Buy a gland fitting, you will need to use round cable so the gland will grip it. Fitted one on my front roof for a light bar 14 yrs ago, still perfect.
I got hold of some stuffing glands.
I drilled a hole at the rear, but it has 2 skins of body work with about a 10mm gap between them - the thread on the gland doesn't reach so i can't secure it.
Can you get stuffing glands with long threads? I had a look but can't seem to find any. Is there any other similar solutions?
Thanks,
Foz

No u can't get longer threads, so cut a larger hole in the inner skin to give access to the glands locking nut/ring, although not so easy of neat now as if that had been done when there was only the pilot hole.
That's a shame.
That was my first thought, but there is actually a third skin on the inside - it has a hole about an inch big but my new hole isn't directly in front of this hole, so I can't get a drill in there. Might have to just spend ages filing it down.
how long would the thread need to be? i have used glands with up to 25mm of thread so they are available (RS components i think would do them, as would marine electrical suppliers), although the gap behind the outer skin may just bow inwards and leak when it was tightend as there would be no ''crush tube'' as such. use a ''carbide bur'' in a power drill or die grinder rather than filing it will be much easier and faster.
I did have a look on their website but I can't find a M12 gland with a long thread, anything over 10mm. You've just introduced me to a "Carbide bur" though - so i'll buy one of those, that should sort it. Thank you!
always try and use the largest diamiter one you can fit in the hole as it helps to keep your radius correct, they work well in any power drill but they are EXCELENT in an air or electric die grinder, i cannot reccomend a die grinder enough, one of thoes tools you think you dont need untill you have one then its used all the time, even a cheap cheap one will turn horrible jobs into hardly jobs at all. with a bit of practice you can preform surgery with them.

when ever you drill a hole, make sure you drill one on the opposite side, one to let the water out, if water gets in through the other one
