Hi,

Having read quite few threads on Fuse 22 and various topics on switching thought I'd have a go myself on my DB9 Volante.

I didn't want to start stripping the car to run cables so decided to go for a remote wireless one.

Bought a single channel wireless remote from Maplin http://www.maplin.co.uk/single-channel-wireless-re...
The whole job took about 30 mins and cost less than £50. Now I can switch in or out depending on mood/circumstance/hangover/etc.

Pictures of installation below if anyone's interested.

Connected +/- cables to terminal block on right & pair of flying leads to replace fuse to common and normally closed (n/c) connection. - thought it makes more sense to default to "quiet"


(note in-line fuse to replace the one removed from car)

Connect to Positive connection on top of fuse board and earth connection via fixing stud at the floor

Male spade terminals push into fuse holder.






All tucks away nicely, the remote works fine from driving seat. Overall a nice easy installation.

Interesting. The Paralight (Fuse22.net) box doesn't have the two cables going to your red terminal and ground. It just has the two fuse leads and an earth cable.

Yes indeed. And if something does happen to that little brown unprotected cable that runs from the big fat red cable, that is probably where the fire will start.
I'm sorry if that is an alarmist statement but this is not good practice.

ETA. I'm pretty sure that the Paralight system would not compromise this area
I suspect I'm bound to say I have no affiliation to Paralight blah blah blah

Conversely the Paralight box doesn't even have a fuse or re-use the 20 amp fuse taken from the fuse box. Many people seem to use the Paralight box though. I'm really starting to think that the only 'safe' way to have a switchable exhaust is to pay the factory the £360 + VAT to have a switch fitted, or get a free one fitted by BR if having a service or other work done.

The fuse 22 one takes its power from the same terminal as the one you are switching rather than it's own feed. I considered this but felt it was better to seperate the supply for the two circuits

Might it be worth putting a fuse in the brown wire too then? Are all the wires and connectors 20 amp rated or higher?

Well I don't need a service for a year so I am booked in at the AM works for the switch at the end of April. Seems like a lot of money though. Do BR do the switch at a cost and is it less than the works offering? I understand they are not far from the AM works site.

Can't hurt to ask them - a racing cert they'll be cheaper than the factory!

Assuming that fuse 21 (spare) is not fitted the best bet would seem to me to derive the power for your remote box from a spade terminal inserted into the supply side of Fuse 21 and stick another in-line fuse with it. I'd replace the 30amp one with a 5amp
That way "your" 5amp fuse 21 protects the supply to the remote board.
Relocated fuse 22 protects the existing switching arrangement and wiring.

I've taken that on board, installed 3A fuse in supply circuit already.

This is impressive stuff. Real time modding!

That was going to be my route on my old car, but Sport button does it for me now.

I like your thinking. ...... scratchchin
So I've got to convince Mrs R96 that buying a V12V means I don't need to put a switch in the car.......
I strongly suspect I might be in need of some replacement testicles shortly. nuts

I'm still unsure how the Paralight box is OK if it doesn't use the fuse from the fuse 22 slot. Isn't that dangerous not to have a fuse in this circuit?

Not true. IIRC she's just in the process of getting some fandangled motorcycle contraption.
