Well it wasn't on my MSP, but I have to post. So the Evo I bought came with white faced blue/green light up gauge faces. I finally got sick of them and decided to take them off.
First of all it's 10 times easier to get the gauge cluster out of an Evo than it is for an MSP. So I got the faces off, put the cluster back in. I decided to reroute some of the wiring for the wideband and meth controller. I'm pulling off a panel and I see currency behind it, a 50 dollar bill! But wait, there's more than one! So I started ripping the panel off all excited. Turned out to be $200 bucks hiding behind my dash, 2 $50's and 5 $20's.
My only guess is emergency cash stash spot? The panel comes off by taking two screws off and popping free a couple clips so it's not all that hard to get to. Or maybe one of the previous owners was a drug dealer, who knows. Time for me to go buy some new gauges
