Electric question

[samsx]

I just got my electric rad fan and I want to plug it with a switch inside the car. I want to know what gage of wire, and wich fuse should I use, and also, where is the best pace to take my power source.

Also, I bought a oil pressure gauge and I not really sure of the place I need to put the sensor.. Can I just removed the stock sensor and plug all the wires on the new one, or can I just plug my gage on the stock sensor ( probably not I think ...)?

It depends on how much maximum current you expect to pull. Most electronic fans pull 20-50A. Check with your fan manufacturer. Use that fuse or a lower number fuse.

For 20A, I recommend 12 AWG or bigger. For 50A, I recommend 8 AWG or bigger.

Nissan isn't as nice as Honda in that the factory doesn't give you any provision to tap for power. On Hondas, there are a bunch of spare terminals in the fusebox that are already prewired and fused. You just have to run a spade terminal from the fusebox.

I recommend tapping power straight from the battery.

Do a quick search. There are at least 5 efan wiring threads.

If you can get the gauge to fit, this is best because the factory oil pressure gaug is just an on/off switch for the oil light. Others may have better ideas on where to mount the sensr.

It depends on the gauge. If your gauge is just a light, then yes. Otherwise, I highly doubt you can calibrate a gauge to work with the stock sensor.

i run altima fans on a 30A circuit (#10awg). used to have them switched on a 5a radioshack switch that never burnt out lol, now they are on a tstat controller

Just because you get away with it for a while doesn't mean it's safe. 5 out of 6 times you'll win at Russian roullette, but this is a game I don't want to play.

You clearly know that it's not good to use a 5A switch to pull 30A without a relay.

lol yes of course. im an electrician by trade

What's the difference between an electrician and an electrical engineer?

I'm asking because I minored in EE. What does each know that the other doesn't know?

I focused mostly on computers and digital logic.

engineers design what i install i do mostly residential stuff though so it's a pretty small scale comparatively

what I really want to know it'S if I can replaced the pressure sensor with the new one, or if I need to keep the 2?

Yes you can use the stock oil pressure sender location. all the stock one does is trip the dummy light. throw that shit right in the garbage. but unless youre using a jdm gauge you will need an adapter to 3/8npt or whatever the thread is (cant remember off hand) or cross thread the new sender in (i know reputable people in the business that actually do that lol)
