I read a few posts and skipped to this comment:

Years ago, we had an automatic bronco that ran great until you stepped on the brake pedal with the headlights on. We searched and searched. I PULLED THE DASH HARNESS COMPLETELY OUT LOOKING FOR SHORTS. Long story SHORT, it was lack of body ground. The PO had pulled the bolt off the battery cable that grounded it to the body. We figured the brake lights were grounding thru the ignition which took power away from the ignition, so the engine would stumble.

This may or may not help the OP, but it's good info for someone somewhere in the future.

Absolutely! All experiences are welcome on the forum. If it helps just one person the forum did it's job.

It's relatively straightforward, but takes a few times for it to actually become "easy" to do!
You're a contributor, so you're good there.
1. You need to first click on the "Go Advanced" tab below the reply window, or the "quote" button in the message. Which just takes you to the same "go advanced" screen anyway.
2. In the advanced screen, just below and to the left of the reply window is the "upload photos" button.
3. In the pop-up window that results, you can browse your device and double click the file, or single click then hit the "save" buttons. Multiple photos are ok with one session.
4. Click on the "upload" button in that window.
5. Finally, put the cursor where you want the photos to appear in your message, then go up to the paperclip icon and open up that menu to see your uploaded photos. Click on each one you want to show and the link will appear where your cursor was.
6. Finally just hit "submit reply" and the photos should show up in your message.

There are two or three other ways to do it as well (and they're probably all described in the "how to upload photos" thread hereabouts) but that's how I always do it.

Well there's your problem right there. Your wires get pinched when you close the hood and door!
Just kidding. Figured I had to joke about the wires hanging over the core support and hanging out the door, even if those are tool cords, test wires, or just excess waiting to get tidied up a bit.

But would that it was that simple!

Good luck on the tracing the fault still. Odd that something is connected between the ignition system and right turn signal lamp. But they are in the same corner of the vehicle, so maybe there is something tied in there that we just can't see yet.
Did you say that only the front lamp is effected? Or is the rear lamp lighting up too? I'm guessing front only, but wanted to be clear on it.

Thanks.

so yes it is the front lamp only. Once I repositioned the fuse panel it has not come back. Yes agreed it is a bit of a mess but since I don't have a hood yet, i really don't think that is the problem, but when I put it on I will make sure nothing is pinching. Looking forward to driving this again! Thanks for all the help, I appreciate it.
