The easiest way to disable the Daytime Running lights on a RWD Fleetwood is by unplugging the DRL relay in the Relay Center shown below:

Alternately, You could also unplug the DRL Diode assembly, which is located above the pedals by the brake light switch as shown in the diagram below:

Good Info, you may want to put this in the RWD fleetwood forum, where more people can find it. But won't it blow some sort of dash light if you pull the relay?

Anyone done this yet? I might do this when I install my stereo.

Let me know which method you did.

Where exactly is the DRL relay?

Bringing this thread back from the dead. :)

Ok, I went in there, and my car has everything there, EXCEPT the DRL Relay... Ugh
