I replaced my already round headlights with some jk ones. Therefore I had to splice the new connectors. Got all the wires connected correctly but my daggum low beams wont work. Never had this problem with my old ones. Would my switch randomly break by replacing the harnesses? All my fuses are good. Is there a larger fuse under the hood I could check for? My brights dont seem to bright either but then again its daylight. Ugh what did I break now?

 

When I put a new putco harness in my 98 I had problems. My highs and lows would be on at the same time. I removed my fog light relay/fuse (can't remember) and that fixed it! I wasn't running any fogs. Hope this helps

 

Get a test light and see if you have power at the low beam wire still, preferably before the splice.

Got it to work. Now theyre just angled all crazy.
