Hi Vince

On the driver side of the fire wall you will find cables going through a rubber grummet I managed to get our positive & negative cables through with enough
room for the coax aerial.

I then got all the cables under the dash and hid them under the gear stick consul
between the bucket seats, we fastened the radio to the back of the centre consul,
it looks like a factory installation. cant see any cables all hidden.

Cheers
Daza

As mentioned above use the big groumet where the main wiring loom enters the cab through the firewall just below the brake master cyl. A bit tricky to get to, but do be careful you don't damage any of the wiring in the loom as a lot of weird electronic malfunctions have been traced back to damaged wires where this has been used as an access point to the cab for spot light switches etc.
