Hello, looking for a little help on installing my analog gauges (tach and temp) on my 2000 P3. I have connected according tot he wire color codes and they not working at all.
A little background. Recently my BP101 went toast, so picked up an A10 and Mercury Admiral gauges and started replacing all the old nasty wiring. Also just replaced my ’99 200 EFI with an ’01 200 Optimax.
For the tach, I have tried connecting the purple wire coming from the key side as well as the purple coming from the harness side to the I on the back of the gauge. Same for the ground (black). Sending is connected to the grey wire from the harness. It seems so basic and its not working, and ideas?
