87'300E radio wires
Looking to find out what all the wires in the back of my radio are. I can only seem to find the power plug Accessory,illumination,always hot and neg. I can't seem to find what the 1. Black spade plug next to it is for. 2. Then there is another plug with only brown wires I think with either 4 or 5 connectors. 3. A 2 prong connector with an metal clip on it at the bottom left and the 4. 2 speaker wire plugs. I connected a sony cdx2180 radio to the 4 power wires correctly using a chart from sony. I connected the speaker wires using only 1 pos and 1 neg for the front and 1 pos and 1 neg for the rear. The fader button seems to work which I understand shouldn't with an aftermarket system. the radio doesn't hold the memory and buttons are doing funky things. only left fron and left rear speakers work and controls on radio won't work for treb,bal,bass or fade.
Sombody please help with how I wire this sucker up. Thanks in advance Vinnie

Here you go..
1. Ideally, you should bypass the fader. This link: w126 stereo fader shows how. Even though it's for a different model car, the wiring is the same.
2. Which radio do you have exactly? Perhaps some photos? There will be one plug which has four connectors, one connector is offset. This whole plug is the power plug, containing the constant, illumination, ignition and ground connectors. The other plug (with brown wires) could be the Speed-Dependent Volume Control plug, which isn't utilized by the Sony radio. The connector with the metal clip could be another ground connector. |

87'300E radio wires
The plug with the metal clip has 2 pins that plug into the back of the radio with a metal clip that kinda holds it on underneath the radio. Is the large spade plug the antenna wire.
Thanks for your help vinnie

The black spade plug is for the antenna. The metal clip underneath the radio that you speak of is part of the anti-theft system. When installing an aftermarket stereo, ground this wire.
