fitting a apache 13000 winch

hi all. im new to owning a 4x4 and have also recently purchesed a apache 13000 winch to fit my defender 110 td5.
can any one whos got/fitted one give me any advice: the supplied leads seem a bit short which i can extend but do i just go directly back to the battery or run the neg to the chassis? ( will it affect v drop etc if i do that) also should i be fitting a second battery.
sorry for whats probably a daft question but going from a boy racer to a 4x4 is a learning curve.
thanks

Fitted a winch to my 110 TD5 a while back. Not the same winch but the principles will be the same.

Here's a link to the thread I posted about it.

Hope you find this helpful.

thanks, helpful seeing how someone else has done it. didnt even accur to me if the grill etc would be in the way.
so much for a quick bolt on job.

I;ve got the same winch as you,

But the battery on a d1 is much closer, I suggest getting some extra earthing cable and running it along the side of the chassis

had a feeling id have to extend them. should i extend them both back to battery terminals or can i attach the neg onto the chassis and just extend the pos. ?

just extend the pos...thats all i did bolted eath to the chassis

To make extension easier use an isolator switch with also stops any power drain
