Guest Posted March 26, 2014 Share Posted March 26, 2014 Hi All Starting to scour round my new Supersport and have seen this harness & connector in the boot (diagonal spar on RHS of body): http://farm4.staticflickr.com/3763/13422566853_0a14fe7a38_c.jpg Is it a case of it could be anything (within reason of course!) or is this a normal place to put, for example, the connector for a third brake light?

alan7 Posted March 26, 2014 Share Posted March 26, 2014 What colour are the wires? Looks like one is Red/White which is usually instrument illumination that is live when you turn on sidelights/headlights. Al Link to comment Share on other sites More sharing options...
Area Representative paul richards Posted March 26, 2014 Area Representative Share Posted March 26, 2014 I suspect it could be the lead for a 12v power socket. The wiring is normally around that area (Caterham fit the socket on rear bulkhead). If not used, wiring is usually under the boot floor. Give it a test with a meter or a bulb and a bit of wire. If 12 v power feed it will probably operate on first position of ignition key. Link to comment Share on other sites More sharing options...
Domus Posted March 26, 2014 Share Posted March 26, 2014 I used it to power Mrs Domus' heated waistcoat It is fed from a blank space in the fusebox, it is marked up at 20A (I think) I used a 3A fuse as that is the load on the jacket. The jacket has several settings from min to max. It has been christened Max by Mrs Domus. 😬 Link to comment Share on other sites More sharing options...

ChrisC Posted March 26, 2014 Share Posted March 26, 2014 My guess is It's the official power socket wiring, and light. I found mine in the boot of my 2011 sigma. Link to comment Share on other sites More sharing options...
Guest Posted March 27, 2014 Share Posted March 27, 2014 Thanks all Have yet to run a bulb or meter to them, but did grab a clearer pic last night whilst cleaning out the boot: http://farm8.staticflickr.com/7142/13441568084_160758343d_c.jpg Link to comment Share on other sites More sharing options...
Grubbster Posted March 27, 2014 Share Posted March 27, 2014 It's an unswitched power supply, I used it for my intercom Link to comment Share on other sites More sharing options...
Guest Posted March 27, 2014 Share Posted March 27, 2014 Quoting Grubbster: It's an unswitched power supply, I used it for my intercom Excellent, although excuse my numpty-ness, but is this the case for both connectors? Link to comment Share on other sites More sharing options...
Roger Ford Posted March 27, 2014 Share Posted March 27, 2014 Red and white normally indicates lights - should be live whenever sidelights or main lights are on. You have a multimeter I trust? Link to comment Share on other sites More sharing options...
Member Jonathan Kay Posted March 27, 2014 Member Share Posted March 27, 2014 As above. My guess is: Red/ white: Feed switched with sidelights Purple/ red: Accessory feed switched with ignition Black: Earth That's not quite consistent with Grubbster's findings but it should be close enough to let you (and the meter) work it out. Please tell us what you find. The current wiring diagram for "all standard instrumentation, Ford Sigma variants" has these as PR179, RW89, B 15. Let me know if you'd like a copy.

Guest Posted March 27, 2014 Share Posted March 27, 2014 Okay well I think it's top marks to the majority of the posters above as you were all correct. So after dusting off the multimeter (and remembering how to use it... ) I have found the following: Red/White - 12V when side lights are active (erm, what's the point of this? To add more lights?). Purple/Black - this is permanently at 12V so I assume wired directly to the battery (works with ignition on or off). This would be the same as my 12V socket in the dash. Thanks to all for their advice & direction Link to comment Share on other sites More sharing options...
Member Jonathan Kay Posted March 27, 2014 Member Share Posted March 27, 2014 Well done, and thanks for the answer. I'd expect Purple/ black to be right rear speaker but it is a 7! :=) The sidelight-switched feed can be used for internal illumination of instruments. Or lots of blue LEDS to add presence at night...

Roger Ford Posted March 27, 2014 Share Posted March 27, 2014 Or you could connect it to an LED boot light so you can see what you're doing when rummaging in the boot in the dark. Getting it to turn on when you "open" the boot might be more of a challenge, though! Link to comment Share on other sites More sharing options...

Purple/Black - this is permanently at 12V so I assume wired directly to the battery Edited to say that the 12v feed when sidelights are on is simply to light the socket and other is 12v feed for socket. note to self - don't reply when pi$$ed.
