This is a HACK of the STOCK SC radios which allows you to install an AUX input, WITHOUT the LOSS of the CD CHANGER port, and only costs a few pence.
HOW>
well, it taps into the outputs from the TAPE DECK. easy!
ok, so today, i carried out this hack on my 2 Stock heads
one is the Sc800, the other the 801
the method is the same for both. It can be done on the 805, but I will post that later
here is how to do it
first, remove the LOWER panel from the unit
look at the rear end, for a bank of pins in a straight line
count the pins upwards, and find 4, and 5, these are the L+R we need
once you find the L+R you need to trace the route from there to two components, labelled 102.
we need to attatch two 10uf capacitors to the OUTPUTs of these.
make sure you solder the NEGATIVE side of the capacitor to these points
we then feed in the cable we want, through the vents on the rear plate. I chose the FEMALE PHONO, as it gives the option of using PHONO or 3.5mm jack [with lead]
we need to attatch our main cable from each to the POSTIVE ends of the capacitors
this pictue is not too clear, but what we need to do is combine the two EARTH shield wires from the cables, then choose an earth. I used a main board earth which attatches to the chassis as shown
now that is all done, we simply tidy it all up, making sure the cables are all shielded correctly fro the main board.
now simply replace the bottom cover, and you have a modded unit
Now, to get this HACK to work, we need to FOOL the unit into thinking there is a TAPE installed, so it will allow us to select TAPE
the way I still do it, is once you have the unit connected in the car, remove the TOP COVER and manually close the cassette cage. The unit will think there is a cassette in, but there is not. It works on both of my units. Just do not press EJECT or you will have to remove the unit to do it again
you can use a BLANK CASSETTE, or one of those mp3 convertors, and just remove the cable, but I find doing it my way works great, as long as I do not press eject
to hack this, simply remove the top lid with the 2 screws at the rear
inside, on the right side of the tape deck, you will see 3 wires shown. RED WHITE and BLACK
these are the LEFT RIGHT and GROUND outputs from the cassette
we simply need to use our hack as above, and attatch our 10uf capacitors to these wires, simples!
