Fog light question

I drive a 2006 ACLB TRD Sport and I am in the process of doing a grill mod. I want to add some duplicate fog lights on either side of the Toyota emblem just like the ones in the bumper, and have them all come on at the same time with the factory switch.

Question... can I just splice into the existing bumper light wire harness and have them work the way I want, or do I need a separate circuit/switch?

Appreciate the help!

 

Should be fine as long as you are not overloading the circuit. You could also a separate circuit with a relay, and connect the trigger wire from the relay to the existing foglight power. This way when you turn on your fog lights, it will trigger the relay to energize the other circuit.

 

this is the way you want to do it

 

Agree. Wire it this way.
