I took a few of my gages out to install a wired remote in my dash. While I stored my gages I must of bumped a few of the config switches on the back of the tach. I tried to look everywhere for the right configuration. If anyone knows could you please share the knowledge? Im talking about the small 8 switches on the back of the tach to correspond to your engine.

I have a 1993 271 and have the 502 MAG EFI engine.

Any info would help greatly as I am going crazy over this.

Thanks!

napa auto used to sell vdo marine, maybe they could help out
