I just bought a Phantom 5" Tach and I got the wiring done except the one to the coil. Im assuming i have to splice into the blaster coil but im not sure which wire to cut, I think its the tan one with a yellow stripe, I just wanna make sure this is right!!!
Ignition coil wire legend:
Red/Lt green wire: Positive side switched power from the ignition switch. Use this one to supply power to the tach.
Dark Green/yellow: negative side signal to the TFI module. Use this wire to sent the signal to the indicator circuitry inside the tach. This wire pulses every time a cylinder fires.
Sweet thanks guys, also do you think i can mount this tach to the side of the speedo cluster bezel rather than the Dash, I really dont want to drill holes in the dash!
