Hi everyone I pulled the gauge cluster out of my 89 Trans Am however all the guides I found for LEDS were for Camaros and the clusters are different. I bought the tool to check polarity on the LEDs themselves but how do I know on the board the correct orientation for the positive and negative positions? It looks like trace 3 from the to touches every single bulb so I'm not sure if that's a common ground. Any help is appreciated.

 

In case anyone runs into the same issue I wanted to post the solution

 

Thank You for posting your findings on this, it'll surely help someone in the future whose doing LEDs in their dash.

So now, the all important questions ; How do they look? Brightness and color OK? And if you do like them, what brand/type did you use?

 

Sorry didn't even think to post pictures brightness and color were good I used Partsam 6 -3528 LED chip bulbs with their turn lock plugs. The original bulbs were clear with an orange cover for that orange/red factory color I wanted white. I put white bulbs in everything except high beam and turn signals indicators which I used blue and green but white would have worked as the indicators are colored on my gauges. These LEDs also dimmed with the factory dimmer. I am very pleased how they came out.
