Is there a wire I can tap power into or do I need to rewire it? I think it would be good to let the fan run all the time as it gets pretty hot under my hood

Connect the blue and black wire going to the temp senEdit:sor on the radiator together. This will make the fan run constant when the key is turned.

Edit: the coolant sensor completes the ground when the coolant hits a certain temp, so just connect the GREEN and BLACK wires going to it to complete ground.

Or you can find the relay under the hood, remove it and make a jumper wire to replace it with. This makes it easier to return to stock if you ever want to.

What radiator are you using?
What type of exhaust manifold are you using?
Do you overheat?

I ask because I don't see a point of leaving the fan on, all the time anyways.

The stock thermostat is designed to open at 192, so that is fine because you need flow in the system. Having the fans on all the time will keep the coolant more in the engine side, more of the time, until you are idling around town and boosting or just stuck in traffic in high ambient temps.
I am using the stock radiator and stock fan with shroud but I would like to know if there is supposed to be a second fan for an AC equipped system, stock (but that is aside).
Do you have a fan shroud in place?
Stock fan or aftermarket fan?

Stock metal fan with metal shroud built in. I removed my ac and it did have a fan

Aha, so I have a fan resistor pack at the front of my radiator support then!
I need to get a picture of what the stock AC fan is supposed to look like. My system is almost complete, I had no idea it was supposed to be there.
I wonder if you add a pusher fan at the front of the radiator, and get a switch with a temperature that triggers the fan relay at lower temps than the stock fan.
Also try to add a cover left and right of the radiator, on the front side, to keep air from escaping around the radiator. So, from the rad to the bumper support area.
Just a few thoughts. No big issue on running the fan on all the time, but if you can get a system working in tandem, it may very well work better.
The best solution however is always a radiator and fan combination that can keep up with the increased power levels.

I have no cooling issues now. I didnt before but I always like to run engines a little cooler. I'll get you a pic of the ac fan.

I was more or less thinking out loud, but thank you for offering to take a picture.
Was the fan mounted next to the fan with a shroud on the driver side, or was it in front of the condensor on the driver side?

I just used a toggle switch with a wire in fuse in my last set up & wired to get power from a power source, & grounded & when ever I wanted fans to turn on I just flip the switch. I plugged in to stock fan switch plug, But i might go back to toggle switch later on .. I like being able to turn fans on when i choice to!

This fan was mounted outward of the radiator bolted to the radiator support.
