Thanks. So the window opening was just painted black on that car? What is that color on that car? Trying to figure out what color to paint mine. It was similar to the one in the video before.

What color is that? Was there some type of gasket installed before you set the windshield in place? I thought the 69's didn't have a windshield gasket.

Thanks. I'll keep that in mind if I decide to got that route.

Yep, my has some corrosion from a leak also. Thanks for the info on those being crap. Where can you find them individually? I've searched and can't seem to find them except in a kit.

So my fuse box is in pretty bad shape. I was replacing a fuse the other day and one of the metal fuse terminal connectors broke off. I know I can buy these https://www.npdlink.com/product/repair-kit-fuse-box-terminal-8-fuse-terminals/102075 and replace the terminals, but if I'm going to do that why not replace the box with a modern fuse box? I really don't want to replace the wiring harness because wiring is not my strong point and it seems like a ton of headaches I'd get myself in to. So what options do I have. Can I do something like this https://smile.amazon.com/Holder-Indicator-Suitable-Automotive-Weiruixin/dp/B07BF2V57M/ref=sr_1_4?dchild=1&keywords=automotive+fuse+box&qid=1592654862&sr=8-4 or is there a better option?

Thanks guys. I go out and start it every once in awhile because it makes me so happy, lol. Hoping the rest of it doesn't take 5 years :)

So after 5 years of not having a running engine in my Mustang we finally got the new one going. Life get's in the way and before you know it time has flown by. Of course it didn't just fire right up with no problems though. 1st we had a bad coil which took a few hours to figure out. Then we had the firing order screwed up. It has a Trick Flow Stage 1 cam which complicated the matter. It would run on the Trick Flow and stock firing order, but was backfiring pretty bad. Took my son and I a day to figure out that the firing order goes counterclockwise, not clockwise, duh! It's actually my fault, but in my defense it's been 40 years since I even thought about a firing order, lol. I still have some wiring to clean up and a whole lot of body work to go, but it's a huge step for me and has me motivated to get it done. Thanks to the forum and especially Mach1 Driver for his awesome wiring diagram.

Great, that helps me understand the resistor. Again, thanks for your help.

Yes, the Painless comes with another fuse box with fuel pump and EEC relays. The only connections to the original harness is a yellow wire to the B+ starter relay and 2 red/green wires to the ignition (coil) switch. It doesn't connect to the ammeter that I can tell. Will damage occur if I wire it up according to your diagram and leave the ammeter? At this point I need to get this thing running. Sorry, forgot to say it's a 560 resistor. I'll have to research the terminal block. Another opportunity to learn something new :) Thanks.

Looks like are installs are somewhat similar.

That's awesome. It helps a lot. I do have some questions though because I'm horrible with wiring: The line with the fuse (Note 2) goes where? The 655R wire (red) goes to ground? What does the "V" mean. Looked at circuit symbols and don't see that. The lines that end in "NC" means what? I ordered " 1/2W .5 Watt 5% Tolerance Carbon Film Resistors" from FleaBay. I hope that's correct. I've never done anything with resistors before. Do you cut the line and solder in the resistor or remove the covering from the wiring in 2 places (leaving the wire intact) and solder in the resistor. Couldn't find anything definite on YouTube. To add to the confusion I'm installing a new Painless ECM wiring harness for the EFI 302 I've installed. Painless my butt, there is some things they could definitely explain better, lol. Thanks again for sharing your knowledge.

Mach1 Driver, Thanks, I haven't seen this one before.

Yes, I have an Ammeter (gauge says alternator). I didn't buy the PA Performance one. I'd never heard of that one until I was trying to figure tis out and read an old thread on here about how to wire that version. I have the Ford 3G. It does have the internal regulator. So the green/red that used to go to the old regulator "S" connection gets connected to the green/red on the alternator? When I eliminate the old regulator the large black wires and red wire that went to the regulator can just terminate in the harness? Anyone have an idea the best/safest way to do that? Thanks guys.

So I'm installing a new 3G alternator and can't seem to figure one of the wires. I've seen may schematics on how to do this and they all seem to be different, so I'm relying on the 1965 schematic posted. I have it all figured out except the Lt Green/red wire coming off the ASI. It says this wire goes to the "I" wire from old regulator setup. My regulator doesn't have a wire connected to the "I" connector. The only green/red wire I have on the old regulator is from the "S" connector on the regulator. Should I use the "S" wire on old regulate to the red/green wire?

I'll keep that in mind. Thanks.

That makes sense. I know that's done a lot with the newer vehicles also. I went back through all my photos and didn't find a photo of that plug. I must have thought since it wasn't connected to anything I wouldn't need a pic, duh.

Thanks for the response fellas. The car was a 3 speed manual, so maybe it wasn't hooked up to anything. Sure is chewed up though. I bought the T5 reverse light pigtail. I removed the 3 speed reverse light connector and am soldering the new pigtail to the old reverse light harness. That part is pretty straight forward. The T5 has a neutral safety switch (NSS) on the trans. I'm guessing the 3 speed did also because I don't see any kind of clutch pedal NSS switch. I'm using the painless wiring harness since I've converted the inline 250 six cylinder to an EFI 302. There are instructions on hooking up the NSS that came with the Painless instructions, it's just I suck at wiring. I'm going to have my son come over to give me a hand with that. Thanks for the help.

They're called show panels. I had the below site bookmarked because they had them for the 69, but don't list them any longer. Not sure who sells them now. https://undercoverinnovations.com/?s=panel Edit: I looked a little closer and they do still sell them. My original bookmark was dead. https://undercoverinnovations.com/product/69-70-mustang-show-panels/

Shifter light plug? Would that be a neutral safety switch or something like that? I put a T5 in and I'm still trying to figure out how to install a neutral safety switch for the T5.

Starting to reinstall some of the car and I can't remember what this blue with red strip wire connects to. I've scoured wiring diagrams and my photos I took during disassembly and can't figure it out. It's in the harness that connects to the w/s wiper motor, reverse lights and coil. It's pretty chewed up so hopefully I remove it completely.

Thanks for the help det0326. I'll cut it and see how it looks. If not I'll see if I can find the aftermarket tube.

So I'm doing my mock up for my EFI system. When I install the tank the fuel tank filler tube doesn't line up. This is a Tanks Inc. EFI fuel tank kit. So either the angle on the taillight panel that I replaced is wrong or the tank spout is in the wrong location. I have the tank pulled as far to the rear as possible. I thought maybe I could cut the filler tube shorter since the rubber adapter is flexible, but I'm not sure if that would correct this or not. I thought I read that the 70 filler tube is at less of an angle then the 69. Can anyone confirm?

Thanks. Standard 69 Mustang u-joints or something special?

Thanks. The guy wasn't ready to part out that Explorer anyway. He's trying sell it whole first. So when you measure, do you measure from center of u-joint cup to center of u-joint cup? If I measure that way mine is 50 1/2". My son is coming back in a few days, so I'll be able to get final measurements soon.

Good idea on using water. I think I'll wait until my son gets back into town and he can measure with me and the wife adding 320 lbs to the car. I did find a 1996 Explorer 4X4 four door on CL that a guy is parting out. I'm not sure that would be a 50 1/2' D/S or not though. Waiting to hear back from him about a price.
