Ignition pick up wire

[Squizz_77]

Hi, I am wanting to fit some accessories to my vehicle ( 2005 Diesel R51 ) in the engine bay which needs to be energised by the ignition on only, can any one help to tap into an easily accessible point to which I can draw off, which needs to be 30amps.

 

Looking forward to any suggestions.

30A is a lot to ask of factory wiring. Unless your model has something special I don't know about (I've never even seen a diesel R51!) you'll need to add a relay off the battery that's switched on by the ignition. I would check the under-hood fuse box or other relays in the engine bay for your ignition signal. The relay will put a very small load on whatever you hook it to and the relay will handle the 30A load from the battery to your accessories.

 

Don't forget to add a fuse to the 30A circuit as well.

Something like this should help you. Obviously you need a relay to power the accessories you want to run with an inline fuse to the positive terminal and your switch will go to that relay in order to turn things on/off.
