i tried to install the pioneer d3 into my 08 civic si, i have no sound / my passive alarm now wont work / power locks wont work unless the key is in the ignition / interior lights wont light up when the door opens / and the yellow wire which is supposed to have constant power doest have any at all . i think it may be a fuse but if anyone can throw any ideas please help.

 

your main fuse has blown

i tested that fuse several times with a meter then i had several other radio installers check every fuse in the car and they all are fine, but still no power to the moon roof, power locks, radio, and dome light ...

 

Cut the wrong wire maybe?? good luck with a fix

 

Thats why we pay $50 extra for professional install. They mess it up they fix it! LOL at you! Anyway GL!

 

yea your rite I never had a problem before..I just got the car back and they claim it was several fuses but I checked all of them visually and with a tester..o well I guess as long as its fixed

 

I told you it was a fuse.

 

thank you for your help anyway
