Good morning everyone, I am planning to build a harness or two and need to identify this plug.



closeup view


It is the main plug that transitions the main harness on the fender-well to become the engine harness including the "coil feed, water temp, and oil pressure" on my 85 Bronco 351 HO. I believe it can be found somewhere here in a duraspark writeup but I can't seem to find it.

This female 4 wire basically mates to the main cab feed and needs to be used when any duraspark wiring is built. I can find all the other except this one.. FYI it even isn't included in the universal painless duraspark harness. Another view..



ignition harness plug


I appreciate all well-meaning suggestions about junk-yard searches etc, but I'm looking for a source of new ones..thanks all for any assistance.

 

You can just reuse that one.

Leave the water temp and oil press wires as is.

Splice into the coil positive feed near the coil.

The 4th wire will be an extra power wire (KEY ON power) you can use to power something like powering a relay.

I can't say that they have that connector, but Clips And Fasteners have a range of shells as well as the terminals that go in them. Might poke around in their web site or call them.

 

Thanks Jim..Actually this one is just fine where it's at..I'm building a couple of new harnesses actually. Anyone building a new Duraspark harness form scratch could use this one as well since it isn't included with full harnesses that can be bought for a full "plug'n play" replacement harness.

Thanks for the input.

 

Thanks Gary, I have looked on their site but can't seem to find this one, I will call them..good input.

Update..good luck getting them on the phone.

 

The entire Motorcraft Plug and pigtail catalog is available in PDF.

NAPA/Echlin has most of them too.

You need to show the plug or socket, end on from the inside in order to tell the pin out and any 'keys'.

Clips & Fasteners sells this four pin plug:

It is the same as Pico 5746c

Well done, Jim! I'd rep you but even with my recent promiscuity I can't.

 

I got him for ya

 

Thanks for the replies everyone. I'll digest those pdf's tonight for a look.

This particular male female plug arrangement is of course the main part of what will be the "duraspark coil feed/water/oil connection" for most of us in this forum.

Since all of the other plugs can be found that pertain to a "DSII" conversion, I have found I wanted to identify the "coil-feed side" connector in this case. Even a "painless" harness doesn't include this "end" for obvious reasons for those who are converting an older points system, but those of us in this forum will always confronting this plug to wire in our coils (and make them easier to service) etc...hence the search.

One of the things that always comes up in a DSII conversion is "the resistor". Since ours is "built in" it would be good info to also share where it is..and how to specifically, and easily wire up an 80-86 Ford truck.

This particular plug set uses a special "key" that the other 4 pin of the module as I'm sure you all know. At this point it still seems best to always ""never let this plug get crushed"..even if you don't need it this time...they probably aren't available anymore...(an assumption at this time) The complete solution may be to use a terminal block to emulate this connection so as to make it possible to accomplish what this plug does..we'll see.

Anyway, I have learned a lot here regarding these "bullnose" Fords, and will continue to search for the little things..thanks for the info guys..

 

Thanks. And I can't rep you.

 

It's the distributor plug that has the odd key.
Painless seems to be the only ones who have it.
(not even Motorcraft list it)

BTW, Chris has kindly put the DSII wiring thread (with part numbers) up in the stickies at the top of this sub-forum.

 

The thick red (pink?) resistor wire in my truck is coiled just above the ignition switch.
It should be around 1 1/2 Ohms for a DuraSpark coil.

You can use a Mopar ceramic ballast resistor mounted in the engine bay if your truck is some odd vintage that didn't have it in the cab harness.

ETA, I found this in a post by our resident parts guru Bill

 

Just to clarify, this plug shown isn't the one I'm looking for. This one is used for the the ICM connection...

I will include another view of the one I'm looking for. It would actually be considered the socket side of the connection I'm talking about.



Note the circled "socket"....THIS is what I'm after to create new harnesses.

This view may clarify this ..thanks for input. I'm not uninformed about how to wire it up, or how it works..just wanting to find a source for this "Socket"..for some new harnesses. Thanks for all of the input..

 

Okay, sorry.
I thought you had asked for the plug.

I still can't see how the pins are arranged or where the keys are.

Given that my '87 (w/ DSII) seems to be a bit of an oddball, so I'm not sure I can look at my own truck for what would fit yours.

I don't know of anyone in the aftermarket who sell the socket side of that connection.

If you're willing to go to a "terminal block" you might consider a four pin Weatherpak connector.
They are easy to wire and available almost anywhere.
