Vintage air ecu help
 

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

Would be useful if you posted the titles of the columns and the rest of the table. It is not clear if the 10k resistor is already present or needs to be added.

You need power. I would pull it off the wire going to the binary/trinary switch, not after.
