installing this LED anchor light but for some reason the front LED is not coming on when in anchor mode only. It’s 3 wires so it seems plug and play. Anchor light on dash comes on but still only lights the rear running light. Any thoughts? Fuse somewhere?

If you're getting voltage then I would check polarity. A lot of LED s will only work wired in one direction.

Well, voltage may be my issue. On the running anchor light wire I get a constant 12.34 volts. On the anchor wire I get nothing. So I’m wondering if this is an EIM issue similar to what I had before on some of the 12 volt outlets.

Is the wiring setup so that anchor switch turns on both, and Nav switch turns on just the front, or vice versa? If you have the rear nav white light on your bow anchor locker, you don’t need (or want?) the mast anchor light on for the rear when navigating.
