Speed control what are the bulkhead pin numbers?

[Wonderwagon]

I have a harness off of a 69 Chyrsler, marking the connectors as their intended purpose. First is a ring terminal to a single contact insulated black housing. The other two are black/ black red terminating in pins 25 and 29 of the white bulkhead connector with the double keys. Sun backed color shifted. Any thoughts?

I would expect that info would be in the factory service manual. You should be able to download one free from
Service Manuals – MyMopar

Yes I've looked, my FSM is for 691/2 Plymouth. Most harness to bulkhead connector pinouts matched, When continuity was checked. Pins 25 and 29 are not used according to the FSM. The Plymouth FSM is how I determined the pin numbers; these are not used, hence the question, and the contact insulators are factory in appearance.

Not sure of the ring terminal, but 25 and 29 look not to be used for anything. The same plugs are used across the models, so running across unused terminals isn't surprising.

Agree.

As much as I like to point people there, the 69 Chrysler manual is not available.

In looking at the 69 Plymouth manual.
The diagram on page 8-119 clearly shows it going to pins 1 & 2, this is consistent with the diagram on 8-124.

Thanks for the update Alan - I know there are some gaps in what they have at mymopar, too bad. It's an excellent resource regardless, so I tend to send people there fairly often.

I don't know why you are looking at pin/connectors 25 & 29 but in the engine bay wiring diagram for the 1969 Plymouth Fury FSM you only need to be concerned about the 6/2 5/1 connector from speed control to bulkhead. All the wiring from interior bulkhead on the dash wiring harness should be there already with plugs for the dash stalk & brake light switch. Plymouth & Dodge are pretty much carbon copy, Chrysler? Who knows YMMV, examine the color codes of the wires.

Here's a engine bay wiring FSM diagram without all the unrelated speed control items that may confuse some.

The 1968 Speed control was much easier to pull & and install IIRC.
Even my 1976/77 Gran Furys were a easy pull/swap.

When I went to the boneyard what I'd do would be is grab all the engine bay stuff, just unhook the wiring, grab the added throttle pull clip and springs in that area of disassembly, speedometer cables, down by the transmission maybe a bugger if car is not high off the ground (bottle jack in your tool bag), grab the speedometer gear while your there, toughest part is the stalk as you have to pull the steering wheel (have your puller handy) and also (I think) you have to pop the pins out of the lower connector to get the wiring harness to be pulled out of the column. Grab the brake light switch. And from 1969+ you may need the wiring harness to the transmission switch. But all in all it's a fairly easy swap out and is a much needed beneficial option. I think I only paid $20 for a single pull, if I was getting some other items depending on the yard it would be a added $10 item.

Picture is worth a thousand words . First is the bulkhead connector, Position 25 and 29 have pins installed, thusly used. Second is the sub-harness attached to those pins. Yes the 69 Plymouth FSM shows these open. This is from a Chyrsler which ha a 440

Re-Reading your original post, what exactly are you doing here? Something with adding a speed control, into what? Your profile pic shows and nic leads me to believe you have a 1969 Plymouth Fury Station wagon. Then you say you have a Chrysler wiring harness, are you trying to use the Chrysler harness to install the speed control in the 1969 Fury?

I see a jumble of wires that look like from the engine compartment lower bulkhead connector and more mention of PIN 25 & 29 which have nothing to do with the Speed Control. Pin 29 is HEADLIGHT DOOR (I believe)

Here from the 1970 Chrysler FSM PIN 25 is for a 60 AMPERE ALTERNATOR

From the same 1970 Chrysler service manual just the speed control wiring, I really doubt 1969 is different.

Simply IDing the wire harness pin out uses. Bought the harness for the positive battery cable, to use as a pattern for my Fury Wagon project. According to the fender plate it's a 69' Chyrsler. Thanks for the info
