MSD Shift Light..8963----Update on feedback issue

Hey guys, I'm installing the MSD digital shift light...

I ran everything properly and what not...but when I hook up the power wire to the fuse box under the dash, I get interference, so the little tach reads crazy numbers between 4000-and 6500 flashing frantically...

When I hooked it up to the fuse box in the engine bay, it was dead on...

So I need a new power source from under the dash but havin a hard time finding a diagram or whatever...

Can anyone tell me an ignition powered wire under the dash? Preferably which harness and colour?

Thanks!

Anyone else install this little bright light?

Does anyone know of a 12v power source under the dash? Besides the radio?

Update

Hey guys, just incase someone installs this in the future and has the same problems, after alot of scratching and a few talks to MSD Tech Support...I set the light up on a relay in the engine bay...this got rid of any feedback and therefore it all works properly...
