Re: battery connection???
For starters the thick red cable will be your positive and the thick black will be your negative.
With that in mind place your battery back in its holder. Now - just check the length of the remaining cables and place them on the appropriate post.
Now - this is NOT a professioal way to do it but it is a start. Best would be to run a continuity test through the remaining small wires and track from there.
Do you have an MBSS ???
Here are the standard wire colors used in the boating industry since the late 70s. When re-powering a boat with a newer motor this is a handy reference. Most boats use these standards but always double check in case changes have been made!

Some more standard wire colors used on many inboard boats, always double check though, as some vary or may have been changed along the way!
Some standard colors for boats since 1980 are as follows:
? heavy red 10 guage (main battery)
? heavy black (main ground)
? purple (ignition)
? yellow (starter solonoid)
? grey (tachometer)
? brown (temperature)
? blue (oil pressure)
? brown with stripe (alarm)
Accesories
? pink (fuel sending unit)
? yellow (blower)
? brown (bilge pump)
? grey (navigation lights)
? heavy green (bonding wire)
? red (misc electrical add-ons , vhf , depth finder, stereo, radar, power supplies)
