SupraStar 3000 Posted February 16, 2007 Share Posted February 16, 2007 Just a quick question. This weekend I want to fit my gauges. For power I require: 12V battery wire 12V ignition on 12V lamp on Ground since the stereo is right above this unit, can I splice wires off the ISO connector which already have all the connections i need?

merckx Posted February 16, 2007 Share Posted February 16, 2007 Yes I'm not sure about the illumination wire - 12V lamp on Link to comment Share on other sites More sharing options...
SupraStar 3000 Posted February 16, 2007 Author Share Posted February 16, 2007 Cheers mate. I'll give it a go Link to comment Share on other sites More sharing options...
Supradoopa Posted February 16, 2007 Share Posted February 16, 2007 Sorry to hi-jack this thread a bit but I need to extend the wire leading to the dc source on the defi control box. Can I use any wire or does it need to be rated, i've got some wire rated up to 6A will this do? Cheers for the help Pete Link to comment Share on other sites More sharing options...

Ed mate, the 12V battery will retain the memory so that will be separate to the 12v ignition and 12v lamp which you can run from the same source. The use of a voltmeter will ensure correct identification of the 2 circuits Try and 'ground' the wire to the 'circuit' ground wire (i.e. the -ve that's in the harness loop) instead of grounding it direct to the chassis.

Different gauge, but I used the cig lighter as the 12v ignition and the astray light (easy access) for the 12v lamp. My gauges have both live and ground for the ilumination so connecting to the ashtray light means they dim with the rest of the lights. Link to comment Share on other sites More sharing options...
SupraAyf Posted February 16, 2007 Share Posted February 16, 2007 cheers mate so whats the benefits of using the 'circuit' ground wire rather than 'chassis' ground? There is only one final ground location on a car in terms of electronic circuitry and that's the -ve terminal of the battery. If you have an electronic item that is fitted in to a standard car system (i.e. stereo wires in this case), then you should always use the same plus and minus to extract your source from as the electrical efficiency will be maintained in the same circuit. Grounding to the body brakes the efficiency (only slightly) and that's why electronic firms normally insist that you use both circuit wires (i.e. +ve and -ve) to plum in their gadgets.

SupraStar 3000 Posted February 16, 2007 Author Share Posted February 16, 2007 Cheers SUPRASUZUKI I'm sure I'll find a easy way around it. For a NA car my dash I choc'a with wires SLD, Glo Dials, Road angel, Stereo, ipod, BLC, fogs, alarm etc etc,... Link to comment Share on other sites More sharing options...

Good advice mate. I've heard that before (but forgoten it). Makes sense.! Cheers dude Link to comment Share on other sites More sharing options...

SUPRASUZUKI Posted February 16, 2007 Share Posted February 16, 2007 Some people use the clock wiring I thought about it, but for some reason I couldn't drag it far enough out to work on. The ashtray wires were just lying there begging to be spliced:) Link to comment Share on other sites More sharing options...
RobSheffield Posted February 17, 2007 Share Posted February 17, 2007 If you take the dash off its very visable, but i guess the ashtray works Link to comment Share on other sites More sharing options...
