    67 ing. wiring diagram

    for those of you who have completed the air cond. in a 67 mustang where did you hook the power wire up on the back of the ignition switch. where might I be able to get my hands on a schematic of that circuit.

    Re: 67 ing. wiring diagram

    I found the factory assembly manuals to be extremely useful for this type of stuff.  They show the proper routing of all vacuum hose, wiring, ducts, etc.  I discovered that my car was missing half a dozen small clips and hardware to route and secure everything properly, but based on the diagrams in the manuals I was able to fabricate the necessary parts.  Now things like my flashers aen't just banging around inside the dash.  All the Mustang parts houses carry the reprints.  I highly suggest buying a full set.  Over the years people took these cars apart, lost parts, or just forgot how the were supposed to go back together.  The manuals can rectify all of that.

    Re: 67 ing. wiring diagram

    If this is for the Vintage Air unit you were talking about in the other thread, the keyed hot, violet / purple wire, goes on the stud on he back of the ignition switch. It was easier for me to do by taking the switch out of the dash. Disconnect the battery as a precaution. I didn't realize it when I was connecting mine, but that  terminal in the picture is hot when th key is off or in accessory!!

    Re: 67 ing. wiring diagram

    so, the way I am reading your post, DO NOT use the post on the back because it is hot all the time? i thought you only wanted the air cond. to be opernational in the run possition.

    Simple enough to check, just hit kit with a test light or multimeter.  If you've got the bulb lit or 12 volts all the time its hot all the time.  Typically in automotive wiring solid yellow indicates hot all the time, so if you see a solid yellow wire its about 99% that its 12V directly from the battery.  Red for some reason is typically keyed 12V.

    DO use the threaded stud.

    Disconnect the battery or use extreme caution removing the switch from the dash. My switch had a male connector, see picture in other post, that was not insulated and it’s hot when the key is off.

    extreme case, I pulled the switch out of the car. I used an ohm meter and found that there are two post in the ign. switch that could be used. the one I chose was either orange or yellow and no power to it other than when it's in the run position. thanks for all of your replies, I really do appreciate it, be blessed.

    Bolted to the floor; I am at the point finally to calibrate the control panel. do you only calibrate the one which is to the blower speed, or all three? or are  they all calibrated at the same time? it appears that procedure would calibrate all three.

    Val, all the levers need to be calibrated. I did all 3 levers at the same time.

    Re: 67 ing. wiring diagram

    than you, I put one of the older systems in my falcon years ago, as I remember it, it took me a couple of days. this has taken me all week. as with anything new, I have taken my time. double checked everything as I go. I will post the results back to you, as to the out come.
    trying to get ready for the local car show this weekend here in Big Spring. the mustang I have been working on is for a friend of mine. he doesn't have the physical ability to do this kind of work any more so I stepped up. this site and the people in it remind me of the days long past, where people helped their friends work on their cars because of they were just that ...............friends. so, I put you in that category as well, thank you so much, be blessed.
