White wire behind radio ?

[jeffnhiscars]

I pulled the factory cassette player today only to realize it didn't work cause it was discover it was completely disconnected..not that it matters since I have a new Kenwood to pope in.

Question is what is the twin lug white wire for?

One is for the power antenna, the other for the amp. Refer to this post:

First, let me say this is NOT applicable to all E30s. Generally, Late Model (88+) will have this wiring on premium sound cars. IF you have a fader in the dash, this MAY work: you need to unwrap about 8" of fader harness to see if you have 4 pairs of speaker wires, as some cars have only 6 wires, not 4 pairs (8 total) so if this chart does not apply PERFECTLY to your car, don't use it.

Quick disclaimer: this is not idiot proof. You mess it up, don't whine at me, I do not care.

If this saves you countless hours of hassle or you are just feeling generous, feel free to paypal me a tip. Add "@gmail.com" to Stereoinstaller1 and I promise to only use the money for projects on my car.


OK, here is the info.

Obviously, what you do here is simple: connect the "deck" wire to the "dash" wire, then back at the trunk, connect that "dash" wire to the "speaker" wire.

This is not rocket surgery, boys. Get it done.

(AMP REM) Blue/White--------White (this is the one in the same harness as the speakers)

Luke

and this

for what it's worth, every E30 i've wired the two white wires were connected to each other and went out to a single white wire for the stock deck. apply 12v to each until your antenna moves would be my guess :)

I actually have Luke's post printed (in color) but this is a non premium car with no amp so I'm cross checking since I did not see anywhere the whites would connect. This is not 2 whites but rather one w a pig.

Are you thinking they are prewires for,premium sound and are thus spares ?

Antenna

I had missed the small terminal on the radio that confirms this. The large terminal is for the non existent amp

Thanks

Haha I just ran I to this. I just left it capped off. My antenna doesn't go up and down anyways so I guess that I did the right thing
