Duffman Posted September 25, 2008 Share Posted September 25, 2008 I know this has been covered but could someone please confirm the wires I use There is a red, black, orange, white, yellow I fitted the red, black and orange to the back of the radio but no joy Quote Link to comment Share on other sites More sharing options...
Mr. Fish Posted September 25, 2008 Share Posted September 25, 2008 RED - 12V Constant ORANGE - 12V Ignition WHITE - 12V Light/Illumination BLACK - Ground YELLOW - Opt. Negative Warning Output dont put the red and orange one on the same source! Where abouts did you fit them to the back of the radio? Quote Link to comment Share on other sites More sharing options...
Duffman Posted September 25, 2008 Author Share Posted September 25, 2008 Mr Fish - i connected the red, black, orange to the back of the radio (just after the terminal block that inserts into the radio) the only coloured wires i saw on the back out of all the above colours were red, black, orange (yellow was there but i didnt use it). There were loads of wires behind there coming outt he blocks. I saw a white wire as well but I thought this was for speakers or something. I started the car up without the hose connected and nothing happened...I was expecting it to maybe light up. Have I fitted the wires in the correct location? note i have fitted the red and orage both on the back of the radio where it comes out the terminal block) Quote Link to comment Share on other sites More sharing options...
ivan Posted September 25, 2008 Share Posted September 25, 2008 Don't automatically assume that the colours will be the same as on the gauge. The standard (ISO) stereo wiring is Yellow - 12V Constant Red - 12V Ign In which case your gauge orange should go to the radio red and the gauge red goes to radio yellow. Have you got the connection diagram for your radio that you can check against? Quote Link to comment Share on other sites More sharing options...
Duffman Posted September 25, 2008 Author Share Posted September 25, 2008 My radio is a Blaupunkt Woodstock DAB 52 Dont have the diagram unfortunately but im looking on net for it I thot I wasnt to put the red and orange to the same source i.e. the radio Has anyone got a Blaupunkt Head unit that they can supply me with the wiring diagram Quote Link to comment Share on other sites More sharing options...

Have you got the connection diagram for your radio that you can check against? Connected the wires up again and still no joy Red (Gauge) 12v constant - Yellow (radio) wire said '12v memory' Black (gauge) ground - black (radio) Orange (gauge) ignition - red (radio wire said '12v ign' take it that means ignition White (gauge) illumination - orange (radio) wire said 'illumination' Yellow - nothing Then connected the t'piece in the correct position, started it up and nothing on gauge...although the engine was idling unusual and at lower than previous revs. Removed all t-pipe connections i had fitted so it was back to normal and took it for a drive...it seemed to pull alot harder than before and im thinking that maybe i have f*ed up the boost. Has anyone got any idea whats going on or if you are nearby i could come to you and you could perhaps lend a hand Please someone give your knowledge Edited September 25, 2008 by Duffman (see edit history) Quote Link to comment Share on other sites More sharing options...
ivan Posted September 25, 2008 Share Posted September 25, 2008 Well at least the wiring looks correct at last. I'd be more inclined to think the previous dodgy wiring attempts might have f'd up the gauge ECU. Next step is to get someone local who knows what they're about to take a look.

Duffman Posted September 25, 2008 Author Share Posted September 25, 2008 i wasn't sure if the yellow wire '12v memory' on radio was correct...whats it on about memory for?...or is this right enough? you know of anyone on here who is local to glasgow area who might take a look and help me out?

Duffman Posted September 26, 2008 Author Share Posted September 26, 2008 think its wired up correctly now so dont have a clue why it aint working at all...not even lighting up the radio is working so its defo getting power Quote Link to comment Share on other sites More sharing options...
Mr. Fish Posted September 26, 2008 Share Posted September 26, 2008 (edited) so all the connections are good yeah? you havent got a dodgey ground or anything? on my headunit yellow was always ignition and red was live....the 12v memory sounds a bit odd tho... did you try it with your lights on/off...as when you turn them on, it will illuminate and vice versa....sorry if im making you sound silly..but the gauge isnt going to be moving when your idleing/not driving.. also have you got a pic of the back of your HU, where you have connected it up? may help Edited September 26, 2008 by Mr. Fish (see edit history) Quote Link to comment Share on other sites More sharing options...
Duffman Posted September 26, 2008 Author Share Posted September 26, 2008 ill get some photos up today tried it with the lights on off but still nothing...no worries u dont make me feel silly ive done that all on my own cheers Quote Link to comment Share on other sites More sharing options...
ivan Posted September 26, 2008 Share Posted September 26, 2008 "12v memory" just means that it's permanently live to keep the radio settings etc in memory. It's why you have to reprog your radio if you unplug the battery. Quote Link to comment Share on other sites More sharing options...

It's why you have to reprog your radio if you unplug the battery. yeah found that out 2day cheers mate its all wired up correctly but still not even lighting up never mind the needle moving...think it may either be the Data Link Unit (grey box) or the gauge itself. Gut i bought it off is sending me another DLU so i can see if thats the problem...if not then its the gauge itself. Also when I connected everything up correctly i.e. wiring and all hosing...I and started the engine and it did not sound very smooth at all when on idle...does anyone know why this is...sounded as if it were gonna cut out was hardly any revs Quote Link to comment Share on other sites More sharing options...
Dazzi Posted May 4, 2009 Share Posted May 4, 2009 Sorry to bring this back but what is the purpose of a 12v constant source for a boost gauge? Mine (not greddy) says I need to wire the red to a switched source (ignition) and the yellow to a constant source... would it cause problems connecting both Red and yellow to a switched source?

Hopefully someone with a bit more knowledge can answer this one but yeah i'm pretty sure it would cause the gauge to work incorrectly. Think it might be something to do with the gauge switching on when the cars switched on (switched source) and being able to light up when the cars off (constant source) Quote Link to comment Share on other sites More sharing options...
Dazzi Posted May 4, 2009 Share Posted May 4, 2009 Great, that helps. Well I just wired the constant source wire to the yellow wire on the radio and everything works great. I noticed when I turned the ignition off the gauge had a shutting down sequence i.e did its stuff for a few seconds when the car was off Quote Link to comment Share on other sites More sharing options...
merckx Posted May 4, 2009 Share Posted May 4, 2009 what is the purpose of a 12v constant source for a boost gauge? Maybe it's to maintain a user adjustable warning level for the gauge. A good source of power is at the radio power supply, yellow is permanent , red is ignition power. Quote Link to comment Share on other sites More sharing options...
