoy the car later in the season.
Next year's goal is a top!

Mental note: Right lever up, left lever down. That will accomplish what I want.
This car is so much fun now, I want to enjoy it this fall.
I am going to start buying parts for the top over the winter so I have everything I need.
I really appreciate everyone's input.

Once you get it sorted properly, you'll love the heat! The heat in the fuel injected bugs is strong IF everything is in place and working correct. You should have an S shaped metal pipe to go between the tin and passenger heater box |

How does the stovepipe mount to the engine? |
