2001 626 LX stereo help

[Xtreem]

well i usually goto www.mazda626.net but it seems there site is down so i hope u guys could help...


i took out my Head Unit(the giant one) out of my 01 Mazda 626 LX and clipped the old wire harness and went to go match up my wires, i had a diagram for the colors so i got all my speakers wired up right, but my old head unit used a 12v ACC(power) and a 5v constant for memory, the new decc(like most) uses 12v constant(memory) and 12v ACC(power) and i have blown countless fuses and am tryin to find a good 12v source to tap into and also how to checc to see if the decc is good...
(the decc is a pioneer and as i understand the ground is the top of that clip and the yellow below it is the 12v constant?)

You should ground the new deck directly to the chassis instead of attempting to use the wiring harness. There should be plenty of metal parts you can bolt down the ground cable to inside the dash.

Yellow on most modern head units is 12v constant and red is 12v switched. If you are having trouble determining which is which on the factory wiring harness you should pick up a multimeter at RadioShack for about $20-30 and measure the voltage of each wire until you find what you're looking for.

ok, also, in the harness for the new decc, it did not come with a yellow and blacc in it(the kid gave it to me for free) so how can i go about safely putting new wires in

If the harness for the deck doesn't have those wires, you will have to hunt down the instruction manual for the deck to find out which wires you need to use.
