W203 ACC ?

[Bemmy]

Hi all, I need an ACC feed from the fuse box in the engine compartment on my 2005 W203. If there isn't a dedicated ACC can I use one of the pins on the back of the Horn relay? if so which pin?
If this isn't the way to go any advice would be gratefully received.

Isn't the cigarette lighter in the ashtray fed by Acc? Or is it II 'Ignition On'?

Not sure to be honest but I need something from the fuse box in the engine compartment ideally.

Are you using a Fuse tap? e.g. 2x Add-A-Circuit Fuse Tap Piggy-Back Standard Blade Fuse Holder ATO ATC 12v 24v: Amazon.co.uk: Car & Motorbike
With these it is just a case of finding a suitable location in the fuse box.
What is it you are wanting to power?

Open to suggestions as I have no knowledge!

Just bought some DRL/Indicator LED's from eBay. According to the seller the need to be connected to ACC in the fuse box - that item looks perfect. I just need to know where to plug it into!
