The ignition circuit should be left alone, nothing added. If something must be added to the ignition circuit then a relay would be prefered. The ignition circuit feeds power to the ignition system and any extra load added to it may cause undesired effects.
The accessories circuit is more adequate and even then, the amount of power the add on controller needs is a factor. To avoid overloading any existing circuit a relay should be used. The relay uses a small amount of control current on the solenoid to switch power contacts to added loads.
Bottom line is suggest the use of a relay. Control the relay thru accessories circuit and a fused power wire from the battery is switched for added loads.

Brake lights not working there is power on the brake switch only when the key is on

How many wires are on that switch? The brake light wire will be hot at all times, key on or off. Have you checked the fuse? Has any re-wiring work been done recently? Anything installed requiring work done under the dash?
A plain brake switch, with no cruise control or any other wire, will only have two wires at the switch connector, one hot wire from the fuse panel, and the other wire going to the brake lights.

I want to install a rear heater in a safari, how do i run the power, and hoses, if any, to and from the battery/heater?

You could just Tee into the heater hoses in front and run a hot wire from the accessory side of the key switch. The blower would need some sort of fuse. Factory systems are wired into the front control.

I have 86 celibrity, electric fan will not work. if i take test light and check where the relay switch is, red wire hot and light comes on, if i turn on ing. switch and take test light to green wire (2nd...

What your doing when you touch the test light to that 3rd wire is actually closing the circuit and powering the fan, like the temperature controlled switch should be doing once the engine warms. That sending unit would be screwed into the cooling system where the water can touch it and most likely is in the radiator lower tank or bottom of radiator side tank. Find that sensor and test the wires for power when engine is hot and fan should be on. You could put a toggle switch on it to activate the fan until you get the proper sending unit/sensor.

My dash lights went out and at the same time my running day lights in the back and front went out as well. But all my brake lgihts still work..And i already checkd all my fuses and the in line fuse and...

The fuse that works the tail run lights also powers up the fuse going to the dash lights. That fuse is hot all the time and it goes to the headlight switch the switch can be bad but so can the connection to the switch and the connector to the steering collum. Test light should find two wires hot with the key off and another comes on with the key (turn signals) with the switch on two more wires will go hot (high or low beam and the tail lights) if they don't add power with a jumper wire and see what comes on there are no wires that will hurt any thing by adding power to the switch wires but one of them should turn on the tails and dash oncew you find this wire the switch should turn this wire on too if it doesnt and theres two wires hot with the key off and the switch off then the switch is bad install a new one and it'll work good

Which wire is the factory Acc-ING and which is B+ 2005 nissan Alt

Sounds like you're hooking up an aftermarket stereo. The B+ is for a battery constant-on connection. you can find one with a voltage probe tool (looks like a pointed screw driver with a grounding wire attached... and a light bulb in the hande. You can probe for a b+ connection by connecting the ground clip to a solid grounding point and probe for a wire that is "hot" while the key is off. For the acc wire, find a wire with the key on that is hot, but goes off when the key goes off. There are several posibilities and any will work, as long as your lines to the stereo have a fuse.. Happy probing. k
