Live supply under bonnet

[xenon]

I'm going to fit a bi-xenon HID kit to my 944 tomorrow (assuming I get it []) and fathoming out the instructions it suggests that the feed to the relays is connected (via fuse) to the battery - all very well aside from the fact that the battery is in the boot.

Anyone know where I can pick up a permanent +12v feed under the bonnet? Probably about 25A?

Taking it of the starter motor would be your safest bet.

I don't understand Rich. The starter, as well as being inaccessible from the top of the car, would only have +12v supplied to it whilst cranking the engine, not all the time? Or is it a switched earth?

There must be a main +12v cable running into the engine bay directly into the fuse box. You could tap into it in before the cable runs into the fuse box.

Link to an old thread that may help. There is a useful schematic about half way down.

I see your point but in my mind is more accessible than getting to a feed at the fusebox or access to the back of the alternator - cant think where else you might get 25A. Yes it is a case of getting under the car, there is a supply direct to the solenoid (on top of the starter) which is permanently live. All you would need is a 13mm spanner, then connect your cable with crimped connector obviously having an in-line fuse 10mins max.

I would tend to pick up an ignition circuit rather than a permanently live one so as to avoid any possibility of a battery drain when parked up.

There wont be any drain as the lights are switched via relays - controlled from ignition/lighting circuit. The problem is where to find a switched 25A.

All sorted. If you lift the fuse box out there are two main feeds (under fuses 1 & 2) direct from the battery. Picked up from there via an in-line fuse.

Hi Xenon

If you have any pics and details of fitting the HID kit would love to hear from your experience as I would like to fit these but was initially put off by the thought of having to get a feed to the battery.

What connection did you use to connect to the fuse box with a fuse?

Thanks

Lee

Hi Lee

I simply used a normal spade connector under the fuse box, there's plenty of room. The hardest part was finding room for, and mounting, the ballasts.

I can't work out how to add pictures on this forum, so see here for some pictures:

Thanks Xenon.

May look into this now later on in the year.
