Is this
ANOTHER Failure or are you re-iterating the one you had recently?
Have to point out that was NOT a true key-switch failure (as per happens with the Twin Headlight Std's) but a bad connector socket - that is not a common failure (although it's not completely isolated either)
The 'Driving lights' option with Factory Wiring does NOT pull current through the Key-Switch.
My opinion is that a Bypass Relay kit should not be 'necessary' on 'T' model;
However if anyone DOES want it, it can be done much more simply with a single relay and minimal wiring than a full blown dual relay kit.
