our GRT EIS with 26 as ground (since diagram (fig 52 914 install manual) shows
26 going to the negative terminal of the tach) and 13 as signal.

terminal 2, so I connected terminal 1 to +12, terminal 2 to ground & 26 of the
TCU and terminal 3 to 13 of the TCU.

be the plug from the tach coil (shown as #24) and either wire can go to terminal
3 of the tach, the other wire goes to terminal 2 of the tach which also is
connected to ground. Terminal 1 of the tach connects to +12.
