Hi,

After a search on this forum, I've come to the conclusion that the only ignition controlled 12v source that's suitable for use with accessory relays is from the cigarette lighter circuit.

Can anyone advise are there other sources?

Car is a UK spec 1998 HSE 4.6

I'm looking to use the source to switch standard relays probably (four to six of them) - the relays will switch the power side of the circuit from a seperately installed fuse box, fed directly from the battery, so I'm only looking for low current switching sources.

cheers,

Vern

The cigarette lighter circuit is ignition switched but is an auxiliary feed so turned off during cranking. An alternative is the common feed to the petrol injectors which is powered from the main engine control relay. This can be picked up at the engine ECU, connector C509, pin 7, a Brown/Orange wire. This won't come on with the ignition switch in position 1 but will as soon as you turn to position 2 and will stay on during cranking.
