I have a late model A4 and have decided it's time to overhaul the electric. Most of the wiring from the engine appears to be original, all of which leads to a terminal block. The block is suspended above the engine, hanging from what appears to be at least 10 feet of wires - all correct color coding and neatly wrapped in a loop that is tacked to the engine compartment ceiling. That loop of excess wires terminates in a trailer type plug that leads to the gauge panel. It's quite a mess and seems like a very likely, eventual point of failure that will be difficult to diagnose if there is a problem.
I plan to do the following and would appreciate words of advice. There is nothing complicated about this, but I'm just somewhat experienced in re-wiring systems on this boat.
1) Remove the trailer plug and permanently mount the terminal block to the engine compartment wall. I've added a couple photos, one of the terminal block, the other of the plug. I don't have a good picture of the wire loop, but it appears to be pristine wire, almost still looped the way it was whenever it was installed.
2) Use the existing excess wire that is tacked to the ceiling to wire from engine components to the block.
3) Use existing excess wire to complete connections directly from the terminal block to the gauges.
4) Replace all the gauges and potentially the ignition & fan switches.
5) Clean all connections.
