1. Yes, UHF draws less than 1 amp on transmit and bugger all power on recieve but coming off the cig lighter is better. Disregard if you are using a high power CB (illegal but many do, mine will do up to 35 watts RF power) and run a dedicated feed
2. When you pull the head unit out there are several spots you can earth too including the screws that hold the brackets into the dash
3. For what the Head Unit or the CB?
I've not had to use an extension on either but you can break into the Nissan factory antenna feed over near the pax footwell so maybe someone means that instead of buying a diversity adapter
4. I keep getting the part numbers mixed up for Aerpro so won't mention them here but...
The Aerpro "Nissan Patrol to Iso adapter 1985 onwards" fits the MQ's, early GU wagons and all GU Utes until 2000 something. It has one plug on the Nissan end
The Aerpro "Nissan Patrol to Iso adapter 1995 onwards" fits all Wagons and most late model Utes depending on the factory options and for some reason a few earlier than '95 wagons. It has two plugs on the Nissan end.
The Aerpro "Nissan Patrol Diversity Antenna Adapter" is needed for any Wagons (don't know about Utes) with the dual antennas (mast in the guard and copper in teh rear LH window). The other alternative is to find the junction in the pax footwell and disconnect the mast antenna there and run it to your new head unit.
If you don't have a diversity antenna system then the antenna lead will plug straight in to your head unit.
If you have a proprietary head unit Aerpro make adapters for "Head Unit to Iso" that will then plug into your "Patrol to Iso"
Max cost if you need all three adapters (which you usually don't) is less than $40
You may need to connect the "adapter cable" earth to the vehicle earth. Just check if the black wires line up in the plugs. If they don't you need the extra earth.
