Q:Is it possible for a wire to arc with a nail? The u-nail that hangs the wire to a wooden support beam looks like it was hammered in too far and may have cut through the insulation around the wire. Is this a fire hazard or can I leave it as is?

If you're talking about Romex cable, and a staple of the type commonly used to anchor it, some shock or fire hazard might exist. It's hard to tell without seeing the case. The cable consists of two or three insulated wires and a bare copper ground covered by an outer plastic jacket. If only the outer jacket of the cable is crushed or pinched, the danger is minimal. If the inner insulation of the wire is compromised there might be trouble. If you think this is so, show it to a 'Pro'. No-one can responsibly advise you without 'eyeballing` the situation.

Q:its an older boat without fuse box, if you go to the manual on the website it gives you the wire layout. I know the radio works but a friend of mine disconnected the wires to try to put a switch in and never reconnected them. I don't know what to do with the ground wire or the red wire. Any suggestions?

the ground wire black is connected to -ve of battery the red wire is connected to ignition wire so when you turn on the keys the radio starts the yellow wire is connected to +ve of battery, but radio will not switch on till red is connected. good luck

Q:need color of sig wire on maf and witch wire is sig on 02 sensore

Yes we do need car description.O2 sensors black wires are normally for the heating element.It should be one of the white wires.The wire will read 0.2 volts with a cold engine and fluctuate between 0.1-0.9 volts at normal operating temp,so look for the wire which has these voltage reading.The maf signal wire will have less than 5 volts on it.Generally it will show 0.60-0.80 volts at idle and increase to between 1.50-2.20 volts at a 2500-3500 rpm level.Be aware that a maf sensors heated wire can become dirty causing it to read and function incorrectly,so it may just need to be cleaned rather than bein replaced

Q:And i am unsure on how to wire the speakers. Do i just splice the wires from the speakers to the corresponding wires on the harness. P.S. It is not actually in a boat, it will be connected to a 12v battery.

U JUST RUN THE HOT(RED) WIRE TO THE BATTERY. U ALSO MIGHT HAVE TO HOOK UP THE MEMORY WIRE(YELLOW WIRE) AND THE REMOTE ( SOLID BLUE) WIRE TO THE POSITIVE TERMINAL OF THE BATTERY AS WELL BEACAUSE SOME RADIOS WONT TURN ON WITHOUT THESE WIRES COONECTED. THE WHITE AND GREY WIRES ARE THE FRONT AND THE GREEN AND PURPLE ARE THE BACK SPEAKERS. YOU SHOULD GET THE WIRING HARNESS FOR THE WIRING IF ITS GOING IN A CAR LIKE A JEEP THEN ALL U GOTTA DO IS MATCH THE COLORS UP ITS EASY . BUT STRAIGHT TO A BATTERY DO IT THAT WAY JUST MAKE SURE U HAVE A GOOD GROUND.

Q:My starter I replaced has 3 wires, two red and one black. Where does each wire go? Pictures would be very helpful if possible

The First red wire goes to the solenoid on the fender well right by the battery. the second red wire goes from the solenoid to the starter on the one main post there. the black wire goes from the engine block to the battery on the negative side. All connections must be tight but not not crushing on the battery
