    For that you should've gone with an add-a-fuse.:rofl:

    Because you did the same thing by tapping the constant power of the Horn relay...

    not trying to be rude or anything I’m trying to figure out the specifics because I didn’t “tap” any wires just using a blade connector genuinely asking for information

    Look at the drawing I posted. It shows the slots where the relay is inserted. Look at the white with green and you'll see that your blade connector is inserted in the same location, as in a fused constant source. That is what a add-a-fuse would do if inserted in a constant source also. (There is only one fuse in the engine room fuse/relay box that is an ignition sourced, but it's tied to the circuit that does the leak test after shutdown, which in turn would make any wire tapped to it hot/on for the time the test runs)

    so what am I risking by not putting an add-a-fuse in there? So far everything has worked other then me leaving my fogs on one day and my roommate telling me that after I had been home for 2 hours.

    Just an easier tap than the wedge to the HORN relay slot...that's all and the fact that the circuit is always ON. (battery drain)

    Yeah horn relay would not be ideal given that you can leave foglights on with the key out.

    Tapped in or add a fuse doesnt do a damn difference though.

    Absolutely none.

    I can pretty much guarantee though you will end up forgetting the fogs at the worst time. Also if you wanted to do it this way, there would be no need to tap into another relay. You could simply grab the constant hot from the same socket as the fog light relay, run two wires out of one spade from the main constant hot.

    So I have run into my first issue already when I first did this mod my horn worked now my horn does not work but my fog lights still work what in your guises opinion would be the best way to wire this up I am not very good with electric stuff so any step-by-step process would be great

    Swap the wire tap of the horn relay for an add-a-fuse and place in the EFI No.2 fuse.

    You'll be able to have the fogs ON after ignition without any other lights needing to be turned ON.
    Just remember that if you leave the fog switch ON, the fog lamps will turn on when the vehicle does the Leak Detection Pump test.(like 5 hours later for 2 mins)
