Well, it should not be too,too difficult. Since I don't have my Titan yet I can't give you exact instructions- but this is how I would do it... here goes.

I would want to have the option of turning on/off the fogs to work as daytime lights AND using the regular stalk switch on the steering col.

Easiest thing would be to get a wiring harness for fog/driving lights. Visit the Hella web site or a dealer site, you can buy a complete harness +relay+ switch setup for not too much $$$.

The harness will have 12V battery lead, 2 pairs for the lights (splice into fog wires), Ground, Relay 12V and switch pair. That's all straight forward.

The key would be WHERE you tap in the 12V relay line. Maybe in the fuse panel under hood or dash. You have to find a tap point that will energize the relay when you turn the ignition ON. Something non exotic like wipers etc. (don't hook it to your ABS or computer)

The power needed to throw the relay is very small < 1/2 amp.

The switch can be left under the hood, under the dash or you could get another Nissan switch and use one of the switch blanks on the dash.
