Are yours not working?
They are connected through the steering column, through the bulkhead connector, utilizing the same connector as the turn signals, however they have their own wire, usually marked with a tracer,
different from the front side marker. Check your FSM to see which color it is suppose to be. The light is powered by a #1293 style bulb and shine bright when on. If yours aren’t working, check the bulb, check the connections to the lamp. Test the bulb contact with a test light or multimeter etc.
Finally, A common problem that occurs with the cornering lamps is a loss of their ground. They do not have a dedicated ground wire like every other light on the front end. They are grounded through the bulb socket and into the Cornering lamp housing, into the fender. Make sure the metal there is clean and rust free. Running a jumper wire from the battery and touching the socket housing is usually a tell-tale sign.
They remain on steady while the turn signals are flashing. They use a special turn signal switch with extra wires. I believe the aftermarket turn signal switches may have the extra wires for the cornering lamps.
Yes they have the special wires - be sure to select the correct one as there are 4 variants of the Turn Signal Switches.
