    Sounds like you may have a wiring problem.

    Sounds like the factory relay might have gone bad and is staying in the on position.

    I dont believe there is a relay for the sport lights, just power to switch and then to sport lights . Switch could be bad or the wiring has been changed at one time or another

    You need to have a 12 volt test light at the least and start at the sport light switch and see if when you turn it on/off it makes any difference, if the test light lamp stays lit no matter what the switch position is in then more than likely the switch is bad. You can unplug the sport light switch and if they dont turn off then you need trace wires from the sport lights to wiring harness plug on fire wall

    You say you just put in your wiring harness in could you explain more as to the reason for install

    Yes....there is a relay for sport lamps. 1972 for sure. Maybe 1971 as well. It is located behind the drivers front kick panel.

    A 71 I worked on awhile back had the relay but it was a later year model. My 72 for sure had it.

    I stand corrected, it has been awhile since I dealt with a car that had sport lights but now that it is brought up about the location I remember. Good place to start looking

    I had a 71, and it does have the relay in the drivers kick panel. As far as I know all cars with the sportlamp option came with the relay.

    Interesting note - the wiring connectors changed for the switch from a 71 to a 72 harness.

    Yes, that is it - harness plug for the switch was different between the years.

    I would disconnect the switch and see if that kills the lights. If not, I would move on to the relay and check that.
