I still have to retrofit a 1st gen 4runner deck lamp switch into mine, but I got to look up the wiring diagram/colors on the switch.

 

The lights draw more than that; but, by using the relay, all of the strain is placed on the relay and not run through the switch.

All the dash switch is doing when wired to a relay is activating the relay and using enough power to turn on the led on the switch.

 

That makes more sense, it almost sounded like you had your lights wired through a 3-5 amp fuse.

 

no way haha, the small fuse is just to protect the switch itself. You run a 20 amp or whatever u need from the battery to your relay.

 

savage offroad also sells the factory switches btw

 

If you are running a hard-line straight from the battery, you should always use a fuse. If not, you are just asking for shorts/fires, especially if the wires are not secured or are rubbing against abrasive objects.

The only time I ever wire something without my own fuse is if I know what +12 source I am tapping into, as it should be protected already by the factory fuse box.

 

Also, this may help:

reference the picture in post one to see the order of which I am speaking, but these are 3 pin switches... I'm not aware of any OEM 4 pin switches?
