Need help plz: Issues after installing Digi-Tails

[72Z/28]

I gave up.

I have checked the damn wiring on those side markers, and they are correctly wired.

I do not know why when I put those stupid LED side markers, voltage gets introduced into the blinker wire.

When both side markers removed, the voltage at each blinker wire is zero, and both dash indicators disappear.

When I put driver side LED side marker, voltage of 5.9V gets introduced into blinker wire, zero voltage at passenger side blinker wire, and driver side dash indicator gets lit.

The same when I put Passenger side LED marker. Voltage of 5.9 at passenger blinker wire, and passenger side dash indicator gets lit.


I just can’t figure out what else to check for.
