Need it spelled out for me like a first grader....

Ok, so I am wanting to put in a pioneer head unit into my festiva. Here are the wires that come out of the pioneer with the black adapter on the end. And then here is what the wires look like that are unplugged from the oem stereo that is in my festiva. Now the million dollar question, what is the easiest way to get these two sets of wires together to make the pioneer work? Is there an adapter that I could just plug everything into and make work? Thanks, Jim

Yes get the wire kit it will look just like your 2nd pic you will combination those with the plug from the head unit the just plight in both ends.

[skimsucka]

you have to use the color designation diagram from the pioneer paper work and the corresponding paperwork diagram for the adapter and match by their speaker / power label splice together and plug in!

Speaking from experience, I would cut the wires coming out of the Pioneer connector in half, release the terminals from the male Festiva radio connectors in the right hand thumbnail, crimp new solid brass Yazaki 2 sq mm open barrel Male Tab Terminal - $0.12 ea that I have from Eastern Beaver onto the Pioneer connector harness and push the spades into the appropriate Festiva connectors. It would look like it came like that from the factory, it would be a simple plug in and there would be no danger of having a short. You could plug the original Festiva radio back in within five minutes.

The only thing I have to add comes from recent experience with two different, new, Pioneer radios I installed in an 89L. The "constant 12v" wire. The Festiva side harness I bought off ebay connected this to a yellow wire in the car side iirc. Both radios would distort heavily at moderate levels and at fairly low levels on certain recordings. After a long battle, I found that the yellow wire could not supply enough current to fully power either radio. I moved it to a better 12v connection under the hood and all worked great. I don't know if it was just my car or not. The yellow wire in the dash wiring was of smaller diameter than the others. Just a heads-up in case you encounter something like this. John

Is the Scosche wiring harness just like in the link with connectors only on one end?

That would be similar to the right thumb in the first post. The Scosche harness is missing one connector in the link.

I think the yellow wire is intended to just store your channel settings and keep the clock accurate. Shouldn't need much voltage.

I found this online...what do you think of the sentence where is states you need to wire a fused constant power supply from the battery for the radio to work properly?

The 12-volt input is required for the radio to function and is energized anytime the ignition key is turned to "ACC" or "ON." For the AM-only model, the power is routed through a 15-amp fuse that is shared with the cigarette lighter, and is blue with a yellow stripe. The first power wire on the FM model is set up exactly the same as the AM model and also blue with a yellow stripe. The second 12-volt input on the FM model shares a 10-amp fuse with the interior lighting, and is white with a red stripe. If installing an after-market radio, it will be necessary to wire a fused constant power supply from the battery in order for the radio to function properly. The ground wire for each radio setup is completely black and is grounded to the car body just behind the dashboard.

Well all the radios I installed need the yellow hooked up to even turn on

[Team Lightning]

Most of the new radio's I've installed needed 2 power wires. One that is switched for turning on the radio, and one that's always on for the memory. It's for holding the stations and volume you had when you turned it off among other things.

[jawbraeka]

i understand that if you hook up standby to the mains, this will allow you to turn the radio on even when the car is switched off.. no need for the other one as the stand-by is always powered.

[bravekozak]

The Festiva radio is very simple.
The blue/yellow wire is the main power wire and turns the radio on and off.
The red/green wire is for the lights behind the buttons. It comes on with the parking lights and is non-dimmable because everything in the radio is grounded through the black ground strap in the back of the radio.
The single white/red wire (always hot) is for the memory.
The other two four position connectors are for the front and rear speaker wires.
Two wires per speaker.
That's all folks.

Both my att and power wire are hooked to a constant power source. Dont need key to turn stereo on. I made a mistake the first time and wired to the radio light wire in the dash, this blew my fuse and my lights, brave bailed me out and help me reconfigure. My wires had been hacked by PO and i had a hard time making sense of it all.

[sasquatch]

the yellow wire on the deck is what will draw the most current when the radio is on... (there is a reason its thicker wire than the red...) the red wire will turn the deck on with the key.
