Review on Revive GM Instrument Clusters: X27 168 Repair Kit for 03-06 GM Chevy Silverados, Tahoes, Yukons - 7 Motors + 36 LED Bulbs + Soldering Tools Included by Jerry Delic

I installed these stepper motors and clear LEDs on a 2005 Chevrolet Silverado. It took me about 1.5 hours to swap out six (6) motors and eight (8) LEDs. Here are a few tips to speed up your work and get the best results: 1. Soldering Iron Temperature: Set it to around 260 degrees C (500F). Set the temperature at the exact moment the contained solder starts to melt and flow.2. Board Heat: Do not hold the soldering iron on the board for more than five (5) to eight (8) seconds - anything else could damage the very small stepper motor pad. Use the included suction cup to remove melted solder.3. Determining the orientation of the LED: The longer lead of the LED is the anode (+) and the shorter lead is the cathode (-). On a 2005 Silverado, pin A11 (it's the pin on the top row, second from the left when looking at the back of the board) is the positive lighting voltage from the car. The anode (the longer wire of the LED) needs to be connected to this circuit. Checking for continuity from pin A11 to each backlight pad will help determine which pad the anode should be soldered to. LED Lens: The top of the LED emits a lot of light, creating a bright spot behind the sensors. The use of white paint on curved LED lenses has brought the performance of LEDs very close to that of incandescent bulbs. This is a relatively easy project if you have some electronics and soldering experience. As others have pointed out, there are some very good YouTube videos that I'd recommend watching before you start, just to get an idea of what's involved. Doing this job yourself will save you $100-$200!
