Hello everyone,

does anyone know what function these wires have, and where they are connected

engine harness OBD2a


pin 6 BLU/ORN (STS)


pin 16 GRN/YEL (FLR)
pin 18 GRN ORN (MIL)




PD: they come from the connectors of the ecu but I don't know where they end

 

STS = starter signal. has voltage while cranking. Typically goes to the under dash fusebox.

FLR = fuel pump relay, aka main relay. Has voltage when the ecu decides to run the fuel pump.

MIL = Malfunction indicator lamp. aka the CEL = check engine light

 

yes thank you so much friend ... now I just need to know specifically where they are connected to leave the harness oem

 

here a picture of the wires coming out of the OBD2a ecu connectors
