Title: Permanent live wire
Post by mazzy_j on Apr 20^th, 2006, 2:35pm

Other than from the battery, is there a permanent 'live' connector or wire in the engine bay (preferably which is already fused and near the front headlights)?

The reason i ask is that i plan to fit some LED bulb sidelights which i want to come on permanently whenever the engine is switched on (like on volvos).

Thnaks, Matt

How are they permanetly live, surely they are only live when you switch them on.

You might have to get into the fuce box for the Radio fuse. or ignition.

The only way really is to run straight through from the battery but run it via a relay which is powered from the ignition. Easy enough to do. I run one for my DVD/TV system which runs via a power saver relay so the system doesn't shut down immediately the power is turned off if I go for petrol or something so that Connor doesn't get cut off while watching shark tale!!

I had thought about adding a relay like what i did for my ~~spot~~ flood lights on the front but was trying for an easier already built in option ;)

Could i tap off an ignition controlled 12v from say the pressure limit switch on top of the aircon receiver/dryer, or from a sensor somewhere?? Also, what about the connector from the 'Whats this connector for' topic?

Thanks,

Matt

Wouldn't it be enough to add the extra relay found on scandinavian cars? Or would one need additional wiring?

Tap off the cooling fan relay - this has an ignition feed to it and is behind the RH headlamp (on the diesel).

LEDs shouldn't take too much current but if you're worried then the thick orange/blue wire carries permanent live - you could leech a relay off that...

You could come off the alternator as well but if it’s any where as difficult to access like the cosies then I’d run a mile :P,

i'd stick a small fuse in there where ever you decide to tap off from just be on the safe side
