    my clearance lights aren’t working after installing new ones(old worked fine). Couldn’t figure it out and brought multimeter next day. Connector at switch is getting power but none of the 5 plugs for the lights are getting power. There’s maybe a foot and a half tops of yellow/white wire coming out of harness to each plug, idk what I could have done other than tug on one when unhooking old lights but I wouldn’t have guess it would be hard enough to break a wire inside harness. I’m not sure what I do wrong

    Took me 10 minutes going through post to figure out you tagged on anothers old post. Those are great for research but sometimes it is best to start your own. Begin with year make and model. Last 6 of the vin?
    Many newer models use control modules. On a 388 here the chassis control module was in the left frame rail behind the transmission. Fuses for it were in a box in front of the left firewall. They do some funny things. Fuse for the RR turn signal also runs the LF and vise versa. I thank all the lights on the truck run through it.
    Did you replace standard lights with LEDS? A module might not like that.
