Sup guys...updates are slow but forthcoming. =) I promisse to have pics as everything gets rolling as soon as i get my parts.
I was pondering the issue of audio input. Since there are no aftermarket product that will give you aux input for this car ( unless you want to lose XM) there are 2 solutions that can be easily implemented.
1- Tap into the XM unit using a 4PDT relay ( 4 relay contacts ) for L+ L- and R+ and R-. All you need then is to power on the relay by a switch to go from XM to PC audio.
Cost is like $12 for a 4pdt relay or you can use 2 DPDT relays.
2- Tap into the audio going into the amplifier if you have a 5.1 sound card. Then you will be bypassing all radio control functions ( volume mostly) which you can just use PC to control anyway. This would require 9 wires to be connected. Amplifier inputs from the radio are 3 wires (Left+, Right+, common) for Front and 3 more for Rear speakers. And 3 wires for Subwoofer and Center ( + Center, + Subwoofer, common).
This would need two 4PDT relays and 1 SPDT relay all connected together and a switch button of course to toggle between radio and PC input.
Sounds kind of crazy to use that many relays but I don't see another way of doing this. Right now I will go for tapping into the XM unit and see how that works and keep everyone updated.
Now the HVAC LCD fits very nicely on the lower compartment. I bough a piece of smoked plexiglass to cut to shape and cover the front. Just to make it look more stock I got a piece of carbon fiber vinyl (sticker type) to put on top of it and cut the rectangles for the display.
I just made a switch box with the buttons to control the xenarc and the switches for audio and disabling the power to the PC ( whenever I valet my car, etc...).
This weekened i'll probably take a look at how I will be wiring everything to the trunk.
Any of you guys looked into this yet?
On a side note... I also bought this:
Which just looks AWESOME and not to say that it has a blue light to match the interior of the TL perfectly. It looks EXACLY like the big knobs on the factory radio! I'll figure out a place for it when its all done.
Sorry for the long post =)
