orange wire?

[jrisapirate]

So just replaced the original glass fuse block and original switches on my '87 20 fisherman(have to correct myself because I always thought it was an '89) traced all the wires and for the most part and they are still in decent shape. Especially for not being tinned. Close to 30 years on basic copper wire not bad I'd say. But I haven't been able to figure out the orange wire from the harness, only guess is an accessory?
And while I'm on it there are heavy battery cables that run from the port side locker to the bow. The port/plug they are connected to is un legible and not a plug I'm familiar with(i'll try to get a pic up) any ideas? Guessing it has to be an old dock charging plug? Cables are way to heavy to be any kind of accy.

Trolling motor plug?

I could never figure out the orange wire either.

That makes sense for the heavy gauge wire.

The orange has to be for an accessory.

The original pink wire from the fuel sending unit looked kinda orange on mine...
where does the other end go?

[jrisapirate]

It is loose at both ends of each harness(the aft and under the console). I dont think there is a seperate ground for it either because each black wire was accounted for when reconnecting the other colors
1.yellow - pump
2. black w/red - float
3. brown - bilge
4. blue - lights
5-6. grey and grey w/blue - nav and anchor
unless the nav and anchor share a neg, and the 6th neg wire from harness is for orange wire?
Is each neg designated to its own color?

Could it be for additional bus bars?

[phatdaddy]

As it is a center console, did it have a built in live well?

[SkunkBoat]

well, there must have been a feed for the horn, wiper? At this point its all up to you

[jrisapirate]

Yes CC. Yellow went to the livewell pump. Horn uses its own wires to the push button, but that could of been a possibilty for original wiring.

Isn't there a wiring schematic in the links section?
