Fog Lights Mystery
Would anybody be able to help me understand a mystery with my 2011 JGC Laredo X fog lights.

I have installed auxiliary fog lights, and connected them in parallel to the existing fog lights (PSX24W), so the auxiliary lights could be operated by the original fog light switch. (and should be on when the fog lights are on)

When the wiring harnesses are disconnected from the original fog lamp connectors the new lights are working fine. However, when I connect the wiring harness to the fog lights, all 4 lights are not working.

Any idea what might be happening?

Re: Fog Lights Mystery
Overload of the circuit? Have you changed the fuse to match the extra voltage draw?

Did you use a relay to trigger the auxillary fogs?
Doesn't sound like you did...... That's the right way to wire them, use the OEM fog hot lead to trigger the auxillary fogs thru a relay. :thumbsup: then you can use your OEM foglight switch to power both sets of fogs with no power issues.

Re: Fog Lights Mystery
Many thanks for the good advice
2nd circuit with a relay solved the issue
