[QUOTE="Bounce, post: 1021643, member: 257"] +1 on this. If any electrical change has a larger draw than the OEM part it's replacing then you MUST run a separate circuit with larger gauge wiring and fuse to the new item. You may opt to then activate it using the OEM circuit as the energizing side of a relay. Step #1 is that, if you don't understand the basics of a relay then get someone to help you. Slashing and smashing your OEM harness is not something to do without a very clear understanding of the basics. I mention this simply because of your comment That's one of those "basics" I was talking about. It [U]can[/U] and it very like [U]will[/U] (eventually). if there's a load on that circuit that it higher than the 10 amps that the original circuit was rated for (including the wiring), the fuse will no longer be the first thing to fail. The light gauge wiring now becomes a "fusable link" with a lower load rating than the fuse. OEMs don't build in much head room in harnesses because that costs money. [/QUOTE]
