Interior light wiring

I want to put a second interior light in the back of my 90 so i can see tools etc when it gets dark, so where is the best place to wire it to ??
would it be ok to wire it to the exsiting light in the front so they come on together??

The front i terior ligjt for power. Yu could hace them switvhed together, or the rear one switched by the rear door. Your choice. Wiring em up would be slightly different tho.

the light has its own switch on it i just need to get power to it, does that help daft ?

Run a purple wire from the power side (purple) on the front switch thru to yo new switch. The switch yu have is normally an overide switch. Run an earth (black wire) from the switch to ground. If yu have another contact - yu run an earth via a door switch, so it comes on when you open the door. Tiz a simple circuit, but i cant draw yu one at the mo, ciz i am on my i-phone.

power -\- ground
-\- ground(door switch)
best i can do - soz

Be aware - purple is Always live- so take care!

while i am picking your brains what would be the most likly cause for it to keep blowing the 20amp fuse it the one for the clock internal light and horn, it has only decided to do this today, as soon as i put a new fuse in it sparks and blows????????

dead short

No idea. A fuse blows because too much current is being drawn thru it. Have yu touched the lectrics yesterday? If not, possibly a wire has worn thru and is shorting to ground. Try tracing the wire from the fuse and/or isolating sections, to try and ascertain which bit is causing the problem. Sometimes replacing the fuse with a lightbulb helps, cos it wont blow, but shows when the circuit is still faulty.
