Okay, so I want to change the side marker lights (small yellow lights in picture) to side marker and indicator - see the link New unit has 3 wires. I'm guessing ground, marker and indicator.Question - can I just tap in to an indicator and marker feeds to feed these new units or do I need relays and other stuff?Link to new marker/indicator https://www.beaconsandlightbars.co.uk/product/fristom-ft-080-12-24v-led-cat-5-amber-marker-with-indicator-surface-mount-pn-ft-080-led-22958
Unless you are running an assload of indicator lights you should be fine splicing into existing wiring to tap into it. Just make sure the amount of lights you run are under the amperage load of the wires and fuse.Also if you use scotchlocks i will personally find you and hurt you.
Yeah
