Boat wiring
 

I have a semi decent grasp on the concept. I have completely wired a couple offroad buggys and trucks before. Since I am moving my dash, the wiring will need work. Thinking it will be easier and cleaner just to start over.

The trim system still has me perplexed. after looking at various schematics, I believe the trim sender wire is in the main merc loom and the trim limit is included in the merc trim harness correct?

Anyways, what am I forgetting or do not have sized correctly?


Bow: Bow light
Cabin: cabin light
Dash Top: compass
Dash front : temp/volt/oil/fuel/tach/speedo/trim/hour/ignition/trailer trim/GPS
Console Top:
Main switch panel horn/ nav lights/blower/bilge pump/bilge lights/courtesy lights/ cabin light/ insturment lights/
Trim switch panel port tab/drive/stbd tab
Stereo
neutral switch
Console starboard: courtesy light/ kill teather
Console port: courtesy light
Console interior: Amp/ buzzer/ fuse block/neg bus bar
Cockpit front: Speakers x2
Midship: horn
Cockpit back: speakers X2
Bulkhead: courtesy light / bilge pump/ fuel sender/ bilge light/ blower/ courtesy light/subwoofers X2
Transom: tab port/ stern light/ tab stbd / trim pump/trim sender&limit

Runs needed:

merc harness (ignition/gauge senders)
bow light (16/2 duplex)
horn (16/2 duplex)
merc trim harness
port tab (14/2 duplex)
stbd tab (14/2 dublex)
fuel sender (16/2 duplex)
console/dash /main power/ground (12/2 duplex)
Stereo/amp (10/2 duplex)
Blower (14 ga.)
bilge pump (14 ga.)
Stern light (16ga)
bilge light (16 ga.)
Courtesy lights (18/2 duplex)
speakers (front/rear/subs)

Make sure you fuse everything. I've seen some pretty clean installs with this:

Also, not sure what size your amps are but number 10 is likely too small.

Use the correct colored wires for marine wiring as well.

Is there a color code somewhere for reference ?

get your wire and connectors here

Make sure to use heat shrink terminals and splices to seal

I only saw red, black and green marine grade pre tinned wire at the delcity .net site . Not enough selection to keep things straight(color wise). ? or did I miss something

If delcity doesn't have the colors you want pacer does

you probably already know this but only use good quality tinned wire, do not solder anything and heat shrink everything.
