So, todays progress;
Refitted OE rear speakers, removed Recaro's & loom, removed stereo, Origin B2 and autdim mirror.
Refitted original front seats,
fitted audio remote, constructed replacement phone loom for 6000 stereo, refitted 6000 stereo.
To fit the remote, I used a remote and middle audio plug from a 2001-2003 Mondeo. These use the same stereo as the Puma, but also use the middle socket on the back for the remote and the VSS (in case you want to activate the AVC). I decided I wasn't going to both tapping into the VSS, so decided to relocate this wire to pin 8 and use it for the phone mute instead. To do this, I firstly released the clips at each side, and removed the cover;
Then pushe the VSS wire out and replaced it into pin 8 (shown in pin 7, by mistake);
Next, replace the red cover.
So now you have a plug wired for the remote and the audio mute. Of course if you aren't going to bother fitting a phone kit, that stage was irrelevant!
The remote works by resistance, you literally just need to join the two wires from the new plug to the two wires on the back of the remote.
Next step is mounting the remote, so firstly remove your lower steering column shroud (5 x philips screws);
Work out where you want to mount the remote, if I was doing it again, I would put it a bit further forward than I have. Next job is to chop the protruding arm off the back of the remote, you won't need it.
Once I had decided where to mount the remote, I used a 10mm wood drill bit to make a hole for the socket, then using a smaller bit (3mm?) drilled holes for two self tapping screws to mount the remote to the steering column shroud. I made the mistake of using my cordless to mount the remote, this isn't a good idea as if you get it too tight, the buttons won't work.
I used around 750mm of cable to go from the steering column to the audio area, once you have mounted the remote to the shroud, extend the plug from the remote by around 750mm, run the wiring to the audio area and refit the shroud.
Next join these wires to the new plug, and refit the stereo, job done!
I think it is great, a well worthwhile modification for anyone who wants to retain the OE stereo, or even for people who have an aftermarket stereo with an input for a remote. I would have done it earlier, but my Kenwood could only use an IR remote.
