Hey,

Ok, got the trailer marker lights working now but now no trailer brakes. I have an after market brake controller plugged into the factory harness under dash and as been working for years. trailer brakes will not work on either of my trailers. So I looked up the fuse and it's a F105 put never seen that type of fuse, it's pink, larger the normal and it has a little cover on it. So do I replace the whole thing or take the cover off and replace what's in it. I know this may sound stupid but have no idea.

Thanks

 

ok finally found out its a FUSE CARTRIDGE and I need to replace the whole thing.

Thanks anyway.
