Just installed this glow gauge on my 96 talon. Previously didnt have any lights working on the dash, went ahead and purchased the rear cluster bulbs #74 and replaced each one of them. After that only thing that Had turned on were the cursor markers on the cluster. Went ahead and got the gauges off ebay and now when installed only the hot/ cold gauge and the fuel gauge turn on. The rpm and mph remain off. Checked fuses and bulbs everything seems to be ok. Any idea what could be causeing the issue? P.s Sorry for the long post... appreciate the help.

I would take the cluster back out and make sure everything is plugged in good. If that doesn't fix it I would double check any wiring you spliced into for an open.

Havent had the time to get around to working on the car till today due to work nd school. But i went ahead and removed the aftermarket cluster and replaced all the bulbs on the instrument panel with led bulbs. But for some reason only a few bulbs light up and are located on the right side of the mph gauge. The rest are off.... Any idea what the problem can be? Maybe a faulty cluster or could it be something else

it sounds like a faulty cluster can you check to see if the board has any cracks. the eBay seller might have a warranty and should be willing to help

Just FYI, LED bulbs have a definite positive and negative pole so try turning the bulbs that won't light 180*. It might be that they are just in backwards. Hopefully anyway. I would also check the ground circuit with a multi-meter for continuity.

+1 on the LEDs being backwards. Another thing I ran into when putting LEDs in my cluster and HVAC was one had a manufacturing defect so it wasn't making good contact and wouldn't light up. I spent about an hour putting it in, flipping it, and trying again. Once I changed the bulb it worked fine. I doubt that that many would be like that in your cluster but it's still something to check.
