I'm in the process of putting my 1964 Biscayne back together and noticed this blower motor electrical part just inside the passenger side front fender. Is this the point where my power source (hot) connects to? I did not have a wire in the new harness that ran to this point.
yeah, but you probably want to connect this motor terminal to the switch, and connect the hot wire to the switch, then you'll be able to turn it off, and maybe adjust the blower speed.
Yes, there is usually a resistor, and a small wire harness that connects the resistor to the switch. Which might be where that motor wire is supposed to be, but someone removed that little harness, thinking they didn't need it.
I see the 3 prongs and the connector that was hanging there. I will connect them tomorrow. Where is the wire under the hood that connects to the single prong?
There should be an orange (? brown?) wire from the little harness that connects to that resistor thing, and to the switch, which you connect to the blower motor.
On your bulkhead connector, there should be two connectors of 8 spaces. Originally the connector with only 7 used spaces will have your heater blower connector, if you are not sure which connector that should be, it is the same connector that the coil/ignition power wire is connected to. If your new harness follows factory wiring layout. Again going by factory harness, it should be SPACE, Ignition(color changes based on engine), Dark Blue, Purple. Black-Yellow, Dark Green, Black-Light Green, Black-Orange(blower motor) Black- Orange wire is the power wire to the heater motor. Should be a round connector to fit, sometimes it gets mistaken for a radio doo-dad due to the weird shape. I'll see if I can dig up a diagram... Yeop. IIRC LOW- Black-Orange(not the same wire as power feed to the motor) Med- Black- Light Blue High- Black- Yellow. If original colors are used.
