Best to restore harness to factory OEM condition 1st before trying to troubleshoot signals. Put harness connectors back on harness: https://www.corsa-technic.com/item.p...category_id=49

Then use matching connector on winker lights: https://www.corsa-technic.com/item.p...category_id=49

This will let you unplug all rear-lights to test front-lights only. And once those are working, unplug front-lights to test rear-lights.

Also need proper 2-pin flasher relay. Extremely likely that 3-pin relay is not wired up properly because socket for factory 2-pin relay can't accommodate 3rd pin. https://www.amazon.com/Yibid-Adjusta.../dp/B078L3CGH5

Right now, you have no idea if there's wiring problem, or issue with how relay is connected or problem with winkers themselves. By disconnecting and reconnecting one component at time, you can narrow down issues. Best troubleshooting step is to plug in factory winkers 1st to verify everything works as designed from factory, then it's simple matter to unplug one light at time and plug in aftermarket light (with matching plug-n-play connector attached).

Here's write-up I did for Hondas, same procedure, but easier with Kawi because no diodes needed.
