my reverse lights are coming on in reverse and also drive. I tried changing the bulbs and a new reverse light switch and still the same thing. I’ve looked for grounds but if it was a ground the lights wouldn’t light at all correct? Idk what’s going on any help on knowing where grounds are or adjustments which ever I would greatly appreciate it. Can email my at kuntryboy1029@yahoo.com or my cell 2523403140

Also when I screwed the new switch in I went rhrough my gears and they still came on in drive as well but when I went to he back to park I could go past neutral I actually had to back the switch out about 2 turns cuz it was hitting. Then it went to park but I measured both switches they’re exactly the same length

I thought shift linkage as well but all my gears line up and shifts fine no slip in shifter. I put in a new switch and it does the same thing. I’m not to experimented on electrical but what should I look for if the pins are shorted out like u said

Also how should I check to see if shift linkage is adjusted right just something I can try

What’s the best way to tell if it’s shorted out at the plug never had to do this before
