Installing Hu Without Harness

[miryde]

Can anyone tell me what color wires are for what on a 01 alero.
-L front
-R Front
-L Rear
-R Rear
-Lighting Switch Terminal
-Ground
-Electrical Terminal controlled by ignition switch (12 V DC ON/OFF)
-Terminal Switch always supplied with Power regardless og ignition switch position.

Any help would be greatly appreciated thansk.

[miryde]

figured this out so far
-L front Light Green +, Dark Green -
-R Front Pink +, Grey -
-L Rear Yellow +, Light black -
-R Rear Light Blue +, Dark Blue -

and I'm thinking
The thick orange wire is - -Terminal Switch always supplied with Power regardless of ignition switch position.

and the ground is the Thick black one

Notes:
Note: This vehicle has the passlock II immobilizer system that, when adding a remote start, must be interfaced with. *1 Remove the radio, without unplugging it, to access the ignition harness. *2 Lock requires a negative trigger, and unlock requires a negative trigger through a 1,500 ohm resistor. Must use relays. Must close doors to lock with a single pulse. *3 Requires a high current ground. Use a relay. *4 The lt. green/black is located in the drivers kick and catches only the drivers door. The lt. blue is located in the harness coming from the drivers running board going under the drivers seat and it catches all other doors. Use both door trigger wires and diode isolate each. On the 2 door the lt.blue is in the passenger kick. *5 The ECM is located under the left side of the dash to the left of the column.

THANKS Jabartram really appreciated.

[slowandlow]

i will never install with out a harness agin makes it a whole lot easyer and if you want to upgrade it is easyer.

[bigd6983]

yea, unless the car is old, and the harness is already raped, its worth the money.....especially if u wanna sell the car and keep ur headunit and put the stock back in

[1WhiteOSV]

there is NO switched ingnition wire in the harness....you will have to run your own to either the ignition harness (proper way to do it) or to the fuse box (easier, lazy way to do it)

[bigd6983]

what do u mean theres no switched wire in the harness, is that something new for the 01's, because my 00 has it

Quoted post


yes...the 99-00 uses the GM 32pin harness (dark blue colored)....the 01+ uses the new style "Tracker/Prism" harness....they ARE different

[dt_freak1]

another thing to worry about is the Class 2 System. either you have it or you don't. I feel mass pity for this person should they have it and they dont know because all their warning chimes will be gone for sure. bottom line, listen for the warning chimes and figure out where they are emanating from. should they be coming from the dash, then your good to go. if they are coming from your driver's side door speaker, then you have the Class 2 Databus and axing your HU will cause loss of ALL warning chimes. My Alero: 01 GL coupe with factory Sun and Sound package and had the Class 2 databus. My system is powered by Alpine and i have all my warning chimes thanks to the GMRC-01 wiring harness!

[1WhiteOSV]

oooh no....no more chimes! what will I do?! So what....there's no way in hell I'd pay $120 for the door chime interface for that....big deal...you have AUTOMATIC headlights so you cant leave those on...and you have auto door locks so you cant lock your keys in your car.....so wtf do u need chimes for?!

[dt_freak1]

hey i didn't pay $120, and besides i didnt wanna run the risk of also losing guages etc, etc. My Alero has an extended warranty and im very picky about things i do to it right now as to not screw myself outta that warranty tyvm! btw, my cost because i have a good friend was $59.95 :D

[1WhiteOSV]

On the N and J body GM cars you only lose the chimes......nothing else.....I put decks in them all day long (i'm a MECP Certified installer at Best Buy).....but nice grab at $60

[jlenko]

Sorry, old thread.... but I had to hop in to find out for sure... I was one of the first to "experiment" on the 2000 J-body to find out that the airbags weren't controlled by the factory radio... just the door chimes.

You say N-body cars are the same... but I've been told by several people that the air pressure monitor is in the deck (this I doubt) and the oil life sensor is reset using the radio (this I know for a fact... I've done it... but it was a W-body).

So... truth to this? Or just myth, like the airbags and everything else..?

[FormulaNERD]

uhhh, in my 99 the oil life reset was the reset button in the drivers side fuse panel.

[jlenko]

I suspect, if anything, it would be the 2001+ N-body.... since the 2000 doesn't seem to have the Class 2 wiring like the 2000 J-body did.

99 definitely would not have it. There is no Body Control module...

[white04alero]

i have a q:
| POWER ANTENNA|dk. green | |at radio |
is that the ignition power? cuz me and my uncle went thru with an indicator light thing.. looks like a screwdriver with a light in the handle and a long black wire hangin off the end.. im sure everyone knows what it is..
anyways.. no current thru the drk grn wire when ignition in the acc position.. all fuses are good.. anyone know why this is? no current in any ignition position.. acc.. on.. or started

[Cliff8928]

Nope, that's where the radio supplies the power to turn on the power antenna (antenna amplifier in our case)

[white04alero]

ok well i did the whole install without a adapter.. and i did not have to use a dark green, 2 purples and a skinny black wire and my stereo worked fine... i just didnt know what the damn ignition switch was.. so accidently wired it to my lights.. i need to kno what the ignition switch is so i can do it right.. any help would be awesome

| RADIO SWITCH|yellow |+ |at radio |
is this it? bc the only yellow one i got in my wires is the one for the back speaker.. thats the ONLY yellow one..

[sound_xtreme]

why didnt you just buy an adapter? much easier, and more professional.
