Wiring up the alternator

GENERAL
1

Hi community, I am rewiring my Westfield Mega S2000 (Honda S2000 engine, 2005 F20c) with the PMU24, ADU 7, Keypad 13 & 2 rotary switches, and EMU black, progess is going well and now onto the bits I am unsure about. The alterator is only has 2 wires in use with the old Omex ECU, 12V ignition and warning light.

How best to wire this in now,

  1. 12V from the PMU when the the ignition on button is pressed on the keypad
  2. warning light - should this be an aux input to light up a warning light on the adu via canbus but I think the output is 12v?
  3. I have already set up a warning in the display to come up when the battery voltage is low.

any advise will be a help.

Thanks

Phil

  1. I did same in my civic.
  2. No other wire, just monitor the voltage in ADU and light a warning light if battery < 12v. (That’s how I did it)
