Run a ground wire to that headlight. If it gets brighter, there is a problem with the ground in the wiring harness.
YES IT HAS A PLUG
You have to go purchase an aftermarket wiring harness. that will plug into the factory harness then you can wire it to the aftermarket radio.
the harness
find wiring harness in the back of the vehicle the same one that goes to the tail lights wire it through that wiring harness use test light to make sure you arein the right wiring harness
Unfortunately you would need the wire harness. So either get a new harness or a new radio.
when you buy the harness to wire in, the intructions for correct wiring will be on the harness packaging
Your best bet would be to call or go to your local auto parts store and tell them you need a "plug in" trailer wiring harness for your vehicle....these are very nice items and easy to install, as you just "plug" them into your exsisting vehicle's wiring harness. No need to "search out" for which wire goes where and no splicing of the wires either. They are more expensive than a "standard" wiring plug, but the "extra" cost is more than worth the "time" and headaches you will save!
The easiest way is to buy and install a plug in wiring harness available at most parts store.
The oxygen sensor is connected by a wiring harness. The wiring harness contains the signal wire. The signal wire goes to the system computer.
If you are looking for the 3rd gen they are two blue loops of wire on the harness that is just below the master cylinder on the wheel well.
