Anybody have any ideas?? this thing was completely rigged when i got it but trying to get it back right and pulling my hair out!! any help would be appreciated!! thanks guys!!

Alot depends on where the wires are that are not connected, i.e. at the switch panel, or somewhere in the stern / bilge area. Also, do you have an automatic bilge pump, or a pump and external float switch.
Anyway, some standard colors:
Brown usually goes to the bilge pump.
White is also found on the bilge pump but connect to ground
Red is usually +12 volts
Black.is usually ground

Let us know a little more about switch panel, new or old. if old can you trace the wires from the switches

ok, its in the stern/bilge area, only thing i know about the bilge is it doesnt come on unless you hit the switch, the brown and the white go into the harness, then the red and black go over to the blower but have crimped eye fittings on them, no other wire i see for the sending unit. this has a mercathode overtop the breaker but only thing that was ever hooked to it was one black wire that goes into the harness, im sure they must have bypassed it but not sure why, i was ripped on this boat, ive replaced floor, stringers, motor mount boxes, bellows, motor, and its only been on the water maybe 3-4 times.

Yes, brown to bilge
The red & black wires, are they a heavier gauge than the others? Those could feed the dash.
Blower is usually yellow but who knows in 1990. It may be white.
Fuel sender has been pink for quite a while.

ok brn and wht to the bilge, the red and blk wires are a smaller gauge, probably 18g, but theyconnect to a yellow and forget the other color heavier gauge that connects to blower, but only about 3 feet long so def not long enough to reach dash. i must be missing the wire for the fuel sending unit, like i said this thing has been so cobbled up who knows what exactly has been bypassed but i guess little by little i will get it! lol. thanks guys, ill keep looking
