So...

I was thinking about maybe upgrading my amp and installing a sub, for a bit more kick.

So I take out my boot lining to see what I have to work with... *cue comical sound* There's not even an amp there to begin with, just a couple of cables with copious amounts of wires leading nowhere!

So I searched, like a good boy, for the wiring diagrams and colours of wires etc and came up with nothing, everyone else's plugs seem to be very different to mine and I have an extra couple of plugs (I think they may be for a CD changer though). It seems every other bimmer is different to mine.

I have a 1998 E46 323i, with 6 speaker (two tweeters, two in the front door and two on the rear parcel shelf).

Has anyone seen these before and have wiring diagrams or guides!?!?!?

This was in a blue lever type plug.

This was in a white lever type plug

Don't know what that's for. I thought maybe the aerial... made no difference.

CD changer? :dunno:





Thanks!

It's hard to tell without the lever housings.

The big white one could be the amplifier, but it would be used with a second large Power MQS plug in the same lever mechanism for the high current stuff.

Blue and white 18 pins are for the TV tuner.

I think Sirius is blue 18 but we don't get that in the UK so I'm not sure. Could also be an SES socket on the phone harness.

Antenna is either TV, FM or phone.

Last one is CDC.

I think perhaps your car had factory nav and that was removed? Is there a 17 or 40 pin plug with an extension up to the new radio? Any chance of some zoomed out pics with all the levers back on?

Hmmm I'm pretty sure it never had factory nav, it had a BMW reverse cassette deck in it when I bought it. But it could be pre-wired for it?

From what I've seen, the amp plug is a black lever thing with two inserts in it? Mine are nothing like that, so I was thinking it could be similar to the E36 system?

Here's some more pics, I hope they help!

Definitely CDC are the two small plugs.

The white one I dunno, as the blue one is too long to be TV. A white and blue pair of 18 pins is TV. A blue and violet pair of 18 is the GPS drive.

Therefore the blue one is probably SES (voice module).

Dig around more. Is there a bundled 54 pin MQS or 25 pin DB25 connector and a couple of purple and cream FAKRA or mini UHF taped up in a loom? The sharkfin suggests you are prewired for pone, so find those phone connections.

For a sat nav car the FM tuner/amp goes in the boot, therefore the 17 or 40 pin power/speakers and the FM connections would also be in the boot, and a custom extension fitted to return those to the radio/cassette up front.

As much as I'd hate to admit it, the shark fin just sits over the conneection for the stubby aerial.

It is factory fitted sharkfin containing a GSM antenna no?


EDit, not on a 1998 no it won't be.

You probably have a DB25 phone connector somewhere, in the same bundle as the mini UHF in post 1, pic 5 probably.

Ok so I pulled out my boot lining to dig around a bit. I did find an extra plug, bundled in with the lever plugs.

I also checked the wiring colours against when I changes my head unit, some of the colours match up (like the white with red stripe and yellow dots) but the actual speaker wire colours are no where to bed found. Does this mean it couldn't be for an amp?

I snapped a few quick picks of the other plug.

The lever plugs with the newly found plug.

CDC plugs

EDIT: Also there was no FAKRA or 54 pin MQS.

The small three pin is possible the mic. The red/white/yellow is iBus. Every module will have it.

What about the coaxial antenna cable? Where does it go? Looks like it has an extension or something. I assume it's in the same bundle as the blue and white connector?

have a look under the read passenger ashtray for the BT antenna connector and also under the armrest in the same area for a black 12 pin MQS. It's unusual that you have a phone of such an early car.

I still think there is a DB25 to be found.
