Just went through this this weekend. Took the 480 out of the nose, the GPS antenna was under the console. Had to cut the connector off the extension cable, would not pull through the conduit (must have been installed befor the top cap was installed). Had to cut the connector off the transducer for the LCX 15 in the hull, same reason when I removed the LCX 15 from the console. . Before I pulled the old wires out, I attached safety wire (bailing wire) to the wire end and pulled it through. That way, I had a wire to use to tape the HB 1197 and 898 wiring to to pull them whichever direction I needed. Basically, I had to pull the SI transducer, the quad beam (no 2 tranducer for the 1197) and the GPS antenna wire from the back to the console. pulled a power wire and the interlink wire from the nose to the console. I like to power all my electronics from one switch to the battery rather than having to turn on the accessory switch. Better that way when I dont need to run the live well stuff.Still have to connect the interlink and weather sense in, but that will be a snap now.LOTS of work, I cant imagine ever getting a LOwrance system installed easily with thier big connectors.Milton
