Hey guys I'm new here. I've learned a lot from this forum over the years so I figured I'd join. I bought a 1993 gmc sierra and an old mm1 fisher. The electronics I bought separately because the price was right. I got the mounts and all the harness for 250 bucks. I just installed everything minus the plow today and I've got both low beams on the truck. On high beam, my lg beam lights up but my passenger side low and high beams come on at a glow at best, while on high beam!.........disclaimer, the harnesses came off a 90 gmc w/t with single sealed beams, I have the poly capsules on mine. I modified the harness to save a few hundred bucks. I MAY have goofed up, BUT, I've made alit of harnesses and I'm pretty savvy with that stuff. I figured I'd ask if anyone else has had this issue. I tried to play with the configuration plug(4port module) and all I did was go from both lows on low to only LH low on low. any insight help or experience is much appreciated!!
