Thanks for the info. The wifey had a disc removed from her neck the other day and taking care of her has really cut into my troubleshooting time, lol! She's getting better, so enough of her and back to the Mustang. lol!
I was able to remove the firewall connector and fix a couple of the wires. There was a green/black wire that ran to the headlights that was bare on one side. I also found a broken wire (black) going to the quick disconnect for the right front parking light. Parking light still worked though. Kinda of weird.
But, this still has done nothing for my original problem of the turn signals not working. Brief recap - replaced switch, no luck. Blue wire that has power coming into the switch has power until I turn the turn signal on, then power drops off. The blue wire is orange/yellow on the other side of the flasher and comes from a common point. All other items that run on the common point seem to work fine. Any ideas where I should go from here?
Another issue I noticed is that there is a pink wiring coming from the ignition switch that goes to the coil and and the starter relay. With the ignition on this wire is getting pretty hot. Not so hot I can't touch it though. I read this is a resistance wire, does that mean it should get hot?

I have some bare wires very near the square firewall connector next to the master cylinder. One of them (brown wire) goes from there to the starter relay and is giving me high resistance. Does this connector just disconnect from the wall or do I need to remove something on the inside fo the car? Can I replace the wires coming out of it? It's crazy how many bare/rough/stripped wires I'm finding on this car.
On another note, my washer pump problem, was solved with a new wiper switch:clap: Still fighting the inop turn signal problem though.
Check out the photo from when I first brought the car home. I was troubleshooting wires and decided to eliminate the "wires to nowhere". Well, I got to looking at the silver box (circled) on the side and after some wire tie cutting and exploring found that this box did absolutely nothing. The 2 harnesses coming from it were plugged into each other. It was not plugged into anything on the car. WTF! I removed it and had a bit of a laugh. I know I had one of those on an old Ford truck. I think it was some type of ignition box. Why it was on the Mustang??? I will never know :scared:

I have some pulleys for your 302. I'm parting out a few 69 & 70 coupes.Where you located?
-
I had a friend over today who is fairly good with wiring. He didn't have time for in-depth troubleshooting, but we did notice something else today. The wiring harness above the radio gets pretty warm when the ignition is warm, but the others stay cool. This indicates a short right? If so, would I expect to find the short in that wire bundle? Both the blue and orange/white wire that connect to the flasher run through that harness. BTW, I installed a new flasher just to be sure with no luck.

Yep, 100%. Thanks Tom, you've been a big help.

Geez these electrical problems are killing me. I replaced the switch and the turn signals still don't work. The blue wire in the connector powers the turn signals and I have power there until I turn on the turn signal, then I lose power. If I jump the red/white (emergency flashers) wire into the blue wire the signals work no problem. I have swapped the emergency flasher with the turn signal flasher with no luck. They both have the same part number #552 and Advance Auto lists both emergency and turn signal as 552, is this correct? Also, in the diagram the red/white wire is black/red, but mine is white/red. Is it normal for Ford to change the wire colors different than the diagram?
There is a junction in the diagram that appears to be where the turn signal gets its power, but I can't find that junction. It appears by looking at the actual wires that the turn signals get it's power from the blue wire that runs to the flasher and comes out the other side orange. This orange wire is connected to a junction that has 4 or 5 wires coming out of it (one of those coming from the washer switch which could be related to my washer pump not working).
Any ideas? This is getting on my last nerve:surrender:
-
Thanks guys, great suggestions! I'll give them a shot.
Tom, I replaced the entire switch because you mentioned that the cam was only a fix for a turn signal that wasn't clicking into place. My issue is no turn signals. Thanks again for the help!
Still haven't re-attacked the wiper switch, I have it on ignore for now.

I ended up buying the entire switch to fix my inop turn signals and now I need to transfer the connector to the new switch. I went to Advance and Autozone to buy the tool to remove the old wires from the connector and they don't carry them. I've seen them online, but for the life of me can't find one now. Anyone know what the official name of this tool is so I can search for it? Or is there a home remedy for releasing these wires from the old connector?
Thanks.

