R34 Where To Source Power, Accessory, Illumination

[Charles89]

Hey guys,

I'm going to install my Tein EDFC over the weekend, I'll be putting the controller in my DIN pocket, but I'm just wondering where is the best place to source constant power, accessory and illumination from?

I can splice into my headunit loom or my MFD loom, but is there another easier place inside my dash that has all those wires?

Cheers

I reckon it would be easiest to just splice into the audio. Your installing the controller in the din pocket anyway and the less wiring you have to run the better imho. I used to install mobile phone kits for a living in a past life and it was always an easy convenient source for constant accessory and earth. Not to mention a good place to mount the control box as well. The only thing I would check before you do is the current draw of the EDFC to make sure you aren't going to overload those circuits otherwise take +ive and acc directly from the ignition switch and fuse accordingly.

most of these cars had an accessory 4 pin socket on the radio plug. use that.

Hmmm.. How do I check the current draw on the EDFC?...

Might have a look for that plug you mentioned Chris.

As above, use the radio for your constant power. Switched power can be sourced from the cigarette lighter, while I got my illumination 12v from the ring of light around the cigarette lighter, that's the single pin plug.

Do just make sure you check the current draw, especially if you tend to use the cigarette lighter for a GPS or other accessories, you might find it starts blowing fuses often if you overload it. But I think the Tein EDFC is a simple unit, I can't see it drawing a load of current.

i believe the EDFC takes constant 12V and a wire for ignition... else the settings will reset each time u turn off the engine.

careful how u wire it cos if the current is not stable... each time u crank u might get error beeps...happened on my S13 before...

question! when my headlight is on, edfc is off and my mfd is off
@charles do you know how much v mfd needs? 24v?

cos when the headlight is on, both my acc+power goes ~0v

hmm

fixed! bad ground :$
