I am in the middle of installing an afc into my mk3/1jz supra. The apexi instructions list 2 wires to tap into on the ECU for tha tach signal. It doesn't say if I splice both into the grey wire for the afc or if I just use one of them, or if I use one of the other wires. If anyone has done this and can help-I'd appraicate it-Thanks
