    I have a reverse switch on the shifter which looks original. I don't think four speeds have neutral safety switch's' do they? I will get a picture of it tomorrow

    Interesting. Yes a picture is needed. The reverse lights should be on the case activated by the linkage rod and there is no neutral switch.

    Are you sure that is a toploader? I have two and either of them look like that.

    Are there any part numbers you can see on the case or the tail shaft? I think you have a 70's 3+1 OD unit.....

    I'm 100% certain that is the reverse light switch. If you want to double check me, put a multimeter with one lead on each of those two terminals and shift the trans into reverse. If the circuit completes when in reverse its the reverse light switch.

    Its a 73 toploader RUG HEH.

    I tested it with a multimeter today to see if it would close while in reverse and it didn't but oddly enough it closed when shifting into 3rd

    I think the switch is something for emissions. I downloaded a wiring schematic for a 72 and it shows a switch for manual transmissions. One wire from the electronic spark control and the other goes to an emission vacuum solenoid. I don't have that stuff on my car, it must have been removed from a prior owner. The schematic says the switch is open in third and forth but when I tested it closed in third. I found a parts diagram at the same web site which had a lot of usefull info. the switch is number7E449. http://www.7173parts.com/images/tech/illustrations/9881.jpg

    The Ford book lists a such a switch for 73 Torino and Mustang with 4-speed manual transmission.

    D2OZ-7E449-A Switch, Seat Belt Warning Sensor (D2AR-7E449-BA)

    I'm guessing unless you are hard-core trailered show you won't bother fixing this one.

    I guess by when you get to third gear the seat belt warning goes on, I won't be trying to hook this up. I guess people get rid of stuff like this along with those key buzzer relays.

    IIRC, it was supposed to buzz and illuminate in any gear. The 73 also had a sensor strip in the seat bottom, and switch in the belt buckle, to make sure both front seats had their belts on, even a bag of groceries. Remember, this was the heyday of the safety fascists. Some cars disabled the starter unless everybody had a seat belt on.
