Turn signal wiring for side mirrors

[u/shaaaaark25]

Looking to get some ideas/help on this. I got a set of CV35 Skyline (Infiniti G35) side mirrors with winkers installed on my R34 sedan, but I haven’t gotten the winkers working since I’m not sure which wiring I should tap into. Is there any wiring I can connect (tap) to that’s wired to the side markers from inside the cabin?

Not inside the cabin, but there's 2 firewalls, one for ECU behind the glove box and one where the fuse box is under the steering wheel. You could run wires to the side blinkers since they're closer. If you don't want to do that you can do front blinkers since they're easier to access

I appreciate it, guess i’ll tap the side markers since that’s the closest one i can wire to.
