Color of pos wire and neg wire pioneerdeh2100

1. OK,GMC/GM are wired as such. White/Black wire, front left -[neg] White, front left +[pos]. Grey/Black wire, front rt -[neg], Grey wire, front rt +[pos]....Green/Black wire, left rear [neg], Green, left rear [pos]....Violet/,Black , Rt rear [neg],...Violet, Rt.rear [pos]........You will also have a Blue/Red wire that goes to antenna. ..A Blue wire for Power Remote....Red goes to IGNITION.....Yellow goes to Battery[for clock].....And finally a Black goes to Ground.......I hope that you have good luck and everything works out for you. `

Black Ground, yellow, battery, red switch battery, blue not used, blue white power antennea/amp, brown tel mute, white black front left neg, white front left pos, gray black front right neg, gray front right pos, green black rear left neg, green rear left pos, purple black rear right neg, purple rear right pos

lf pos is white lf neg is white/black stripe, rf pos gray, rf neg gray/black stripe. amp remote turn on should be blue/white..

black - ground, red - switched or ignition, yellow - constant (memory) power, white - left front spkr pos., white/black - left front spkr neg., gray - right front spkr pos., gray/black right spkr front neg., purple - right rear spkr pos., purple/black - right rear spkr neg., green - left rear spkr pos., green/black - left rear spkr neg, blue - antenna remote, blue/white amp remote turn on.

Here's how it goes:
Speaker wires:
grey=right front pos.
grey/black=right front neg.
white=left front pos.
white/black=left front neg.
violet=right rear pos.
violet/black=right rear neg.
green=left rear pos.
green/black=left rear neg.
red=12 volt switched power source
yellow=12 volt constant power source (direct to battery)
black=chassis ground
orange/white=illumination (switched source,not to head light switch)
blue/white=amp turn on lead (to remote turn on lead of amp)
blue=auto antenna (switched power source)
brown=phone mute lead (to cell phone mute lead)
RCA connector leads:
grey lead:
red=right front
white=left front
black lead:
red=right rear/right rear subwoofer
white=left rear/left rear subwoofer
(connect to external amp)
red lead:
red=right aux input
white=left aux input
(connect to external unit)
green lead:
red=right dual zone output
white=left dual zone output
(connect to wireless head phones)
That should be all there is. on the yellow that goes direct to the battery you need to use an inline fuse holder with 30 amp fuse.

Check the low oil sending unit.(Make SURE there is enough oil in the unit) Take the 2 wires off and join together. If the unit starts, then replace the sending unit and put the 2 wires back on. good luck

The one with the white line is a ground/neg

red---------ignition
orange----constant
black------ground
blue--------remote
green------drvrs front
grn/black--drivrs front neg
grn/red------drivers rear pos
blk/grn-------drivers rear neg
grey pass front pos
grey/blk---pass front neg
grey/red---pass rear pos
blk/grey---pass rear neg

above is link to wiring for 94 legacy , yet another source has a different layout , make sure the colors match your vehicle , 2 sources provided .

yellow/red = hot in on - fuse 17 -15amp
green = interior lights
blue/red = hot all times , fuse 25 - 10 amp
black = ground
yellow/blue = interior lights
black/green = power ant.
red/yellow = right fr neg
brown/white = left fr neg
white/red = left rear neg
blue/yellow = right rear neg
white/black = right fr pos
green - left fr pos
red/black = left rear pos
red/white = right rear pos

if its cutting off and right back on then check your ground and your power wire makes sure both are connected good and none of your fuse's are blown, either that or you got a wire hooked up backwards in the sub.. but my guess is that the sub is hooked up wrong... that sub should be hooked up in a series or in parallel,

ok if your running just one speaker, it should be hooked up like this and 2 speakers are a different way...

this is parallel :pos to pos , neg to neg, then one wire coming from pos on sub to pos on amp then neg on sub to neg on amp but bridge the amp on your amp should be 2 pos and 2 neg in two different channels take the pos off the sub into the pos on 1 channel and then the neg from sub to the neg on the other channel,

this is series : on the sub it will go pos to neg then the other neg and pos will go to the amp, but make sure the pos and neg r on different sides of the sub, dont hook them both to the same coil

if your need more help give me your email and ill send you a pic of how to do it...
