Hey,
I'm trying to wire my ecu for the a/c idle bump signal. vintage air has given me the instructions for an ecu that need the a/c on signal as 12 signal or if i need a ground signal.
just trying to figure out what my AEM Infinity 508 needs. Here is the description of the pin I will be using in the harness. Do i need power or ground signal?
I'm assuming ground signal but I'm wiring inept.
thanks in advance
