This info is in my Mera build thread but I thought that people that are not reading my thread might be interested in this since it is not Mera specific.
I have always thought the Fiero gauge cluster looked incomplete with the unused unexplained blank panel on the opposite side from the odometer. Looking for ideas I saw a fellow forum member 30+mpg put an air-fuel gauge there and I really loved the look but I was unable to find an air-fuel board I could adapt to fit. However looking on eBay for hours I found this voltage gauge that was exactly the size of the spare opening in the Fiero and it was super $13 and even cheaper if you are willing to wait for it to come from China, so I went ahead and bought it.
Here is the link to buy one if anyone is interested.
http://www.ebay.com/itm/282...e=STRK%3AMEBIDX%3AITThis is what it looked like when it arrived. It is a little goofy looking and too thick in its original casing but that is no problem because I was not planning to use the casing anyway.
This was the hardest part of the whole project. It has 4 screws in the back, I thought 'awesome this will be simple', I was wrong. After removing the screws I found it was glued together extremely well, it must be water proof. I broke 3 xacto kinfe blades cutting it open. Once inside there is a large blob of hot glue that I carfully cut through. Then I was able to carefull pry the board out only after I cut the case to let the power cable to come out. Once out I wanted to see if I could get the lense out, I figured if I break it I will use tinted plexiglass. I just used flat head screwdriver and push hard on both ends back and forth until it popped out.
Now that it was out I did a trail fit and was happy with how it looked.
People following my build know that every modification I am doing I want to be able to easily reverse because I think the Mera is a special car and I plan to take all my mods and Ferrari stuff off in the future. So I used Gorilla Tape to hold it in place. This picture was the trail fit, I actually did a better tape job when I did the final install.
Next I made a harness for it so I can quickly and easily remove the gauge cluster. I covered it in heat shrink and it made a nice harness. In the car since my dash was out I routed the wiring through all the factory wiring brackets and attached it to the switched power lead on the stereo harness since I do not want to cut any of my factory harness.
Here is the finished product. The angled line you see in the lense is a refection of my arm. Also the car is running but none of my other gauges are currently plugged in since I am still doing dash work and the factory pastic gauge wiring doesn't hold up well to repeated plug and unplugs.
Here is a quick video of it in operation.
