Uhf and stereo wiring gu4

[Limmy]

Hi guys

2005 GU4

Need some advice
Taking out the stocky double din stereo .


I want to install my UHF radio and aftermarket head unit . I want to run to to direct power and not the acc .

1. Can I share the same RED wire ( constant power ) with the aftermarket headunit ?
2. Which is best place to run earth wire?
3. I've read somewhere I may need to get antenna extention. is this true
4. $_57.jpgthis is my headunit . Theres couple of harnesses on ebay , ive seen a few in autobarn ( Aeropro brand ) . Are they perfect fit ?

thanks guys

Not sure what you mean by sharing the red wire, you cannot use it for the UHF, run the power for that back to the battery.
Run the earth wire to an earth point close to the battery.
You will need a antenna adaptor like this- http://www.ebay.com.au/itm/like/150884143623?limghlpsr=true&hlpv=2&ops=true&viphx= 1&hlpht=true&lpid=107
You should be able to get a wiring adaptor that will do the job, just get one that says it adapts from Nissan Patrol to what ever plugs the new stereo has, possibly ISO.

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.

if it was me id be keeping them both on separate power feed also so to make sure you get no possible interference between the two

Can if you want to but it won't necessarily do anything unless you run from a seperate source (2nd Bat/DCDC supply/Power Filter/etc) otherwise all power is common anyway.
Happily admit that I run legal power CB off the Ciggy plug 99% of the time tho.
If you have a device putting interference back onto the supply it will be on all the 12 volt supply and then you need a power filter.

If you have RF interference or an earth loop (both of which can be a cast iron bitch to fix) then it becomes a PIA to find and moving the power can appear to fix the issue

Either way no biggee...

Yep mine are off different batteries

What is difference from Legal and illegal power cb ?

CB is licenced to 5w maximum TX power, some people get commercial radios and program CB frequencies in and run 25w TX power.
It is a dumb thing to do as you will transmit further but the other radio you are talking to you will probably be at 5w and not be able to talk back to you.

[megatexture]

5 watt is legal and there is a commercial strength that requires a licencei think that is like 25watt? i think but if you buy from china you could get a 50watt
