While attempting to rebuild my wiring harness to my specs, removing all I don't need, and simplifying, I found a lot of switches had a signal sent to the ECU when triggered. Example: the rear defroster sends a 12v trigger to the ECU.
Why?
There are a few others as well. Is this a stall prevention system (ie trigger tells ECU to up the fuel/air to prevent a stall)? I know I've turned my highs +extra offroad lights, rear defrost, heater to high, stereo as loud as can be, and the engine bogs down, but recovers.
Would the load put upon the motor from the alternator cause the motor to die if it didn't know to up the fuel?
Edit: Also, if this is the case, would putting switches downstream of the trigger to remove the electrical load, but maintain the "phantom" trigger, cause a enrichment of my af ratio?
