  1. How do i install a neutral safety switch to a 1967 mustang coupe, with a c-4 transmission.
    mike mendez — April 21, 2011 8:09 PM

    The neutral safety switch is located in the driver side of the transmission and is pretty easy to remove and replace. Two 7/16 bolts hold it in place and there is a wire attached that runs up to the firewall, remove bolts, disconnect the wire and slide the switch off.

    Where can I get a 1967 wind wiper switch assembly? I see in your schematic but can’t find the part. Thanks Terry

    Wow.. This is AWESOME!!!….
    Quick question. Hopefully someone see’s this…
    Can anyone tell me what the pink resistor wire that comes off the back of the ignition switch goes to?

    The pink resistor wire is 16a. Notice it is connected to the green with red stripe coming out of the back of the ignition switch. It goes to a 4 position plug located under the dash to the left of the steering column. It joins into 262 brown wire that continues to the starter solenoid that supplies 12 V for starting only.

  2. Im trying to locate the diagram for the oil pressure gauge, but don’t see it where I thought it would be posted. Does anyone see where it is?

  3. Hi dears
    i need your support , I have 1967 mustang Coupe,
    There is a group of wires I don’t know what ends with it.
    Orange Blue
    White blue
    Green Brown
    White Green
    Blue Yellow
    White Brown
    Blue black maybe
    All the wires above in one outlets
    how i can send to you attachment

  4. For 1967 Mustang: Does the automatic transmission shifter position light connect to KO +12V or to the variable intensity instrument panel lighting +12V? Black-Blue Stripe wire.

  5. I’m changing from 1967 OEM Mustang gauges to custom/somewhat similar gauge cluster and need pin out of 12 pin molex connector and need break down on how to connect ‘dual brake lights’ (I only have one terminal on the new connector for brakes..). Does brake connector only illuminate a brake failure on the gauges(maybe lights a red light?) and the brake switch on the pedal is powered straight from the fuse block to light the tail lights? Appreciate the help.
