Hi all. I finally got around to wiring the stang, or at least Im trying to figure out the mess. Now, Im in a quandery about the ignition wire. This this has its own wiring to the coil. It is/was wired to a switch, but with the coil, and a big electric fan, its melting these puny lil switches down fast. So, Ive decided to run the coil off of the factory wiring. Hence my problem:

I ran a Tester across every wire I could see (to see which one turns on when I turn the key to "run") The problem is, none of them light up ('cept one) The one that lights up immediately dies if the engine stops. I believe its powering the control for the alternater. If the Engine is running, then the wire is hot, but it doesnt power up while Im cranking the motor.

So, does anyone know what color the wire is that Im supposed to be looking for?? I only assume it should be coming out of the fuse box.....yeah, thats quite a mess too. Or, does anyone know of a link to a wiring diagram?

heres a couple pics to show the mess that Im talking about.

Thank you all for the help.

One of these days I'm going to load all my wiring diagrams into acrobat readerif I can get my hands on a scanner.
I have all of them in my Hanes manual.
Pretty reliable too !
If you can get a Hanes manual, probably e-bay, or an older parts store,it will make your troubleshooting 100% easier.

After looking at those pictures, I would say you need one.
Do you have access to an ohmmeter/voltmeter?
Your going to need one.

hey John, I was lookin thru summit last night for one, but none were a general fit, and none for anything close to a II. I know uh ?? IIcrazy ?? did his, where can I get one for a deal?? I take it thats what you used. How hard was it?? Any pics??

OTOH- I can keep wiring things seperately, and eventually chop out all of the stock wires. Its worked so far, but its sooooooooooooo frustrating too.

I just picked mine up from partsamerica.com (aka advance autoparts) and I believe it was $15.99.

So there ya' go.. do yourself a favor, lots of great info in there. In fact, mine just arrived this afternoon.

Jon,
No actually I am useing the OEM one. I just thought with that pile of spaghetti you may want to consider a different route. Even if you can figure it out you 'll never get all those wires under control and it will look ugly or as my friends say "ooogly!!" llol

Yep, I know I got one sumwhere. But its probably easier to buy another one than to find the one I have (another mess, different story.

Actually,

I could get all them suckers back in place and make hte harness like nothing had ever happened.

Ask Sleeper, He's an Aircraft Spark Chaser, he could probably do it better than me.

No offence , but , could you afford my rate? And could you get me the car?

I don't hold Web classes.

Pretty much what you've done is pulled the sheath and spread the loome out and want us to talk you through it.

No hugs and kisses here, only the opposite.

Buy yourself some tooling, my meter cost ~ $400 and it's only a basic unit.

Do some spark chasing and get back to us. Figure out what does what where.

Reality is a harsh mistress.

II's arent for everyone.

But then, a couple of decades ago, we quit trying to be.

Well I C the old Mark has returned. Look Freak, Ive owned about 9 IIs in the last 10 years. All have left my hands in better shape than I bought them in.
As far as stringin the loom out, It was about that bad when I got it, and pulling out the V6 damaged a few of the wires. All I was looking for was some info on which wire went to the ignition module or the coil. It turns out its a red/light green one. Thanks for the .pdf file Jeff, It was a great help. See, now theres a guy you could learn from.

Also, whats with your hypocracy, Mark?? II owners are always whining about Mustang clubs being "selective" and not accepting the II or their enthusiasts. Now your trying to turn around and do the same crap with "your" lil hobby????......wtf?

Ok, thats the last Time Ill get off topic here. Hey everyone, thank you for all the help. Ive got a few ideas to chase down tonite. Ill keep you updated.

Peace out yo
Jon
