VT commodore stock headunit issues

[Big_Fudge]

Hey guys,

I picked up a VT commodore about a week ago that had a crappy single din headunit. The wiring was so ####ed that it had no constant 12v and all the wires were twist and taped with gaffa tape!!!

Anyway, went to pick and payless this morning amd picked up a stock double din headunit with the wiring pigtails. I soldered and heatshrunk colour to colour. Howwver I have a couple wires leftover. Plus the headunit lights up (dims when headlights are on), however doesnt display anything. I was understanding that once it was switched on it would ask for a secure code??

The following wires are leftover from the headunit plug i got today.
Pin 1 tan
Pin 13 light blue
Pin 14 white.

Leftover from body loom
light brown

Light blue not pictured

Any ideas guys?

I am also understanding that the headunit might be stuffed. Just trying to find out if ive missed something stupid

I suggest that you double check your wiring because something obviously isn't correct. Search further back on the loom to see if you can locate your missing wires.

Fixed.
dodgy ground going to chassis.

Now only to find out why my instrument panel will not illuminate
