Can someone please guide me as to what pin/wire to tap into to wire in an economy mode light?
The ECU in question is a P2J-J61 OBD2a running a D15B 3 Stage engine on a Civic 99 AT.
I have already tapped into A8 (green/yellow) for a VTEC indication light. The only other option that makes sense to me is that of VTM (VTEC pressure switch) at C15. The IAB pin (A26) doesnt seem to be used in a civic. I am using the following pinout diagram.
