Is there a good power point on the outside of the firewall for connecting daytime running lights? If possible, power should be controlled by the ignition switch. DRLs will be LED.
I don't want to have to poke a hole for access to the glove box fuse panel.

Steve,
How about the center (alternator) post of the splitter. The lights will be on as long as the engine is on, be sure to put an appropriate size fuse in the line.
Just a thought.

Thanks, Adrien
I don't know why that didn't pop into my head - engine on / lights on engine off / lights off.
I guess this is an appropriate use of "Duh"

Steve, Very easy access thru the firewall in the upper passenger side of the firewall, by the underhood light. Access the passenger compartment side by removing the glove box and reach inside the right side. Putting a piece of small diameter dowelling or wire into the grommet will help find the interior end.
I'm using this to pass my heavy 12v wiring for my Ham Padio.
You could use the yellow wire on the heater block to trip a relay to turn the lights on and off with the operation of the engine.

Steve,
I'm not sure how you are wiring your lights to make Day-time Running lights, but its very simple using a horn relay.
Connect one side of the relay coil to the center of the isolator to get the "engine running" power. Connect the other side of the relay coil to the high-beam light power wire. This way with the engine running and the headlights set to OFF, the relay coil will get its ground through the low resistance of the high-beam headlight filament. When you turn the headlights ON and switch the high-beams ON, the relay coil will de-energise and switch off power to the low beams. You don't want both high and low beam filaments on at the same time.
Connect the common relay terminal through a fuse to battery power and the Normally Open to the low-beam light. You could get power for the Low-beams from the isolator center terminal and get a higher voltage than battery, but for Day-time running lights you don't want them brighter than normal.
