I'm new to the site and seen several old how-to's lacking pictures but look like they were very well done. I hope your pictures stay up and don't disappear.
HOW-TO-> fix 03-04 SVT Cobra Gauge lights

Thanks Caveeagle for an awesome write up. I just completed this tonight and my gauges work like new!
Red2003Cobra...you were right the second time around, although the inverter is probably toasted. I got a little hung up on that step as well. Basically, there are the two white wires that you clipped off the old inverter. These will be connected to the two black wires coming out of the new inverter (which used to lead to all of the accessory connections that you clipped off). What he was saying originally is that it doesn't matter which of the two black wires attaches to which white ones...as long as they're connected. Hope this helps!

Yeah, I'll give it another try, since I think I see the error in my ways. New inverter is ordered and on it's way.
Ok, I re-wired a new inverter and it works perfectly. Thanks for the great write-up and advise.

I have not noticed this. Did you solder or use crimp connections?
You may want to call speedhut and see if it might be a defective inverter.
So I did this and it didn't work question on the wiring did you tie both blacks together then connected to the white? Or just one of them
There two sides to the speedhut inverter.
Side A: is White and Black
Side B: is Black and Black
On Side A: The green & Blue wires (on the cluster) are spliced together and connected to the White wire (on the speedhut inverter). The Black connects to black.
On Side B: You just connect each of the black wires (speedhut) to a white wire individually (on the cluster) They are reversable, so it does not matter which one goes to which.
The loud buzzing your hearing is the frequency. The frequency is how the inverters can change colors. The cheaper speedhut on is one color only though. But they work by.....frequency of electricity= color Voltage = brightness. You'll notice when you change colors on the upper model inverter the buzzing will change tones.
After all of this I have not seen how/where to buy the inverter other than speed hut
Google is a marvelous tool. 
Gauges, Custom Gauges, Tachometers, Speedometers, Shift Light, Pod
They rep I spoke with seemed very knowledgable. He was even able to discuss the repair of by '04 Cobra cluster.
They do offer other types of inverters. I know there is even a version that will allow you to change the color a bit. I just went with the simple one. I wanted it to all fit in the original cluster and look as stick as possible.

Requesting a Mod. to move this to the "how-to" section for future reference.
Sub.
looked through the thread, any part numbers? my dash went out last night and i want to fix it.
The part # for the one I used is: "A-INVERT-04"
There are others that will work, but that one seemed to be the best option, and will fit in the stock location behind the gauges.
