dui problem
- Thread starter Stang67

Personally I have not really read the instructions, but then I don't have a DUI 
, and I'm far from any kind of expert when it comes to electricity...but
You CANNOT use any remnant of the pink wire to feed voltage to the DUI itself. The pink wire IS a resistor and will only deliver ~6v. You CAN use the pink wire to trigger/power the relay. Mike's second and third diagrams. If you're having difficulty understanding the wiring, I'd folllow that install procedure (DUI is really pretty simple).
First, pick up a relay, install it inline of a fresh/new lead coming from your battery, meaning connnect a new line/wire to the battery then from the battery connect it to the relay then from the relay connect the new line to the DUI. Second, now hook the pink wire/aka old coil hot wire to the relay to trigger/open & close feed from the battery via the new line, meaning run the pink wire/old coil wire to the relay then from the relay connect a new black wire from the relay to a good ground (third diagram above). This will give you a 12v+ feed that is triggered/operated by your existing setup without having to modify anything at the ignition switch.
Good luck!

Am no expert on electricity either but I try that wire diagram and the first time It would fire and start up a little now it not starting at all. The second step got me lost with the whole pink wire thing. For the second step can I just run a wire to the back of my ignition switch and call it a day. 1 more question can u ground 2 ground wires to the same ground. 1 more problem am having is that oil is leaking out of were the dui is sitting in how can i stop that.
Hey Fabion,
Can you clear a couple things up...
1. Are you using a relay?
2. Is your pink wire still attached to the ignition, or have you removed it?
3. Can you describe how you have it wired right now, which wire goes to where?

Stock dizzy
DUI with relay (using the old coil wire to triger the relay)
12V-15A Weatherproof Relay (such as a headlight relay from any parts store or Radio Shack)

Did you get it figured out?
You said you have it wired just like the diagram, I'm assuming you mean the second and third diagrams above. The first diagram is not for installation it is only for reference on how your 'stock dizzy' was originally hooked up.
You should also make sure that your relay is wired correctly like Mike's third diagram above (see the numbers referenced in the diagram), the relative position is important here. Hooking the wrong wire to the wrong post on the relay will make it work incorrectly or not at all.
Your pink wire coming from the ignition switch should connect to the relay where the diagram says 'old coil Hot wire'.
No problem Fabion, cause like I mentioned I am not great at electrical, but hopefully if what I say here is wrong someone else can PLEASE correct me.
Yes, you should either splice a 12g wire to the end of the pink that is still going to the ignition switch, and then run it to the relay....or you may be able to just connnect the pink back together where you cut it and use the end that use to attach at the OLD coil and connect that to the relay...whichever is easiest. Then you need a new ground/black wire going from the opposite post/tab on the relay to a good ground.
(So you have these two wires opening and closing the relay when you turn the ignition)
Then on the other two relay posts/tabs is where your new 12g, 12+ volt (red)wire provides power from your battery to the dui. One end of the new (red)wire goes from the relay to the car's battery itself, and the other end of the new wire goes from the opposite post/tab on the relay to the dui. You don't have to use red and black for the new pieces of wire you're putting in, but it makes it easier to describe it, and follow the diagram. (So you end up with four posts/tabs and four different wires connecting at the relay, and one of them is the pink/old coil wire.)
Mike, I think Fabion had it 180* out earlier, but he corrected that and like he mentions he did have running constantly when he had power connected to the starter solenoid...assuming you have not had to restab the dui.
Fabion, I noticed your old thread where you had the ignition switch out and were trying to remove the pink at the ignition switch, and that maybe where it got a little mixed up because that is the different installation option not exactly pictured in the diagrams above. Where you remove the pink completely at the ignitions switch or bypass it for the 12 volt power feed without using a relay...But but if I were you I would just use the relay version since your that close and no need to mess with the ignition switch...again either splice a new wire to the end of the pink coming from the ignition, or just reconnect the pink and use the end of the wire that use to connect to the coild.
Again, if I'm telling you the wrong thing I hope someone will correct me.

here are some pics I took of what I did today.

$64,000 question...did it work???

I think this has gotten way too complicated. I understand most of the input you have received, even the relay stuff. But I think the solution is much simpler.
What you need is a 12V wire that is only hot when the key is on. Just like your radio only works when the radio is on. Connect the DUI to the fuse block with the fuse for the accessories or the radio. Only hot when the key is on and a 12V source. Put everything else back the way it was including pink wire.

I would check the order of the wires at the relay. Assuming in your picture that the wire with black electrical tape is the ground, and going clock wise from there, the next wire to the left should be the wire coming from the battery, the next one to the left after that should be the wire that you connected to the pink wire, the next one to the left after that should be the wire going to the dui.
What is it doing now? Are your starter and engine turning, but the car will not run? If your starter is not turning the engine...did you put everything back at the solenoid as it was? Is your ignition switch re-installed or hanging loose? You do have only one wire going to the dui itself...right?
In theory you should be able to use a 12g wire jumper(short piece of wire with clips) to jump the battery wired post on the relay to the dui wired post on the relay...and it would run till you disconnect this jumper assuming the other posts are connected correctly. Point is the order of the wires at the relay is important for the relay to be triggered properly.
If you can get a hold of a volt meter you should be able check the wired posts of the relay for voltage while someone else turns the key.
If the starter is hooked up and turning the engine, and the order of the wires is correct, and your ignition switch is working properly, you should get 12+ volts at the relay wired post for the dui. If you do, then I would go back to what Mike said and make sure it is stabbed correctly.

Vinny, I hear ya! I'm not sure, but I think he might have interpreted the first diagram incorrectly, or he was originally trying to bypass the pink all together:
http://fordsix.com/forum/viewtopic.php? ... ht=#434599
He should have never had to mess with the ignition switch (unless he wanted to by pass the pink wire...but there's no real need unless you didn't want to use a relay). Like someone else said if you use a relay, this can be set up in minutes...AFAIK.
If I understand it correctly, you just take the wire off the old coil hook it to the relay, hook a feed from the battery to the relay, hook a feed from the relay to the dui, and hook a ground lead from the relay to a good ground...voila done!
Now, I'm not sure if it matters where he spliced into the pink at this point and if that would be causing any issue, or if the ignition switch as been damaged or is not installed correctly causing the relay not to trip???
EDIT: Could he have hooked up the relay incorrectly and fried it?

When I did that way it would crank up but it would not start up.Frankenstang":1p9muhd3 said:AzCoupe":1p9muhd3 said:

Use a jumper or ONLY temporarily connect the line from the battery to the line going to the dui...if it still will not start then either the dui has been damaged or dui is not stabbed correctly.
If it does start then the relay is wired wrong or is defective/damaged.
EDIT: That is what the relay does.
