Engine Mechanical / Electrical / Need Guidance on Rewiring my Boat
« on: January 11, 2022, 04:12:28 PM »
Hey guys,
Done some searching and come up with some general ideas but would like to have some more info before digging into this. I am aways off from needing to wire as I need to put the motor together and drop it in. I am mostly ready for that as machine work is done and I believe I have everything I need aside from drive to get it buttoned up. I've attached the diagram from here as well as a color coding diagram I found online as well.
The boat is pretty simple. 455 olds, single battery, HEI, 3 wire alternator and gauges basically. I found the wiring diagram hosted here for a 3 wire with HEI setup that I plan on following. Was thinking of adding a fuse block but not sure its needed I plan on daisy chaining the gauge power and gauge lighting. I could fuse each circuit but daisy chained I'd assume if a gauge failed it wouldn't pop the fuse for the whole daisy chain, and the same for the gauge lighting. That leaves the bilge and electric fuel pump. The electric fuel pump I was planning on adding a fuse inline when I install the relay and I guess I could do the same with the bilge.
I would like to do away with the terminal block and run a deutsch connector for the harness at the rear of the boat. Following the diagram I found here it looks like I will need 3 runs of 10AWG wire to the front of the boat. This will go through the main connector and Deutsch doesn't appear to offer a connector that has 3 10AWG in any of their lines. Has anyone with deutsch know if maybe I'm missing something?
Other questions:
I'm sure I'm missing stuff here guys but this should be an easy start. Any help is appreciated.

Other questions:
- Do I need 3 10AWG to the front of the boat? (Constant hot, ground, starter signal from ignition)
- Where should I source appropriate wire?
- Where can I mount the aux solenoid? straight to the stringer?
- Is a fuse panel necessary? If so do I mount one under the dash or back by the battery?
- If I put a fuse panel in will it be run of the ignition switch or constant power?
- Instead of running the solenoid as show in the diagram can I run battery to one side and then instead of the white 10AWG wire to the S lug on the starter, run a large battery cable to the main starter lug with a short jumper to the S post on the starter? this way the only time the starter is hot is when the key is in the cranking position?
