Harness location where the red, red/yel wires from auto light-off control module join with the red/blk, red/blk wires of the high beams.

Temporary DRL delete. This method is the same as pulling the hi-beam fuse, so you do lose operation of the hi-beams.
The switch makes it so you can easily switch the hi-beam circuit back on, having the normal DRL and hi-beams.

A bunch of parts.

All assembled. This whole thing is a test run, so the switch is taped to the relay for this stage.

Everything set in place and tested.

All done; this set-up is only temporary.

Did some testing on the DRL circuit, and it appears to switch polarity when changing from DRL on to off (headlights on).

Engine running, DRL on.

Engine running, DRL off, hi-beams on.

Engine off, DRL on.

Engine off, DRL off, low-beams on.

Engine off, DRL off, hi-beams on.

With the battery removed, yoo can see and and get at the rubber grommet to run the wire through the firewall.

"DRL Switch" in the cubby; I will work on a proper mount for it.

To summarize what this does....
.

DRL Switch
POSITION	RESULT	SIDE EFFECT
On	DRL's work as normal	-
Off	DRL's do not illuminate **	Hi-Beams do not work

** the circuit is still on

Minimal clearance in the cubby is limiting where I can have the switch, so I used some doublesided tape and stuck it in the left lower corner.

I made this plastic switch holder for the cubby, but the adhesive wouldn't hold and it ended up falling to pieces as I installed it.....

Back to what I know; 1" square aluminum will do the trick.....

All done.

New "control box". This will replace the relay and fuse holder used in the above test run.....

To get the Piaa relay as small as possible, I cut off the mounting tab and wiring connector lock tab.

ABS enclosure.

Apparently I didn't get an image of the Pico fuse holder or the building process. So, moving forward, I cut a hole in the enclosure and epoxied it in place, then made up the wiring pieces.
