    My tape adapter I've used for almost 10 years died (or the tape deck bit the dust) recently. So, I bit the bullet and bought a Scosche faceplate/install kit along with a new Pioneer digital media deck (USB/AUX/Bluetooth/etc.) I mocked up everything and it all looks great. The deck is barely 3" deep, so there shouldn't be any fitment issues. Just have to pull apart the OEM radio and move the knobs over and crimp all of the wiring harnesses together.

    I was familiarizing myself with the instructions of the new deck, and it mentions that I should connect the stereo's ground wire (from the Pioneer harness) to it's own body ground. According to Pioneer, failure to do so may cause a fire. Yet, looking at the Schoche kit, the large harness has an extra black ground wire (I assume it's for the stereo ground...?).

    Is it safe to connect the ground from the stereo to the available ground wire on the Scoche kit? I don't want to torch my Escort and cause a fire. The last car stereo I installed was at least 16 years ago, so I'm a little rusty. I wanted to ask the pros here for their opinion. I'm stoked to get this thing installed soon. Thanks in advance.

    All I can think of is that the original ground wire for the OEM radio was probably meant for about 25-40 watts of audio power. If your new system puts out a lot more audio than that, if might need a ground wire able to handle more current. After all, a 1000 watt amplifier can conceivably draw almost 100 amps. Briefly.

    No amps, no subs. Just a stereo I can hook my MP3 player up to. The Kenwood speakers (installed almost 4 years ago) are 30 watts each for the front and 80 watts for the rears. Peak wattage is higher, obviously.

    So I should be good? The Pioneer I'm installing is capable of 50 watts per channel.

    I read the instructions a few more times; the diagram shows using the separate ground for an amp, but there might be a typo in the verbiage of the instructions itself (it states when installing this unit or power amp). I'm thinking it will be safe to wire the ground into the available wire on the Scoche main harness.

    if you are simply swapping the headunit all the factory wiring will be just fine. no need to worry about burning it to the ground. just make sure all your connections are secure.

    Install went fine. The right-hand radio clip didn't want to disengage, but finally got the radio out. New stereo works great.
