Default Re: DIY: How-To Enable “Anytime” Fog Lights for $15 or Less

Pedro66, I’m afraid I won’t be able to help you on the “Bling Lights” you have installed.
These instructions will only work for the Factory Installed lights, using the Factory switch, wiring harness and Main Body ECU to control the lights.

Cutting the PINK Wire


YOU MUST CUT the PINK Wire.

DO NOT perform this modification if you are not willing to cut the Pink Wire.

Tapping into this wire, instead of cutting it will expose the Main Body ECU to +12 volts on a terminal that is designed to see only a “ground”. The effects of doing this are unknown, and probably will be “BAD”.

Please read that “Putting the Main Body ECU at risk.”

Cutting the wire eliminates ALL RISK.


Thank you for asking this question. I thought I had it covered in the instructions. I will make a change to the instructions later putting more emphasis on this requirement and why.


Fog Lights On/Off with Ignition Switch


About a week or so ago, in another thread on this forum I asked how folks would like the Fog Lights to work.

My understanding was most wanted these light to work from the stalk switch “Anytime” this Fog Light Switch was in the On Position.

That is what this design will do. Ignition On or Off, fog lights work.

Leave fog lights on when you take the key out of ignition and go to work….they will stay on till the battery goes dead.

That said, the Factory Fog lights could be made to Turn Off with the Ignition Switch,

Or

Turn Off “automagically” Two Hours after the Ignition Switch has been turned off.

Either of these two options will involve routing a second wire, from the new relay you are adding, into the cab of your truck where it will tap into an existing wire.

I’ll get this done a bit later and update the document to reflect either of these two options.


That said I have a busy day here today. Heck I’m already ready for a nap. (Don’t get old!) If I don’t get to it today I will do so this evening.
