I've marked the terminal that was used with a yellow arrow. It's in the fusebox to the right of the battery (looking from the front of the car).

Don't forget to disconnect the battery before working on the connection and also put the cable protector on ;)

You can also see the inline fuse holder in the picture, a different design to yours but doing the same job.

When you've made your connection try to secure your new wire to the existing wires with cable ties.

Thanks,

My fuse box had a cover on it!

Found it.

So I need to disconnect the battery first? How does one do that?

and I can't find anywhere to earth the sub - there are a few bolts nearby but they seem to already have yellow/green wires 'earthed' there. Can you earth more than one thing in that place?

Thanks

You need to remove the front battery connector. Pull the red tab up and lift the connector off - no tools required.

The earth connection is best done inside the car, less likely to corrode. If you've found a place were other earth wires are connected then that's the place to go for, so long as your connector will physically fit with the others.

Don't forget, the wire from the battery needs to be connected inside the car before you make your connection under the bonnet.

Ok - great.

So I will connect the earth at those points.

My next issue - the way I connect them. In my pack, I received some 'U' shaped fixings to crimp onto the end of the wires. Think they are called fork connectors.

Can I use these to fix to the bolts, or do I need to get ring connectors?

Thanks

Perhaps you could post a photo of where you are proposing to make your earth connections?

Forks will do the same job as rings, it just means you don't need to take a screw out completely to get the fork in. What you do need to do though is make sure there is a washer between the screw head and fork or you could put the fork under what ever's already connected to the screw. The metal on crimps is quite soft, when you re-tighten the screw the prongs of the fork can spread and come out from under the screw, especially at the side which is being pushed against by the screw turning. Rings do have a slight advantage but forks will be OK if you're careful.

Right - I used a ring connector for the earth.

Last thing - connect the power to the battery.

I cant disconnect the battery.

I tried it. I presses the lever, and pushed down on the red thing to release the catch, the red thing came away, and the battery wobbled when the lever was pressed, but I cant seem to lift it out. Do I need to lift it out?

Thanks

You don't need to take the battery out of the car, just disconnect the positive (+) terminal.

Ah - all I need to do it disconnect the red bit.

So - I did that,

But I cant see how to connect the ring connector on my power line to the nut in the fuse box. I cant really get to it.

Is there some kind of special tool I need to use?

I can just about get pliers to it, but they are at an angle and the nut is done up so tight, that when I squeeze, it just keeps slipping off!

Does the fuse box come out?

Thanks

Don't attempt to take the fuse box out. It has various electronics on board which are best not disturbed.

The ideal tool would be a socket wrench with the correct size socket for the nut. You may be able to use a spanner of the correct size. Pliers will more likely end up damaging the nut and rounding the corners off.
