Relay cable set PURELUX Pro Series 12V, HD DTP

Hello! Yes, it is absolutely possible to install these lights with a separate switch in the passenger compartment, but you need to be careful with your choice of wiring harness because you are connecting three very powerful lights. Here is the technical breakdown and my recommendation for a safe installation. 1. The Problem with the "2-Output" Harness You mentioned the Purelux DTP 2-output harness. The Connection Issue: You have 3 lights (2x Panther 7 + 1x Panther C540) but the harness only has 2 plugs. You would need a splitter, which adds resistance. The Power Issue (Crucial): 2x Panther 7 = approx. 244W (in PowerBoost mode). 1x Panther C540 = approx. 200W (in PowerBoost mode). Total Load: ~444 Watts. The 2-output harness is rated for roughly 480W total, but usually only 240W per connector. If you split one connector to power two Panther 7s, you might overload that specific wire/fuse. 2. The Professional Solution (Recommended) Instead of the 2-output harness, I strongly recommend you order the 3-Output Version of the same harness. Product: Purelux Pro Series Relay Wiring Harness, 12V, DTP (3 outputs). Why: It has 3 separate DTP plugs (one for each light), so no splitters are needed. It has a massive 80A Relay and 60A Fuse, which can handle up to 720W. This gives your 444W setup plenty of safety margin. 3. How to Wire the "Separate Switch" Since you do not want to trigger the lights from the high beam (stalk), you will wire the "Trigger" cable manually. Install the Harness: Connect the thick Red (+) and Black (-) to the battery. Plug in your 3 lights. The Trigger Wire: Locate the thin signal wire coming from the relay (usually Blue or White). The Switch: Run a wire from your Battery Positive (+) (or an ignition-live fuse) -> Through your Switch inside the cabin -> Connect to the Trigger Wire. Result: When you flip your cabin switch, it sends 12V to the relay, and the relay turns on all 3 lights directly from the battery. Summary: Buy the 3-output DTP harness to ensure you have enough power and plugs. Then simply connect the trigger wire to a +12V switch instead of your high beam signal.
