Hi hon,

Thank you for the diagrams but the url for the 77 takes me to an esnipes account create? Do you have another please?

RE: Mustang II Wiring Diagrams
strange, when i click on it i get a pop up window and it lets me DL. you could try clearing your temporary internet files and such, i'll bet thats the problem.

here, to make sure it works just copy this and paste it into your browser:

That should work for ya ;)

RE: Mustang II Wiring Diagrams
drats thinkI will have to pass hon but thank you. Everytime I click on it (your link or the other) I come up with esnipes? I dont know what esnipes is but *shrugs* that's whatI get. I am at work (shhhh, let's keep that to ourselves lol ) so our computers are cleaned nightly (and I do so at well). BUT I appreciate the effort and the sharing. There are so many wires by my feet now and I still cannot locate the fuse box. I think he (the seller) took it out. My door ajar light is now constantly on but the good news is the dashl lights I plug into the cig lighter are working better. Whatever I loosened trying to find the hi-beams works lol uh kinda. We do what we can with what we have. I think it will take me quite a while to get her up to par. Thank you again for trying. I will do a search when I get paid to see if I can buy some maybe.

Best wishes to you and happy holidays.

Thanks for the info. Recently got a '74 and I'm looking for all the infomation I can find while it's still there to find. Didn't realize how scarce '74 Mustang II's were becoming. Really appreciate the diagrams.

RE: Mustang II Wiring Diagrams
Hey, I am restoring a 1978 Mustang II with my grandfather, it is an original 4 cylinder car but now has a 351 cleveland in it.

Anyways long story short, we accidentally crushed the plastic pin out connector when putting in the engine, the one that connects though the firewall, I was wondering if anyone has a diagram or possibly a picture for it/of it, which wires go where, Because when it got crushed the wires and pins are fine but the plastic peices allowed the pins to move so they are all bunched up and its hard to figure out where it all goes. I was looking at the diagrams you have supplied but I don't think its in there, Ive been trying to find it. Still new to reading the diagrams as well.

We would just buy a new connecter but thats hard to find, if anyone has a pinout for the connector it would be greatly apprecaited.

RE: Mustang II Wiring Diagrams
which side is damaged? the fuse box side or the engine harness?

i have a V8 harness for a II if your interested.

McNamee 07-05-2008 11:36 AM

RE: Mustang II Wiring Diagrams
The harness connector is damaged, and I may be interested in that harness, I'll talk to my grandfather about it tomorrow, how much were you looking to get for it, price wise? And what is the condition of the harness?

my77stang 07-05-2008 03:12 PM

RE: Mustang II Wiring Diagrams
the harness is in great condition, which is why i snatched up on it and stuck it in a box in my closet ;)

you have a private message

Maybe someone can help me out I have a 78 mustang II cobra with a 302 motor. The electrical wiring fried out because the idiot who did my motor work ran my wiring between my radiator and the front frame of the car and with the large cam I have the vibration ate through the wires and caught on fire and fried most of the wiring to the fire wall. I wasable to get a new wiring harness from a 75 mustang II but I am stuck on one last connection which is the wire from the brain to the loom. Any suggestions on how that would be connected. Any help would be appreciated. THanks in advance

my77stang 11-06-2008 07:18 PM

sam_fajardo 11-06-2008 10:28 PM

Hey there,

sam_fajardo 11-07-2008 12:28 AM

I'm new to this so I hope you were referring to meas far ass those pics. I had my neighbor working on it and he pretty much abandoned me. I can send several of the loose wires he has going.
