Hi Everyone - Happy New Year

I am setting up my 120 series Prado and installing the UHF.

Normally I just wire the +ve to the back up the cig lighter/console power plug.

Cant find how to get at either in this sardine can.

Could I ask you experts how do I get to either of these - without dismantling the whole dash?
Alternatively could I ask where you connected your UHF +ve wire to ?

The radio is being mounted on the side of the centre console near the dash.

Many thanks

Grant

Probably best to have an auto sparky do it. It's not hard to do electrically but it is a tricky job pulling the various bits of trim off - and replacing them without damage.
These guys do it all the time.

Will cost you a few dollars - but it's cheaper than wrecking things.

I wired mine up via a fuse block and straight to the deep cycle battery.
My other UHF is wired directly to the main battery.

TO WIRE UP THE BATTERY MONITOR REMOVE THE CENTRE CONSOLE. GEAR KNOBS JUST SCREW OFF AND ALL PLASTIC BITS JUST PULL OFF. THERE IS A GOOD EARTH POINT AT THE BASE OF THE HAND BRAKE. RUN THE RED WIRE THROUGH THE WIRE WALL AT THE DRIVERS FEET AND TO THE AUX. BATTERY POSITIVE.

This is an extract from my DIY daul battery kit. It should help.

Please note that it is not advisable to use the chassis or body for an "earth return" negative connection. With Radio Equipment it is best to run both positive and negative cables direct to the battery or possibly a power take off point as per the 80 series Landcruiser - which is adjacent to the battery.
The cable to the battery should be reasonably thick to compensate for voltage drop and must be fused.
Also, at the radio end, both positive and negative lines should be fused. The reason for this is that a poor negative or ground connection on another appliance may inadvertantly "see" the negative line to the radio via the radios earthed coaxial cable as a good return path. The current drawn may be greater than that of the radio suppy cable may burn it out.
