If I hook it up with just a TOD(light blue/silver) in wire...... and the TOD(computer side of Light Blue/silver) to computer wire the TOD will disengage and the Check TOD light comes on and flashes...



but, if I ground the switch to make the LED light up...TOD WILL NOT DISENGAGE and I get a clicking/humming noise some where on the passenger side in the dash..... and go figure no check TOD light flashing


why is that?????
