I have a 2008 Puma and ran the transducer cable last weekend for a SI unit. I pulled the driver-side chrome vent and used a fishtape to run the wire from under the dash to there. Went pretty easy to tell you the truth, but I had to get my daughter to reach in through the hole for the vent to grab the tape. My arm couldnt make the turn required. For power, I caught a wire under my dash that was powering my other depthfinder. No problems so far.
