I have a Honda 99 BF90, and picked up a Honda digital tach from a used marine store. The two plugs on the back don't match anything on my wiring harness, and I looked up the gauge and it says it's for 2005 and up Bf115 to BF225 Honda. What I am trying to figure out is if this thing is more or less a display for the ecu, or could I cut of the plugs and wire it to my tach, temp, oil, trim? It's probably a reach, but it would be nice to have all that info in one gauge. Thanks.-Taylor
