78 Troopy: Where to Connect 12V Dash Accessory?

[SimonW]

I am in the process of mounting a Nokia hands free phone kit into the dash in my 78 series troopy.

Can anyone advise me of where is the best place in the Troopy to connect the 12V power for the phone kit?

It needs to connect to ground, which I assume the best place to connect to would be the grounding points near the fuse box.

I'd like to know the best places to connect the 12V to power the phone kit, as well as the IGNS (ignition sense) which I think connects to the accessory power.

I'd like to connect these back to the fuse box if possible, rather than splicing into existing power lines for something like the stereo system.

Any advice or tips most appreciated.

Thanks.
