My current tach is from memory a 72 911 one,looks nice but that's about it,the needle is unstable as rpm changes and not reading right.
I have a later tach which is from a 76 and has 8 pins on the back (only 3 used) can anyone tell me what pins 2,5 and 6 are for ?. 1 x purple black to engine loom, 1 x brown earth, 1 x red/black switched power. I need to know which wire to which pin,thanks in advance |

All it needs are those three connections - 12v switched, ground, and tach signal. Your problem is that it doesn't have an adapter for an early car.
Try looking for a "tach adapt" which converts the tach signal to something your tach can understand. |
