Needed Duraspark Ignition wiring diagram or info

Post #1 by CoupeBoy » Fri Jul 13, 2018 1:14 pm

I'm trying to find information on the 'right way' to wire up a yellow strain Duraspark II ignition box.
This box would have been used in 79-81 Mustangs with the carb turbo 2.3L i4 cars.
I can find the diagrams that work for blue and red, but not yellow.

I'm working on an old school method for how to retard timing underboost.

The normal blue/red boxes have a built in 5 degrees of retard when the white wire is engergized, the yellow has another 2 degrees via the additional plug.

So what am I actually trying to find?
This is the 'normal' wiring that is easy to find.
White Wire - Start Terminal
Red Wire - Run Terminal - 12v Battery Positive through Ignition Switch
Purple Wire - Input Signal Negative from Ignition Pick-up Coil
Orange Wire - Input Signal Positive from Pick-up Coil
Green Wire - Ignition Coil Negative Terminal
Black Wire - Battery Negative - Ground from Distributor
These extra wires, I'm trying to track down their intended use and voltages. (black seems obvious)
Yellow Wire - Run Retard Program Line Return
Black Wire - Run Retard Ground Terminal
Brown Wire - Run Retard Program Line
Am I overthinking this?
Do I just hook yellow to one pin on a pressure switch and the brown to the other?

In the below link you will find the wiring diagrams (in PDF) first three are for the 1979, 1980, & 1981 Ford Mustang's should also cover those years of the Mercury Capri's too. Good luck on your project :thumbup: :nod:

I left out a few details.. I had looked at those diagrams already, and they are only good for NON-turbo cars.

Here's the pic for the 1980 ignition where it only shows 2 connectors, yellow strain has 3.
1980_Mustang_Wiring.jpg


Here's the rest of what I've looked at, I left it off because I thought it was getting too long.

After picking up the GM draw through turbo setup at a swap meet, I started thinking about timing control. And I figured that somewhere along the line somebody must have figured out manual timing control. And I found that Ford did.. from 1979-1981 the 2.3L turbo cars were carburated and used a 'yellow strain' Duraspark module.

Before I found the Ford info, I had already found GM 5-pin HEI info.

This shows how to wire a pressure switch to trigger the timing retard.
http://www.instructables.com/id/Dirt-ch ... ed-engine/

More digging turned up information on the Ford system, but not quite everything.
https://www.fordmuscleforums.com/all-fo ... ction.html

Based on the Ford Muscle link, I found a Wells F110 module on Amazon and ordered it.

Finding Blue Strain wiring is easy, same as Red strain. (attached)

But yellow strain apparently somehow skipped being documented.

I've checked Autozone wiring diagrams, they conveniently skip the 79-81 turbo models
https://www.autozone.com/repairguides/S ... 5280065bf4

I found a thread on FourEyedPride that shows wiring diagrams, but not the turbo ones.

You can apply power to the white wire and watch your timing step back on any Duraspark II, Blue, Yellow or Duraspark III Brown

Yellow Strain is both Duraspark II just makes it easier to externally and additionally pull out spark advance via the Distributor Modulation Valve (DMV) or the altitude-compensating spark retard. DSIII with Brown Strain relief accesses the BMAP sensor, similar to the later TFI MAP sensor on EECIV Fords.

You can use the old white wire to do it.




All Duraspark II/III's have a built in 5 degree retard on start. The Yellow Strain Refief has an additional 3-pin wiring connector, and two Yellow strain relief bushing's. The Duraspark II control module with a Blue strain relief bushing has one 4-pin connector and one 2-pin connector.

Lazy JW wrote:If you are using a stock DuraSpark 2 ignition, verify that the ignition is receiving the signal to retard the ignition while cranking to start. IIRC it is the white wire that needs to have 12 volts during cranking; this retards the spark ≈ 5° for easier cranking.



Former user here, Mark P, described that the usefull Yellow Strain Duraspark Module, and the DSIII Brown has a BMAP interface to dial in or out advance, via what was the IGN pink wire. That normally whent to the Wht I wire, but there are various wiring diagrams on the web, and according to PSIG at fordmucle forum, ones called "conversion wiring" may have issues.

For example, one diagram uses the starter relay "I" terminal for just the white wire for start retard (that's OK), but powers the module from the coil wire after the resistor (not OK). That forces the module to run on fluctuating voltage averaging 6 to 9 volts.

Additionally, the Duraspark II replacements vary.

Old convention is is

Red-
Wht-
Grn-
Blk-
Pur-
Or

and the new is
Gr-
Blk-
Or-
Pur-
Red-
Wht

Yellow is best found used, and to track down a

(Each from the outside edge)

Newer replacements have moved away from the stock 1977-1984 Duraspark II wiring protocol, so it can be a little hard to locate a working diagram of the Duraspark II/III Yellow Strain Relief box.

Any Central EFi 5.0 (1980-1985) or Feedback Carb( VV2700/VV7200) can aditionally be Duraspark III and EECIII equiped.

The little 2.3 has a feedback Holley Weber 6500 for CA or Hi Altitude areas, or in Carb Turbo applications.

or some other Fords have the Yellow Strain Relief, its not just a Turbo Carb 2.3 thing. AMC's 258 and some 304's used he Yellow Strain relief for two years.

[QUOTE=8T6 SVO;1142813]I've got what appears to be a early 2.3 turbo motor ignition module with solenoid.

Can anyone tell me specifically what this part is?

There is a tag with the numbers EOSE-CIA and the module has a
D8AE-12A244-AA on it.

The part looks to be never used, but stored poorly for many years. I have no use for it and thought maybe a Pace car or Cobra car some where might have a use for it.

So - I'm trying to ID it, and get it to the right person.

Thanks in advance!

Confirming that the Yellow Strain Relief Durasaprk II module also controls the inputs from some of the five potential Solendoids; it operates from the five Null Knobs, or potentailly Six (6) sensor controlls that might present on a 2.3 Turbo carb engine.

Specifically, the 2.3 Carb Turbo is not a Feedback Carb 2.3 engine, has no Oxygen Sensor, and is not MCU.


The five structures of the six possible are:-

Green (RNR#1) and Orange (RNR#4) on the Top plate

Then Pink, Pink (first two) (SPARK RETARD) and the last (the 3rd) is also spark control. Pink, Pink, Yellow on the bottom Bottom plate.

Yellow is a factory set Solenoid.

Again, IIRC, there is an additional possibly Red "Sol V" for A/C Throttle Kicker to add 50 rpm to the idle speed, but its seperate from the Yellow Strain Relief Duraspark SII.

Here is an M81 engine with A/C, turbo 2.3 Carb engine in Califonia emissions with the Twin Cataylst engine standard on all 1980 Turbo's.


Image


Gere are the VECI schematic Solenoids highlighted.


Image


Everything is 9 or 12 reference voltage (12 volt is battery reference, so it can be as high as 14.9 volts, or as low as 9). MCU, EEC 1, II and III used the higher voltage to control inputs to the Duraspark II or III, or the MCU or EEC unit.


It was only The EECIV and later than 1984 stuff that had the 5 volt reference voltage. The early stuff is nigh on bullet proof, so your free to experiment.


So experiement with the inputs to the pin plugs, and measure your actual advance. You won't destroy an Yellow DSII.

Each pair consists of one high and one low limit switch.

Very importantly, the Three Pin Plug wires have been changed after the 1979 model year; D8 and D9 color codes vary.


The module is listed as a Feedback carb option for 1980 250 YFA equiped Granada passenger cars, as well as many others, 10 pages long in fact.
