Default Neutral Safety Switch Help..Pics?

Have a 77 auto, TH350, and there is no mechanical connection between the shifter and the switch..no pin, bracket, nothing..switch is there, but does not move

Can't find a pic in the AIM or parts catalogs...

Any help (pictures!!!) appreciated

Do you have voltage going to one of the purple wires?

They are hooked to a 5 amp. fuse.

That would be a good place to start.

The car starts ok...the switch is ALWAYS in park..

I now see whats missing..the pin from the shifter to the switch.

What part is that...or can a another pin be fitted?

Go to this link here...It is very helpful. You don't fix the missing pin...you place the WHOLE switch.

Hi, don't have a actual pic but found a aim page (PIN A) and detail actuating tang.
I think it's a regular slotted spring pin, vendors don't seem to carry them but you should be able to find it in hardware stores?

Default Very very important!~!!!

Compare the OEM wires and their placement to the aftermarket plug and make sure they are the same.

The wires on the NEW neutral safety switch, on the backup lights plug (pink & green wires), are BACKWARDS from the OEM switch. They're manufactured from M&H Electric Fabricators and I think they have a bad batch. I know because I purchased 2 from ZIP and 1 from Ecklers and they all do the same thing...my backup lights stayed on the whole time the engine was running . WRONG!!!!!! When I compared it to the OEM switch to the aftermarket switch, that's when I saw they were BACKWARDS!!!! I swapped the wires, the switch works like the OEM!!! And it still works!

I called M&H Electric Fabricators on this and told them what I encountered....
