I am in need of a few things


Recommended Posts

I am putting an aftermarket radio and speakers in, and am wondering what color wire is the power signal for from the original. Is it turned on with the key? am at the starting stages of wiring in my pioneer unit and am interested to know what is what.

 Your HOT is the small plug on back of stock radio. Check with a tester, key on/off.   Big plug with multiple wires are your speaker wires.

yet the blue wire runs to the rear and plugs into the deck speaker and has a gray wire to that plug as well. I'll get pics shortly

Gray is your common to all speakers in your system.  Does your original radio work?   You can sell that online.  Check Ebay for going rates, then buy the manuel for the car.

I don't think my stock radio works, tried hooking speakers to the stock radio and go nothing, no signs of life. these are what I have. are those three plugs. my other question is for a more modern replacement, would I put the backlight wire also to the power wire?

So you only have 2 speakers?  One front, one rear?   Should be 2 in rear package tray.  3 total.   NO do not plug radio light into your hot. You'll blow all your dash lights.  Should be a seperate wire for backlight on new radio.  Again, check with test light to find your HOT 1st.  If nothing test hot, check your fuses.

aight. I haven't started wiring. but yeah., it had one deck speaker in the dash and rear

It has a center speaker up front in the dash, and a rear one to the passenger side of the rear deck

My guess would be the green/black  as black is always a ground. Been many years since I've messed with radio swaps.  Do remember a thin plug for GM radio hot.  BUT CHECK IT 1st bro.

I appreciate the help tho. Not very good at wording things in google and my ability to search isn't great when I've been fried. Was working on my friend's second gen ram and helped him put a new trans mount bushing. Not fun. And I mostly need the key signal as I won't be using the stock wires for the speakers. For shits I'm trying some speakers I had. Old NEC speakers, just placeholders plus I have the wiring ran and have basically no budget to get anything as I don't have income and nobody has donated to the gofundme I have going for this car.

We all start somewhere.  Find the original hot for the radio.  Do you have a tester or someone to borrow one from?  You will want to use the original hot wire to run your new radio, that way it won't accidently get left on and kill your battery.   If your interested in this stuff,  apply at a car repair garage N work your way up as you go.  Everybody needs help right now.  Just get your foot in the door.  Even dealerships need guys to clean up and get used cars ready for sale N make some pretty decent cash.  They will be happy to teach you what ya need to know.

my issue is I need to fix this thing as it's my only hope for transportation to get a job, there's not much where I live for work. I want to go into detailing or a tire shop. Probably gonna get a cheap harbor freight test light when I can

I still need to get 2 speakers for the kick panels as that's where I want to put them

Test lights are only a couple bucks.   They clip to a ground and when you touch the solid end, it lights a small light in the handle.  Tells you if you have power in that wire or not.  This is a must for any electrical work you do on the car.  Does it run/drive?

It runs, and should drive. I need to get some tires on it as the ones it has are crap, and none are matching, and one's blown and shredded. I have tires for it but no money to get it mounted and balanced

Here's a video of it running. No tires on it atm but yeah. Gonna get some work done soon, most likely body work to the front of the hood so I don't cut my fingers as the release lever is next to sharp metal
