foglamp interrupter relay

Didn't buy the kit for 13$ instead I pulled this relay out of my fuse box and pulled a small pin of the 5 pins on the relay and plugged it back in, now I can use high beams and my fog lights on at the same time. Anybody else done this mod before?

Here's a post from 2006, from another forum, outlining the process.

Here is another modification I described earlier this year that lets them be turned on without the parking or headlamps on:



The new jumper wire is wired in between the fog lamp switch and the rear window defrost switch in the center console...

So all I have to do is splice in a wire connecting the fog lamp switch to the rear window defrost switch in the center console.?

And cut the brown wire at the fog lamp switch, from the main light switch--otherwise the parking lights will be one all the time...

I have no factory wiring diagrams for anything older than '99, however as this is all purely electro-mechanical (no electronics) it is likely the same--probably even the same wire colours...

Basicall 96-98 and 99-04 are basically the same except few differences like the body obviously. you can do the fog light relay for sure if you have a fog light button and defrost button then it is possible if i were you id take it apart and look at it see if you have a brown wire and a light blue/pink wire if not id look at you cars manual book it should have a factory wiring diagrams.

This thread is old but on new cars most high beam come on with low beams is there anyway I can make my 2003 mustang do this I hate how only my high beams come on its so much better when my high beans and low beans are on when I pull the leaver back.
