(T) Battery to interior for hands free.

Hi
I just bought a Sony Ericsson HCB-300 and i need to connect it to the battery from the cabin. does anyone know where i can take the cable to pass it through to the engine bay? I've had a good look but can't see anywhere obvious.
Also would anyone know how to connect a cable to the ignition?
I know I should get it done professionally, but funds etc don't really allow. And i'm normally quite good with these things...
Cheers!

Loads of threads on taking wiring through bulkhead......clue.....behind battery area on bulkhead behind the insulation material

yeah if its a punto theres a gromit down behind the battery in that region behind the insulation material, theres always gromits, follow the wires that look asif they go into the cabin and youll find it.

cheers i'll have a go tomorrow, it's going to be complicated, but I like a challenge!
would anyone have a clue where to put the ignition lead part of it? it just says connect to the ignition of the car

thanks so much for the posts! cheers

by the way it's a W reg sporting mk2!

Any ignition live.....if your unsure use the orange thin wire at the ignition switch....I assume your is the later punto(188)?

i don't know what you mean by later punto 188? It's a mk2 from 2000, so one of the first mk2's. I'll go and have a dig for an orange wire!
Cheers

Thats right mate on the ignition switch is 2 multiplugs,one of them has a orange wire thinner than the rest.

Or failing that, in the passenger footwell, there is a large 2" (?) diameter grommit, perfect position for battery. Just pull down the carpet and voila.
