New Altima owner here. I have a 2023 Altima SR, does anyone have a wire diagram for the headlights? I bought an LED light strip, that's I've put at the edge of the hood and I'm wanting to splice that into the wire that control the auto on/off part of the headlights so the stripe turn on with the headlights at night.

Eventually going to get a light up nissan emblem for the front bumper also, I'm also wanting to splice that into the auto on/off wire to the headlights

I can get you the info tomorrow at the shop, but are your OE headlights halogen or LED (different wiring), and do you want the strip to come on with the Parks, or the Low Beams?

I have LEDs and with the lowbl beams

I'll get you connector layouts and wire colors tomorrow. You should be able to just tap one of the Low Beam power wires to drive a relay. The IPDM on your ride has "Smart FETs" instead of fuses, so I don't recommend driving additional loads directly off the headlight supplies. One 40A "Bosch Box" relay from the parts store will more than suffice to drive both the strip and emblem.

Here you go. Connector views are harness side (the side where the wires enter). You want to tap one of the LIGHT LBEAM wires and run it to one side of the relay coil (85 or 86 on a Bosch Box), the other side of the coil goes to ground. Wire terminal 30 (common) to 12V battery through a suitable inline fuse. Terminal 87 (N.O.) goes to your lights+, lights- goes to ground. Terminal 87a (if present) is unused.

Thank you! Another question probably a dumb one, how to I wire all this in so where I don't throw a can-bus error code on the module. Dealer ship said that will void my warranty to whatever is associated with the error code. I'm more into the mechanical upgrade said if things I've never dealt with electrical before

You won't get any errors from t-tapping a low beam wire, the relay coil will just look like an extra 175 milliamp load to the IPDM. It won't affect the internal diagnostics for the headlamp at all. No worries on that score.
