As the title has anyone identified a keyed + in the engine bay ? if so where was it and the wire colour if possible

As ever any assistance welcomed

Engine code please. 

CTHE 1.4 2014

Black/yellow wires going in and out of the 14-way connector pair near the nearside suspension tower, pin 11, is one option. 

What do you aim to power from it? That wire is fused at 7.5A (cabin fuse 3), but that fuse serves several different consumers so you wouldn't want to add much load to it.

@Breezy_Pete

500ma required to power an exhaust bypass valve, I'll research the max current draw on the circuits protected by fuse 3 (shan't be putting a 15A fuse in lol) Thank you for the help (Again)

There are a bunch of other higher-fused feeds that come from the 'main relay' via fuses 28-33 inclusive, which might be safer bets, not strictly ignition switched, but effectively so, they'll be on whenever engine is running.

 

Wire colours/easy access location ? or a copy of the wiring diagram for reference would be great

Fuse 28 (10A) one is on pin 6 of that same 14-way connector blue/black wire one side, black/white on other side of connector pair.

Fuse 32 (15A) via pin 3 on blue/red wires.

Both these wires test +12 permanent key on or off

Can you point me in the direction of an appropriate wiring schematic please ?

How odd. I must be misunderstanding how that relay works. What about if key is right out of the ignition?

 

erWin Skoda for circuits. Individual vehicle information tab, repair info, choose model etc.

1 hour's access is under a tenner and you could download huge numbers of pdfs in that time.

Download links don't appear until 'flat rate' is paid.

Don't forget to allow for inrush current of the solenoid valve - likely to be much higher than holding current.

@Warrior193

That is handled separately by the control unit supplied by a fused supply from batt +, but thanks for the input

 Same (pos 12v) with key fully removed

OK, I don't understand that all. That would imply that either your main relay is switched on all the time* (which seems wrong). Or the wires you're talking about aren't the ones I've tried to describe.

 

* Could be that it gets switched on by door opening, and switches off again when the car goes to sleep after closing/locking??

Which relay do the wires originate from I'm assuming I'm on the correct connector, 14 pin one mounted to Pass side shock tower to the side and behind the battery

 

 

The main relay is on the bottom row of the relay holder in the cabin, in the middle; position #13.

Not sure how easy it is to  access.

 

That is the 14-way connector, yes.

@Breezy_PeteI have downloaded the applicable schematic (after a bit off a faff) and will progress this tomorrow when its a bit warmer

 

Thanks again for the assistance

Outcome of this was

The red purple wire (Fuse SB28 (10A) on pin 6 of T14a (14 way connector on p/s inner wing suspension tower) is indeed a  key controlled + all be it with a delay off by about a minute, I've tapped in to it  (max draw for existing circuit 3.75A, max draw by valve control 2.5A) so electrically fine.

All operates as expected many thanks for the assistance
