81' stepside Neutral safety switch
I have a question about the neutral safety switch on my trucks transmission.
I have done searches on this site and called LMC, Ford parts and asked as many parts dealers as I can find but no one can find the part I need.
The neutral safety switch works properly to not allow the truck to start in D or R however the back up lights do not illuminate in R.
I have jumped the two wires together that go back to the reverse lights and they illuminate. the fuses are good, bulbs are new.
I ordered a new NSS for my truck however every...single...part I order has a 4 WIRE plug. Mine is only a 2 WIRE plug. a purple black wire and another dark colour could be black or brown I cant tell its dirty.
My truck is a 1981 f150 with a 302 and C6 auto. how ever I do not think this is the original engine, the block code is D10E 6015 AA, that should be 1971 302. I cannot see if the transmission is original or older.
Does anyone have any knowledge of the Neutral safety switch for the C6 Auto which only has 2 WIRES coming out of it and a plug for 2 wires.

Thanks for replying.
That wasn't the part I was referring to however. The type of neutral safety switch I have is a half moon aluminum piece that bolts to the side of the C6 right at the kick down lever.
I ended up trying the part I ordered which had the 4 prong outlet. I simply ran two wires from the purple and black pink wires of the NSS to the harness on the chassis, it works, I just taped up the two connectors and zip tied it.
So this is solved, even though I still cannot find a NSS that has a 2 wire connector the 4 wire works with some ingenuity.

I know earlier (70's back) auto-trans trucks had the reversing light switch on the steering column, but presumably still had the NSS down on the trans.........so maybe your trans has also come from an older truck.

It may have, curiously the nss on the trans directly plugs into reverse lights. No power or starter relay wires at all and no evidence of wires that were cut away previously

Could this be a 1980 and not a 1981... 1980 has the NSS mounted on the column, and the backup lamp switch mounted on the transmission.
The black/pink wires are the backup lamps; red/blue-stripe is the NSS (and ultimately to the starter relay on the fender).
This is the only thing I can think of that would explain having only the two black/pink wires down there by the transmission.
The D10E casting number doesn't tell us much, that is just a casting ID of the block and doesn't mean anything in particular.
Post a picture of the Certification Label on the driver's side door jamb (upload your pictures to a hosting site a la photobucket and then use the IMG code they provide to make your pictures show up inline in your posts).

Could be an 80 truck. I'll check the door jamp in the morning, truck had the body and paint redone years ago I'm told I hope its there.
Its a Canadian truck as well and I've know there to be very slight discrepancies between a model year and options / tech on some older Chevy's so who knows.
