1998 Infinity Sound system, Which Wire on the harness is switch 12v

[Lordpaxin]

Hello just wondering if someone might know the wire on teh stock headunit that is the switched power, 1998 Infinity system.

 

[gurmanator]

the red wire(10 or 12 guage wire).use a test light to check wires.you can use any power source you want just as long as it turns on with the key and turns off with the key and a test light will tell you that(red means power).

Use a multimeter and and turn the car's keys to accessory. Depending on who messed with your system, I never just trust color of wires. Use the multimeter and look for voltage. After you found one, turn off the keys with the multimeter still on the wire, if it remains for over 10 seconds that is your switched power. Constant will stay on.

Remember, usually power and ground are on the outsides of the harness on cars. Aftermarket head-units are typically red(switched power) and yelllow is constant.

Ah, yes. New car. Step One: Tunes.

Lol actually I was thinkin about tapping into that wire for the Power for my Electronic Boost Controller.

As for tunes, Yes, every drive i take a yearn for a little better abience.
with buzzing comming from here, and rattles over there, and the stock (i think ill only pickup radio within 30 mile radius) and the lovly rejection of burnt cd's I have the entire system i had in the 3000gt sitting on my floor, but Cutting and splicing into the Amp wiring under the passenger seat is a little more of a job than i have time to dick with it right now.

I work at TOYOTA midnights
7:15 pm -> 4:00 am with 35 min travel 1 way = no time and my weekends are spent with someting alittle warmer and softer and moister than a car, .

Am i wrong, but doesnt the Infinity system have a Din style cable taking the signal to the Amp to be split into the different channels? There for you have to tap into the wires After the amp?

thats how the 3000gt was.

There's one DIN cable going to the underseat amp, and another going to the rear CD changer. However, the radio plug above is what feeds to the radio.
Are you trying to hook up a stock stereo, or are you going after-market? If after-market, get an adapter plug that hooks to the radio's harness and plugs straight into the factory socket. You'll need to add a ground wire from the new stereo, as the factory grounds through the radio chassis straight to the frame.

Im going to stick an aftermarket in soon, but no hurry.

I always thought the Stock stereo did Not break down into the 6 channels Just the signal, and the Amp cuts the singnal to the component speakers,

I had to Jumper to the cd player down from the Amp outputs to the speakers to get the channels out. on the 3000gt. and i had to eliminate either the doors, or the tweets, cause it would have been an uneven ohm load.

I don't get how the intricacies of stereos work. However, for the Infinity, the plug in the dash goes to the radio. If you don't have an amp, the speakers are fed off that plug. You have to be equipped with one of the down-market radio options to run it this way- however, my Talon came with an Infinity deck with a separate CD player under it. I, of course, had to have the CD changer. And the amp. Talons don't have the DIN cables, so I had to install those to get the amp and CD changer working. Interestingly, they do have the power lead for the changer tucked into the rear trim.
Apparently there's a set of non-amplified wires to the dash speakers in the Talon scheme, as there are two sets of plugs up there. One comes from the amp, the other straight from the radio. I don't know what goes on inside Eclipse dashes.
When you hook up the underseat amp, it also has a plug for it that feeds the speakers, and feeds the dash tweeters.
I've recently swapped-over to a CD radio which plays MP-3s, and it's hooked only to the in-console harness plug. The amp plug is just left disconnected.

Thank you much.
I kinda have a feel for it now, so ill be ripping into it soon.

I need to get off these dam'd midnights, and we work every other saturday,
