Re: "72"Penn Yann rewire
Think of it this way. There are 3 main harnesses in a boat. The first is the engine harness. That is the wiring on the engines and it terminates with a connector mounted on the engine<br /><br />The second harness is what I will cal the cockpit harness. It runs from the connector on the engine to a connector under the dash. It carries your ignition wires, your senders, trim control, etc. <br /><br />The last major harness is the under dash wiring - the gauages, swicthes, etc. which plugs into the cockpit harness.<br /><br />Everything else is home run type wiring for the most part - that is wires running from point A to point B as needed.<br /><br />You should look into buying new matched cockpit and engine harnesses. Contact the mfg and see if they are available or you can often times find new harnesses on eBay - the issue is the connector between at the engines. Ideall you want to match what is already there OR replace the engine harnesses and connectors at the same time.<br /><br />If you take this approach you will save your self a lot of time and decrease the likliehood of making mistakes.<br /><br />When I rewired my Formula with twin 350s I used new Seray cockpit and engine harnesses. I then wired the new guages my self using all brand new guages and switches - no sense doing all this work and using old stuff. I made my own connectors for the dash/cockpit interface. You could also skip that connector and wire directlyto the cockpit harness if you wanted.<br /><br />You will need to purchase the correct tools - you need a high quality ratcheting crimper and a good automatic wire stripper and a good multi-meter and the very least.<br /><br />I can't emphasis enough that you need to understand the ABYC codes and fundamental good wiring practices for marine = military/space quality<br /><br />Only use Marine grade wire and connectors like that made by Ancor Marine.
