Well had a bit of spare time today so did some more stuff.....changed the gear selector LED, and then had a brainwave.....I was going thru some of my computer gear yesterday and I found a brand new 5 1/4 inch temperature sensor unit......had a bit of a think and worked out if I soldered a resistor on I could allow 12 volt instead of 5 volt, so hooked it up into the pocket under the stereo.....has 2 temp sensors on it so hooked one up to the AMP and the other to the Stereo itself, so it now monitors the Temps of both units......unfortunately the readout display is green so am off tomorrow to try and find the readouts in blue and will desolder the greens off and put the blues in instead....
yeah I know it's a bit out there, but I'm always doing things differently and like to do things to make my car unique.....Andy

Well wasnt happy with the green display with everything else being blue, and unfortunately I could not change the colour of it.....so decided to change it....cut some black acrylic to size to cover over the pocket face, then installed a volt meter plus 2 switches to operate lights in my boot , for my planned boot install......much better me thinks.....
