Using Tt As A Voltmeter?

[Sambo33]

hi all! my situation is my battery light is not working, so i need a voltmeter. i have an Apex (pen-style) turbo-timer (not-installed) that has a battery voltage feature. i already have a turbo-timer inbuild into my alarm, so i do not require the turbo-timer features. so my question is -

how do i install the apex timer for use as only a voltmeter?

the main wires it has are:

Red - 12V constant (obviously hook up to constant battery source)

Black - Ground (obviously hook up to earth)

Blue - IG2 output?

Green - IG1 output?

do i need to wire into the ignition harness? or could i just wire it anywhere?

can i only use 1 of the blue/green IG wires? or are both required?

thanks

Tha Apexi instructions say that some cars require 2 wires to be energized when the key is in the "ON" position, however I believe that skylines only need 1 wire to be energized when the key is in the "ON" position.

Therefore Red = 12+ Constant

Black = Ground (-)

Green = Ignition

Blue = Accessory Wire (Apexi manual states that this wire will just go to a wire normally energized in the "ACC" position.

Hope this helps.

Thanks for the info Nath! i just hope it doesnt try to still use the TT mode when i turn it off? Im thinking about splicing it into the CD player wires (12V, Earth, & Green wire to ACC), so that way it might only use the Battery mode?

cheers
