Hi all
I have recently converted my 1986 f150 4 speed manual 302 to an auto c6
The truck used to require the clutch to be fully depressed before starting. I now need to change this to create the same signal in Park on the automatic shifter.
Would this be as simple as attaching the two wires that used to connected to the couch safe, to a micro switch on my b&m shifter?
Believed part numbers the clutch safety is
E4tb 11a152 aa
Also on the same metal bracket is a black push switch p/n E4tb 9d809 aa
Anyone have any ideas what this is or where it connects?

ID Engineering number on the clutch safety is: E4TB-11A152-AA
Also on the same metal bracket is a black push switch ID Engineering number E4TB-9D809-AA Are you sure this is the number?
9D809 is the "EFI Engine Idle Control Switch & Wire" which is only listed for 1985/89 Ranger/Bronco II. EDIT: See post #4.
Thankyou numberdummy for quick response.
I'm positively on part numbers. Got part right in front of me. Any idea how the idle control switch works? Bit confused with it being under the dash.

I had to go out to the garage to look at my Master Cross Reference Catalog to find this ID engineering number and then the part number.
It seems 9D809 refers to one thing on Ranger/Bronco II, to something completly different on F150/350 & Bronco. (sigh)
E4TZ-9A837-A .. Speed Control Release Stop Switch-Use with factory installed Speed Control / Marked: E4TB-9D809-AA
Awesome thankyou so much for the help. The truck did have cruise control. (now removed)
Will explain why I can not find the connecting end of this plug.
Are you able to shed any light on how the clutch switch operates?
Not sure you picked up on what Bill/NumberDummy said, but if you have a part in front of you the numbers you are seeing are not the part number. They are an engineering ID number. Sometimes the catalog lists the part number as well as the engineering number, and sometimes it doesn't.
Anyway, the wiring diagram for the neutral safety switch is here: Start & Ignition - Gary's Garagemahal. And the transmission actually has the switch in it, so you just have to wire to it.
I wired the two wires from the neutral safety switch into the microswitch on my shifter all work exactly how it should. The truck will only start in Park or neutral now.
Thanks again everyone for the help.
Numberdummy and Gary; do you have any history on this engineering number system? I.e. Why ford uses it, are they still using it, and how do you guys cross reference them?
From what Bill/NumberDummy tells me, it started in 1956. I don't know if it is still being used, but certainly went up past our trucks.
Bill apparently has a cross-reference book, but I don't. The only way I have a chance of crossing them is to check the parts catalog. I search the catalog for the engineering number someone has and sometimes find it. Probably only 1/3 of the time.
The system defies logic. You get people saying "I know that's the part #, I'm looking at it", and it is hard to get them to believe that the number on the part is not the part number.
I find people all the time advertising NOS parts using that number, but unless someone has the part in front of them to get a number from, or a catalog with the numbers, it isn't likely they'll find a buyer.
I understand the difference between an engineering number and a cataloged part number.
It makes sense when you had parts spread across three different makes of vehicle, and those parts were subject to upgrades that assured fitment retroactively.
