So this whole lighting thing has been a disaster for me I knew nothing about wiring until the great people in the community have educated me a little bit. This one has me stumped. I bought a brand new non-rs to rs halo always on harness from gen 5 diy. I put in that lights and try the high beams, first time only drivers side worked. So I pulled fuse and tried again. Then only the passenger side works. Now knowing they both work I'm assuming it's the harness. If anyone can help me it would be greatly appreciated, sorry for all the questions on this thread just trying to get it right. Couldn't find too much updated info on this topic. Thanks!
