    Tach wiring

    Ok i am currently searching for this right now, but i am having trouble with my wiring.
    I have had my car running for the winter and now i want my tach to work for events.
    I just put the new cluster into my car... for my 7k tach
    Now i am having trouble finding out what is going on with what wires go where.
    I am hearing what E36 pin 14 needs to go to the back of the gauge cluster, if i did it right it didnt work...
    I have also found something about the black wire under the glove box needs to go somewhere?
    I am really strugling with this i have been seaching all day and am obviously not in the right spot.
Working...
