Thanks Bill, that's helpful, I'll reach out to them. Have a great day.

Good morning, I just rewired a 69 Shelby GT350 that's been sitting for about 6 months.  I've been test driving it and all systems were working great until I turned on the air conditioning.  The belt screeched, motor stalled and there was smoke under the hood.  I lifted the hood to find a yellow-ish oil that sprayed on the left valve cover and exhaust manifold. Attached pics show the general area of oil and a small orifice that I suspect is where the oil came from but not sure.  I'm no a/c expert and wonder if you might know what I'm up against here? By the way, I turned off the ac switch and motor starts right up, runs great.     

Issue found: Faulty light bulb. It's a brand new LED replacement (1004 style) that's supposed to get + and - from the 2 bottom contacts, with the metal body being separate or isolated from the electronics.  In this case, the LED was made incorrectly and was getting its ground from the metal body along with one of the bottom contacts.  Since the bulb socket is grounded, that explains why the light wouldn't turn off.  Hope this helps anyone that runs into this issue.

Hi - I have a '69 Shelby with a glove box/map light that won't turn off.  It has a switched ground to turn it on and off by the glove box pin switch and the mechanical switch on the light housing.  The thing is, it works perfectly when the clock dash-panel isn't fully installed (wired but pulled away from dash for testing). Once installed, the light is always on because it's being grounded by the metal construction of everything around it, screws, metal clock panel, light housing, and socket.  My assembly manual doesn't specify but I'm wondering if there should be a gasket or isolator somewhere between these parts?  Anyone else run into this problem?

Yes

Great, thanks for your help!!

Gotcha, are you referring to something like these?

1969 GT350 with A/C:  How is the Engine Gauge Feed Harness and a/c wire secured along the valve cover leading back towards the firewall?  My assembly manual is to faded to see how these are managed.  I've heard there's a single rubber-coated clip fastened by the center valve cover bolt.  Does that sound correct? Thanks and have a great day!

Thanks a lot guys, that helps explain quite a bit, cheers!

I'm chipping away at 55 years of wiring butchery on this '69 Shelby and found this resistor mounted inside the engine bay.  Someone hacked into the dash harness and ran a couple of pink wires to it.  I'm guessing this wasn't original equipment? I'm hoping someone can confirm. 

By the way, one of the pink wires is spiced into a red/green wire leading to the ignition switch, the other is spliced into a brown wire that shares the same plug terminal with the factory resistor wire. This car has a tach and it looks like the factory pink resistor wire leads to it. 

Yes exactly. You removed the original green/red 16 gages. Fold it and tape it. Install the intermédiaire one green/red 14 gages wire at the brake switch as 6 bulbs brake light pull more load.

Ok, thanks!  I was wondering what was the point of using a different wire but it is heavier gauge and with the Shelby lights, that makes perfect sense.

Ok, just to clarify, you're saying to take the green/red tracer wire from the intermediate harness (1) and put it in place of the green/red wire (2) that's in the stop-lamp switch plug (coming from main dash harness). Would I then just tape off/clip the unused green/red wire from the main harness? From what I can see on my schematic, this original wire (2) would be pulling power from the headlamp switch.  I take it that the intermediate harness green/red wire will provide power from a different source?

Interesting, thanks, I'll have to check into that.

Hi all,
I'm replacing a "69-70 SHELBY DRIVING LIGHT UNDER DASH INTERMEDIATE WIRING HARNESS."

The original intermediate harness that I'm removing from the car has a green wire with red tracer connected to the brake switch plug.  The new intermediate harness has this same wire, green with red tracer (maybe 14 gauge), with a 90-degree spade terminal.  I'm attaching a stock photo of the harness showing the wire.  After going through numerous schematics, I can't confirm that this is correct?  I've also replaced the main dash harness that already has the brake switch plug wired up to both terminals (solid green and  a green wire/red tracer, 16 gauge).

I am pretty sure Shelby did not move the taillight harness, so there has to be an extension.

That's what I'm starting to think too.  The harness manufacturer confirmed that it's made correctly per their specs. 

It's a '69 Shelby Convertible.  Here's the quarter panel, just before I removed it.  You can see the light towards the bottom.
