AIC Wiring

[turbosc2]

Just got my new aic and i need to wire it to a switched ignition source and a tach signal...if someone could just save me some time by telling me where i can locate a switched ignition source and i am going to splice into the tachometer in the cluster but i don't know what wire so if someone could help me out thanks

what year/type of car? it may be easier to tap nearer the PCM for your tach source. for the ign you could just hook it to your fusebox on something not being used like the AC or CDchanger

Tach could be one of any of these depending on how your device reads RPM

EST 6X refrence- D11
EST Refrence high- D12

EST Igntion -C11 ( I would start with this one)
