Dec 1 Posted April 4, 2004 My new headunit has a smart volume line in; through iso plug A1.....(adjusts stereo volume in relation to the cars speed)....is it possible to connect this to the speedo in the car?...if so does anyone know which wire behind the clocks (colour coding?) to connect it to???? It's a 1990 16V by the way!! Quote Share this post Link to post Share on other sites
Henny 0 Posted April 4, 2004 The speed sensor wire for the stereo in a Corrado is blue with a white tracer... Don't be too suprised if your spoiler stops working automatically once you've connected it up though... :? :roll: Most people just tape this wire up and keep it well out of the way as it tends to be more hassle than it's worth... ;) Quote Share this post Link to post Share on other sites
Dec 1 Posted April 4, 2004 hmmm....will give it a try I guess.....as long as the spolier will start working again if I disconnect the stereo from it!!!! :roll: :roll: :roll: Quote Share this post Link to post Share on other sites

Dec 1 Posted April 4, 2004 Ok...Thanks!! Will give it a shot tomorrow, when I can see what I'm doing :) Quote Share this post Link to post Share on other sites
G60Jet 1 Posted April 4, 2004 MY OEM german radio for my C has this function, turns the radio up as you get faster. it just depends on how the unit you've handles the signal. Quote Share this post Link to post Share on other sites
dubbprince 0 Posted April 5, 2004 is this blue/white speed sensor wire in the incoming loom for the OE stereo?? or do you specifically have to cut it from behind the dash once you find it? Quote Share this post Link to post Share on other sites
Kevin Bacon 5 Posted April 5, 2004 A diode might help on the end of the blue/white wire so that current is allowed into the headunit but the headunit can't put current back onto the wire, upsetting the spoiler box. Haven't tried it, just theorising :lol: K Quote Share this post Link to post Share on other sites
Tattie 0 Posted April 5, 2004 The blue/white wire is part of the normal wiring loom, just as mentioned, not used very often. IIRC it was especially for the Blaupunkt Gamma radio. Quote Share this post Link to post Share on other sites
dubbprince 0 Posted April 5, 2004 ohhh....my alpine 9815RB unit is connected to the normal loom...but i guess theres no speed sensor wire on the alpine then for it to take full effect. I have the old blaupunkt....might just ave it in one day to show off that volume increases as you speed up.. I know my cousin had it as standard in his 95 prelude vtec. :cry: Quote Share this post Link to post Share on other sites
