DIY: Instrument Cluster Mod
I got side tracked doing other mods (while dismantling my dashboard) so the IC came out and I decided to mod it.
Anyway, this is NOT meant to be a thorough DIY because if you're about to tackle this project, you probably have advanced technical knowledge of cars, car systems, LEDs, electronics, soldering, etc...
As always, I take NO responsibility for any damage, injury, harm, destruction, failure of your mod endeavors. If you do embark on this mod, keep in mind the cluster is ~$500 + the labor to get the keys and cluster reprogrammed at your dealer if you break something. P/N GJR955471D.
Numbers correspond to pictures since I maxed out at 10/12 pics:
1 - Start here... White needles, white cluster.
2 - Pull main bezel off, it pops off along with the upper half of steering column.
3 - Use a cloth or something soft to protect the face of cluster from scratching on steering column and lay it face down. Unclip the single connector on the right side, then GENTLY finagle the stupid wire retention clip out. (If you pull too hard you'll mess up the soft back plastic, pic 6)
5 - Here's the cluster without the clear plastic front cover. To remove the needles, you will need to pull straight up with a LOT of force. DO NOT wiggle the needles out or you'll mess up the magnetic servo. (Oh, you'll probably need to reset the needles to 0 when you're done... good luck*)
6 - Back of cluster, you'll need to pop this off as well, but make sure you hold the PCB so it doesn't fall out or break the needles on the other side.
7 - In case you guys were wondering what lights you may encounter...
9 - Here's a naked board. The LEDs in question are to the top left of where the needles go.
10 - Left side LED replaced... kinda messy, I need a better soldering iron.
11 - Test run. Works!
12 - Put it all back together and enjoy the end results.
Note: You can change the back lighting and needle color to whatever you want (except RGB) assuming you get the proper SMD LED. I had some leftover bulk SMD LEDs from some other project so I have no idea what specs they are.
*If your needles get all out of whack.... i.e. If 0 is below the printed 0, move needle clockwise all the way until resistance is felt, then 'force' it some more, then go back counter-clockwise until it stops on 0. It works for the opposite direction as well.*
