355 Fuse Box. Where is it?

Sorry for the dumb question but I've owned my 355 for less than a month and the cigarette lighter fuse has blown. I've found the fuse box in the luggage compartment but all the fuses are ok. According to the handbook there's another fuse box in the floor but it doesn't say where.
I've seen a previous post mentioning about a fuse box in the passenger footwell but I can't find one in my car.
Could somebody please help me out and describe where exactly this elusive second fusebox is.

 

Yes in the passenger footwell at the front behind the rubber mat on the upright part. You have ot peel the mat away, undo the two retaining screws at the top (like Zeus fasteners) then IIRC the cover hinges down

 

Thank you so much, you're a superstar

I am looking at this fuse box, scratching my head to find the radio fuse. It's not there. My radio doesn't power on and my first instinct is to check the fuse.

 

The wiring diagrams don't have many clues, either. One of the fuses for the radio is in the luggage compartment (fuse 4).

There are probably one or more fuses in the radio itself. Do you have release keys for your radio?

 

Thanks it's an aftermarket kenwood, and it turns out all the fuses were fine. Probing the constant and ground wires were good, but the accessory wire was dead, so we soldered into an accessory on the ignition cylinder. All good now

 

Can anyone tell me where the fuse is located for the secondary air box. Keep getting a p0410 and want to check the fuse!

thanks

 

It's behind the passenger footrest. Secondary air is fuse 31 shown in the driver's manual on a 5.2 car. Relay "L" (or E10 as it is also known) turns on the secondary air system.

If you have an owners manual, go to the picture of the relay panel and turn it upside down (Australian cars have upside down fuse panels).

If you're getting a bypass valve message and a secondary air message, you may have a vacuum issue or someone has accidentally swapped over the electrical plugs on the solenoid valves (behind the right rear wheel arch). The blue plug goes on the secondary air solenoid valve.
