I need to run a pair of wires from engine to cabin. I can't really find any place to run them through and I can't imagine whene I could get them from inside the cabin since it's so full up. Is there any image with instructions that clearly indicate this track?

I also need to connect the wire on the 12v ignition.
1) Should I disconnect the battery before doing this?
2) From where could I get the connection for 12v? It must not run when the engine is off, only when running.

Images are apreciated as I don't understand English names for engine parts. I will otherwise apreciate any help.

 

look at car PC guides for pictures, but if you look by your pedals, to the upper left of your clutch there is a huge bundle of wires coming through this rubber thing. If you look in your engine bay you can see that same rubber grommet. Its quite a pain in the ***, but Its do-able. You can poke a hole in that rubber thing, or go under it, which is what I did. I stuck a screw driver in there and pried it up and fed the wire through there.

 

If you have enough wire you can go under the car and up through the shifter boot. That is the way the wires for the racing beat gauges reach the engine bay.

 

Thanks a lot guys. What about the 12v connection? (haven't done it before)

 

The rear cig lighter outlet is connected to the ACC circuit. That's where I run my +12v remote wire for my amp. But that's ACC, which isn't connected to the engine. I don't know of any circuits that are fed only when the engine is running.

 

That's ok, I meant that it shouldn't supply power all the time (when the car is off) in order to avoid battery drain. I think that cig lighter will be ok although I have to discover how to get to the wires. thanks.

Do I need to disconnect the battery before cutting the wire?

 

As cited, the console aux is switched (not energized with vehicle ignition off).

Generally Yes, you should disconnect the battery when doing any electrical wire cutting/splicing work. It's low voltage but high amperage and can easily short components with an improper cut or splice. Of course in this case you'll be cutting into a circuit that's not energized so not entirely necessary.
