Jeff, not sure if yours is the same as mine. I know it as a Pilothouse sedan. After my wires come down the wire chase in the front starboard corner of the pilot house they come back along the window and pop out through a cut out under the helm. Sorry about the pic being sideways. No idea why that is happening. When I changed the radar and gps antenna out I was able to use a wire snake to get the wires down to the front corner. From there I was able to back the slack out of the radio antenna from under the helm out the front corner access panel. From there I taped the new radar and gps wire to the radio antenna wire and fed them through and under the helm. Hope this makes sense I know I did not explain it to well.
