    If you go from a 4 pin resistor to a 3 pin which wire do you not use?

    my guess is you need to remove the inner fender.

    Its just less of a hassle to remove the inner fender.Otherwise you make more work for yourself

    It can be done without removing the inner fender however you will be cursing your decision after fighting it. The inner fender is really easy to remove, just a few bolts and you get a lot more unobstructed room to work with which you will want to get the old suitcase out. There are a couple of studs and bolts for the suitcase that are not easy to get to. You may already know this but the outer fender does not need to be removed.

    I had this done by a really good mechanic who closed shop in California and left years ago. He did a bunch of parts swaps before some of the new block off stuff was made. He installed a heater control valve that I have to hook up to the carb vacuum manually if I want heat. I would prefer a cable operated so where do I hook that cable to?
    I appreciate the suggestions.

    You would need to run the cable through the firewall if you want to operate it from the inside the car.
    (It would make a nice emergency cutoff in case the heater core ever springs a leak.)

    I've been contemplating adding a valve to mine during my A/C restoration project but haven't found a good place to go through the firewall or mount the cable control inside.
    A manual choke cable would work to operate the valve and the valve could be hidden behind the inner fender.

    I've been considering using a vacuum controlled valve too.
    I assume they are normally closed and open only when vacuum is present... Correct?

    Instead of manually connecting your vacuum line to the carb for heat...
    You could leave it connected all the time and add a small valve in the vacuum line.
    Pop the hood and turn the valve.

    That would be easier than messing with the connection to the carb.

    Something like a lawn mower fuel shut-off valve would probably work in the vacuum line.

    That is a good idea. I was hoping there would be a way to piggyback of the cold to hot control cable to the engine bay. The heater core failed and now I want to replace it so hopefully it is not too bad of a project.

    Nothing is impossible but the travel distance would need to be the same so one control didn’t interfere with the other.

    Might be kind of tricky routing and connecting the valve through the firewall to the hot/cold door too.

    Heater core replacement is NOT a fun job.

    Google “Nasyz28 heater core” for instructions.

    Good Luck
