Hi guys... I was hoping someone here could give me confirmation on getting my tuner to work in car with my empeg. I had my Mk2 installed in my 2006 WRX a few years back. It's worked more or less fine, other than my issue documented here Dim or Turn Off Standby LED?. From the looks of it, the Blue Amp remote wire is plugged into power. I am not an electrician (and now possibly my installer wasn't either), but it appears they have made minced meat of my sled wiring. The Blue Amp Remote wire and Black Ground have been cut from the tuner plug and wired directly into the vehicle. I'd like to use my tuner to interface with a Sony Stalk Remote. Can I just splice the blue and black wires back onto the tuner plug and have this work? Second question... looking at this mess, can anyone see what else is wrong and maybe point me to a solution? Thanks very much... image to follow

If those cut wires were originally from the Tuner Plug, then yes you need to hook them up there to make things work. Check out the Tuner Plug wiring diagram here: Diagram: Key: The blue wire on the right, if that is coming from your Empeg Sled then yes, thats not connected up right. That wire is supposed to be 'Amp Remote' which goes +12V when the Empeg powers up so your amplifier knows to turn on. The yellow wire from the car harness is probably 'Memory' which is the permanent +12V that the Empeg should be powered by. If you have a VW or derivative Memory and Ignition Sense may be swapped over. Note: There are probably two Blue wires from your Tuner. One is supposed to be on the Tuner Plug. The other is hanging free - this one is the Antenna Remote wire which goes +12V when the source is switched to 'Tuner' on the Empeg. Use this for signal boosters and those retractable electric aerials if you need to, else tape it up and tuck it away. Don't mix them up.

Thank you so much for the reply... I have two questions about how to proceed. Just to confirm, the blue and black wires at the top of the first image are indeed from the Tuner Plug. I used a print out of the image you included below from the FAQ to confirm my suspicions. Thanks for including it for completion sake. Question #1: Short term. The empeg works with the current wiring. If I were to splice the blue Amp Remote and the black Ground from the Tuner Plug back into the matching wires from the sled, the Tuner should work? Question #2: Going over the diagram I seem to remember the yellow Memory wire had a black plastic piece that I assume was the "Filter and Fuse" shown in the diagram. That is sadly long gone. If I could find a new wiring harness for the empeg, would this revised diagram I am attaching be the correct way to hook everything up? I'd love to take this information back to the original installer, but they are no longer in the Car Audio business. Again, thank you for taking the time to help!

The diagram you have drawn looks okay to me. I'm curious, where is your yellow cable from the sled connected to? Note: There are probably two Blue wires from your Tuner. I just want to clarify that this probably applies to PCATS tuners only, not the original black Empeg ones. Original tuners don't have that additional blue accessory cable IIRC.

Short term. The empeg works with the current wiring. No it doesn't -- you have previously posted about the standby LED being constantly on or something, which is a definitely sign that something is very wrong with the wiring, and it may destroy your empeg eventually.EDIT: got your post confused with another thread. Ooops! Cheers

Thanks Guys... I'm curious, where is your yellow cable from the sled connected to? I will have to look closer, but it appears it has been cut and thrown away. If I could find another wiring harness I might be able to retrofit it to the current set up. They created a special gauge pod with my sled that I would like to continue to use. I specifically asked them to make no permanent changes to the sled... but I said the exact same thing about the wiring harness. EDIT: got your post confused with another thread. Ooops! That actually sounds like sounds like my thread I linked to in my original post. I would love to fix this aspect of my install, but in the short term I fear I do not have the parts or the know how to do so. If the yellow memory wire is still attached to the sled, is the "Filter & Fuse" part something I can pick up somewhere and easily patch in? I am familiar with the technique of reattaching wires to the sled contacts, but I have no soldering tools or skills.

Clarifying even further: PCATS tuners had a blue wire coming out of them to power a powered antenna. Factory tuners did not have a blue wire coming directly out of the tuner module box iteself, however they included a snap-in extension cable that *did* have the extra blue wire coming out of the extension cable for the powered antenna.

Thanks to everyone for their help. I now have a working tuner and my stalk remote works!
I hope to either find an unscathed sled or wiring harness and fix that standby mode LED issue. For now I am just happy it works and required very little scary electronics work!
I have some questions about optimal stalk remote use, but I will ask those in a dedicated thread.
Thanks again!

Yeah, if your standby LED is staying on all the time, it means that you're somehow *applying* power to the blue amp remote wire instead of letting the empeg use that wire as a signal to turn the amp on and off. Something is wrong with the way the amp remote wire is connected up.

Yes... the LED is lit in the car due to how the installer wired up the sled.
It appears if I can find an equivalent "Fuse and Filter" module to wire to the proper point on the sled, then splice to the yellow wire leading to my car, this will be fixed.
The question remains, what exactly is the "Fuse and Filter" module? Is it a simple in line fuse? Is it something I can pick up/order from a local Radio Shack?

The fuse and filter module will not change the fact that the wiring is wrong (if, in fact, it truly is wrong). Add a fuse and a filter, and now you have an incorrectly-connected wire that is protected by a fuse and is noise filtered.
The fuse and filter module to which you refer is, I *think*, a small box on the yellow (constant power) wire which contains a power-line noise filter and a small fuse. If you don't have any noise problems and the wire is already fuse-protected somewhere upstream, then you don't need it. If you do need those things, then yes, you can get equivalent parts at radio shack.

I have a factory tuner module but no snap-in extension cable. Currently the antenna is activated by the ignition, and up all the time. Is there a work-around for enabling the module itself to activate the antenna without the cable? Or is there a way of getting one? Many thanks. I've snapped an antenna already ...

Yes, you can see if Eutronix or Rob can get you the proper extension cable that includes the correct wire. You could also just do it yourself: add the necessary pin to the connector that plugs into the tuner module and make your own blue antenna remote wire coming off of that pin. I think (not certain, someone needs to back me up here), that there are eight pins on the tuner connector, and seven of them are used on the sled-to-tuner plug. The one remaining pin that is currently unusued on the connector is the one that you want to be the antenna remote wire. If you decide to go the D-I-Y route, don't just hook it up and hope it works. Check the voltage on that pin with a voltmeter as you turn the tuner on and off from the player's front panel. If it behaves accordingly, then you've got the right pin.

Fantastic! Thanks! Yes, based on the wiring diagram, that looks like it backs up my theory. Simply add a pin and a blue wire to the one unused hole on the standard tuner connector. Test its behavior with a voltmeter. The hard part might be finding a pin for that connector, at that point, just call Eutronix anyway and get a proper extension cable.

Test its behavior with a voltmeter. I got hold of another factory tuner and harness. Now I'm getting a voltage from the power antenna wire. It seems that the 12v is there from the word go. Switching on the ignition: 11.62v --> 12.42v Switching on the player: 12.35v Switching on the tuner: 12.31v Switching off Rio: 12.42v Is this the right behaviour? I imagine -- could be wrong -- that the antenna stays down when using the player, and only comes up when the tuner module is selected. Perhaps there's some problem with the power source for the whole set up being via the ignition and not passing through the auxiliaries circuit. I would have thought though, that the tuner would not be giving out 12v when it wasn't in use. Any clues?

Is the slight fluctuation in voltage enough to trigger the power antenna? I can't quite see how the antenna gets the message.

Do you have that wire hooked up? If you're just measuring it with a meter and otherwise open, you're probably just measuring leaking voltage. Try an led and 1K resistor.
