I need a wiring schematic for a 1985 SRV300 sedan bridge. Does anyone know where ican get it. Or download it. The searay site does not have that model listed.

Im replacing all the wires due to salt corrosion. And i cannot figure out where some of them go. Im using all aircraft grade sealed connectors and wires.
 
There may not be one, at all. Back then, you were likely to find a color code list - but not an actual schematic. However, go back to SR' site and looka few years newer/older than your boat and you might find your model, just in a different year. HOWEVER, the wiring is standard. Meaning, if you find a color code for another boat, it will be the same for yours.

It's not uncommon to have to figure this out without the help of a schematic, though.