Mine was originally Silver Jade, then Yellow and now Copper.
I would be willing to provide all the info.

Hmm... I see the one you posted now. When I clicked on it the first time it took me to their search page.
-
Is this the one you were trying to post?

It doesn't look too bad, but could be better.
-
Great idea Tom, I'll test the switch just be sure.
Thanks!

I do see where you would need to occupy your mind on something else. Good luck to your Dad and your car :tongue:
-
I hope your Dad recovers well. I wouldn't be able to look at my car if something was wrong with my Dad. Good luck!

OK, I got back at it today. Thanks for all the suggestions. I disconnected the harness connector at the switch and my continuity from the connector is good is good all the way to the pump connector (no resistance). On the switch connector I jumped the green and the orange/white wires and the pump runs. This is telling me the switch is the issue right? That''s how I see it, but I just wanted to bounce it off the forum first.
It's funny because I originally ordered the variable wiper switch made by Drake and when I installed it nothing worked, no wipers or pump. I recently sent that back for refund and would recommend that people stay away from that switch.
Thanks for all the help :)

Also, I have been noticing a small puddle accumulating under the rear end after each time I push it in/out of the garage. It's a 9''. I haven't done much investigating but I believe it is coming from the front of the diff. Any ideas?If it's leaking where the driveshaft enters the 3rd member it's the pinion seal. Pretty easy to change if thats it.
-
Well, I cleaned up the connector and it still doesn't work. With the key on and the car just sitting there I get 11.2 volts from the connector, with it running I get over 12 volts, which should be more than enough to run the pump. Connector has power, pump works, put the 2 together and nothing. I'm chasing my tail, what am I missing?
-
Thanks, I'll give it a shot.

When I bought my car the reservoir and washer pump were missing, so I replaced both. The pump won't operate when I push the washer button, but it will if I jump a hot wire straight to it from the battery. I have verified power and ground at the washer pump connector. Best I can figure is it's not getting enough power to run the pump from it's connector. What would cause not enough juice to flow through it's dedicated plug? :surrender:
-
Here are a couple more photos before the rebuild.
-
It's really hard to tell from your photos. What is the rod sticking out of the left side of the pedal? Isn't that part of the pivot that should face the other way and go through the pedal support?
I just did the rebuild on mine and here is what it looks like out of the car, maybe that will help.
-
Has anyone ever replaced just the turn signal cam VS the whole switch? How did it go? It's crazy how much the whole switch is, but then again I haven't troubleshot/removed the old one to see if that's the problem. Just leaning forward a bit before I jump into this one.:001_smile:
Here is the cam I was thinking of:
-
Jeez, I just realized that those ports are for transmission OIL, not water. I was thinking the coolant/water would leak out those holes if not plugged. Man, I should think before typing.Anyway, is it considered bad form *not* to plug transmission cooler holes for a manual tranny car? (Hoping to salvage my dignity by asking the question).
Tom
Tom, I also added an aluminum radiator to my car and had the same question. I went to the local parts store and asked the guy about plugs for the cooler holes. He said they didn't carry anything like that and said you would probably end up adding a dedicated transmission cooler anyway if you added an auto. I'm sure I could have found plugs if I looked hard enough, but I'm not worried about just leaving the hopes open. If you are are worried about someone seeing empty holes, by all means plug 'em up, otherwise I see it as no big deal. :euro:

Firewall Connector

The pink wire is a thickly insulated wire that has about the same amount of actual wire as 16 ga wire. It also doesn't have copper wire, it's a silver wire. At some point the PO used a butt connector and replaced the last 12 inches of wire going into coil with regular 16 or 18 gauge wire. I thought maybe the different type wire was the cause, but the wire on that side (coil side) of the quick-disconnect doesn't get warm at all. If it was standard wire I would try to replace it, but since it's "resistance" wire I'm not sure if it would screw something up.
