stevebh 0 Report post Posted January 5, 2007 So I finally got around to ripping out my standard head unit out and install my kenwood. Been looking for ages to find a wiring loom, but no luck. So i decided to cut the wiring loom off. Connected the power, acc power and ground wires to my kenwood, made sure there is power going to the head unit, i.e i can eject and load a cd but the dispaly is just not showing up and nothing seems to work, connected a specker up but no sound. Have you guys got any idea as to what the prob could be or maybe know where there is a wiring diagram so i can identify each wire of the bmw wiring loom. Hope you can help Quote Share this post Link to post Share on other sites

It's only ~$60 to get an auto electrical workshop to do it for you.. as long as you haven't made a mess of the factory loom too much. Quote Share this post Link to post Share on other sites

hotwire 352 Report post Posted January 6, 2007 Cheers for the offer mate but im down in Chch . Im sure i will be able to sort it sooner or later. Will keep you posted cheers Sounds like you may have no acc supply to turn it on - did you short something when cutting wires & blow a fuse?, has the headunit got a fuse on the back? Also check for a reset button on headunit -somewhere on front behind face if fitted. If both power supplies & an earth are present & other suggestions are OK then must be a faulty headunit Otherwise as already stated - see an auto sparky - simple job for those who know Quote Share this post Link to post Share on other sites
joshnz 2 Report post Posted January 6, 2007 the small rectangular metal plug is the stacker plug, in most cases unless you have a metal box in the back under the stacker you wont have an amp. the speaker wires are the ones that are twisted and are blue and yellow in colour, permanent is red with a green stripe or just red, purple is accessories, brown is ground, white is antenna trigger (be very careful as some white cables with a stripe are the data bus wires and if connected you can damage the vehicles computers). grey is ilumination that may help a little bit Quote Share this post Link to post Share on other sites

BM WORLD 1286 Report post Posted January 7, 2007 use a volt meter to test where there is power , never hook up stereo's blind . you cant see volts so use a meter .or a bulb with some wires attach one wire to earth i work in the industry and i see lots of blown up stereo's . small hint you can use a 1.5volt aa battery to test which speaker you are hooking up to .

kiwi535 538 Report post Posted January 7, 2007 small hint you can use a 1.5volt aa battery to test which speaker you are hooking up to ..thats a good trick...just hook up the wire(s) and the connected speaker makes a noise? Quote Share this post Link to post Share on other sites
Docile 64 Report post Posted January 7, 2007 yup the speaker should make a *thump* noise.. my dad does it when he checks speakers sides Quote Share this post Link to post Share on other sites
joshnz 2 Report post Posted January 7, 2007 Just make sure when you are doing the battery popping thing that they pop outwards ... well try to at least, thats what I was told by a couple of car audio guys. Quote Share this post Link to post Share on other sites
