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 |

Thank you gentleman for your replys.
I did search for a very long time and found diagrams but they don't match the wires to the numbered pins on the tach as mentioned they are only a represention of one. My ignition is Pertronix ignitor II and Permatune blue CDI box it works very well. I contacted Bob @ Ashlocktech and he confirmed my initial set-up of the tachadapt ,I have no history on the tach I'am running however. I'am merely wanting to test the spare I have against my current one and as the spare is a match for the CDI i'am fairly sure I won't need the tachadapter.  The top pin on the tach is marked as #2 and the 2 lower ones are #5 and #6. Hope this is more helpful information,thanks. |
