my friend's GRS ecu doesn't have a led. i heard that you can jump a plug under the passenger dash, but we can not find it. does anyone know what color the wires or the plug color?

 

on the passanger side above the ecu in a little green rubber insert you will find a two wire plug



thanks jk again

 

this is really crazy cause we jumped the two wire plug and it did nothing. i am sure it is the wire that you are suposed to do it with. it came out of a green rubber boot. i dont understand, we jumped it and tried it many times. the check engine light still will not show the codes.

 

make sure it makes good conection, many times it will not touch the metal terminals...
also key must be in the ignition in the start postion (just don't crank)

 

danm. we tried a few different wires and it still didn't work. the check engine light would not flash. what the hell could be wrong. maybe the ecu wiring?
