Well i got the DA rollin last night after the b18b swap. I took it out and about a mile down the road the tempstarted just rollin up fast. i pulled over and noticed my fan wasnt on and my top radiator hose was boiling and spraying steam. i think i got an air pocket.

but my question is. where is a good place to wire my fans into so they come on with my key in the ON position?

or should i just run a toggle to my dash?

 

I don't think your overheating is fan related, either low on coolant or a bad thermostat.

As to wiring your fans, use the original wiring but jump the connector at the fan switch. This will keep the cooling fan on whenever the car is on. If you want the other fan on all the time, jump the oil temp switch that operates the other fan if you want.
