Any tips ?

Can anyone tell me where I can get decent 12v power supply in the engine bay to run a winch from

Yes, it's called a battery. You'll need to run a single cable to the battery. Can't tell properly from your avatar but you have a 110 Defender ?. Not a difficult job, down the LHS chassis rail to the battery box.

I also can’t see any easy way of getting a UHF cable through to my radio through the fire wall without a dash removal .

It's been done. What sort of VHF and where is it mounted ? It can be an absolute bastard working under any dash, but you can guarantee whatever you're attempting has been done before ( with varying levels of stress, frustration and swearing).

Take a deep breath, (I sense a fair degree of frustration here) and give us a bit more info and we will help you to work it out.

I have been thinking of running a + and – terminal to the engine bay so it makes fitting accessories easier.
As for the UHF cable I’m wanting to run a cable with a SMA connector for a hand held Uniden UH076SX-NB . So Il be running the cable to the center console.


Il also be using this antenna

I ran my UHF cable from the bullbar, down the left hand chassis rail into the battery box and up beside the passenger seat under the sound proofing, silicone all holes around cable and it's worked well now for about 3years

I've got power to my winch doing what's said, (down the rail into the side of the box), and at present, my ariel just going through the door untill I can get motivated to run it along with the winch cables.
When I've hooked in the second battery, I'll also have power directly to the UHF and and other gadgets through the main battery box too.
Not wishing to hijack your thread Doc, but i have similar enquiries.
My problem at present, is what's the best way to set up for the extra power from the box. Pics etc on what others have done might be handy to see as well.
So whoever is the ideas man

looking into the engine bay from the grill; on the fire wall left hand side up top there is some rubber grommets behind the heater taps. Using a feed wire you can track a UHF cable down to under the dash. It comes out a fair way up but is in line with the speaker from memory. From there it's as far as you want to take it.
If you want to run a centre roof console; it's easy to run the cable up the A pillar and across the front of the hood lining. Thee is no need to detach the hood lining.

A winch draws heaps of current under load, a direct circuit with the battery is required otherwise you will cook something. Run at least the same size cable as the winch, or even up size it a bit assist in reducing voltage drop because the Defender battery is a bit further away than normal.

I dont run a on/off circuit breaker switch, many do. Usually it is fitted to the outside of the the a battery box or somewhere convenient to use. I run a set and forget 200amp fuse mounted in the battery box which I got from Jaycar.

what about running the winch + to the starter motor connection, i assume the puma starter motor has a big cabke running back tot he battery

That's what mine does on a TD5

Surely then a fuse or circuit breaker between the starter and the winch?
