Ok, I have a 1976 porshe tach that i want to put in my 71 bus, i got it for cheap so it works, I need to know what goes where, there is a +12, 1, -, I think i have a good idea what goes where, but let me know.
Thanks

Connect the "+12" to a positive 12 volt power source (use an accessory fuse that is switched with the ignition), the "-" is the ground, and the "1" is the signal - connect it to the negative side of the ignition coil.

Cool thanks, got it all wired in and it works great.
