Hi just a quick question if anyone can help. I'm looking for a permanent live unused or if necessary used fuse position in the front under bonnet fuse box. There is nothing in position 48 would that be OK? . Many thanks.

A quick glance at the fuse sheet shows that 48 isn't used by anything, so you should be ok

Failing that, go direct from the battery with an inline fuse....
Bummer !!. Looks like none of the connections there are permanent live so I guess it's straight to the battery as you suggested Seanhump. Thanks

Check again, there are definately permanent lives there !
Thanks Curro I'll check tomorrow, at work now. Any ideas which are live?. Thanks.

I wired my fused DRLs to the power distribution block. Seemed to me more convenient than going directly to the battery.

Hi PitchRate really helpful pics and something I hadn't even considered. Which terminal did you connect to ? or doesn't it matter. Also did you just use a ring terminal under one of the nuts. Thanks

I'll try and check tomorrow for you !
Thanks mate. Appreciate it.
From memory I'd say it's 62 or 63, it's one of the ones nearest to the bulkhead...
Well I found a couple of permanent live in the fuse box and also tried connecting directly to the battery. Now the drl's stay on all the time so I think it must be a faulty controller. Thanks everyone. If anyone can recommend a UK based drl controller supplier I'd be grateful.

What started all this was my fitting drl's but I wired them originally from a switched live fuse but they will not dim when turning on the sidelights. I thought maybe it was because I had not wired to a permanent live but having done that as I said in the last post the drl's just stayed on. I have had another thought however which I'll try tomorrow, I use led sidelights and it's possible the low amount of amps they draw is not enough to trigger the drl controller. Let's hope.!!!!
On my 55 there is a black and yellow wire in the fuse box in the engine bay.
This becomes live when the key is turned to start the engine.
I have connected my drl controller to this wire, i can turn the engine off and listen to the radio etc but the drl's will go off, so when parked up, no lights are on.
My drl's also dim when my lights are turned on.
The battery connector photo above has a spare way at number 1, the nearest the front of the car. I use this for a permanent connection to my Optimate battery conditioner.
I hope this will help?
You need a switched live for the main power unless you have the type of controller that connects to the battery and senses engine start. The black and yellow wire Russ suggests is the one I used as per instructions for my Piecha DRLs

I have a hunch that maybe your trigger wire connection to the side lights could be the fault, so re-check that connection. Check the instructions that came with your controller and if it's wired correctly and all connections are sound then it looks like it's a duffer!

Another thought. Are you sure the LEDs you have are dimmable? Not all are.

Col and myself both have LED side lights so that should not be a problem
Just looked at my dimmer (white) wire and the wire colour i have connected it to, looks to be white with a red stripe.

Looks like you already tapped into the block. Yes I did use a ring under one of the terminals. I have Phillips LEDs and controller. My controller automatically turns on the lights when it senses current from the battery. It is also wired into my side marker lights which then turns off the LEDs when my light are on.

Good stuff everyone and a big help....thanks. I reckon I have a duff controller so I'm sourcing a UK built one locally which works off switched live and hopefully that will sort it. I'll keep you updated and thank you.
