wiring both fans on

searched couldnt really find anything. The DS fan will come on when it should but the PS fan never comes on, all I want to do is wire it so when the DS fan would normally turn on, it turns on both fans. would it be as simple as just cutting the wires of the PS fan and splicing them to the DS fan wires?

Yep, just splice and use connectors and then it will turn on when the other does.

If you want to control when the fans come on you can also splice into the green/white wire at each fan relay and connect a toggle switch to each one. I did this last year and still use the stock fan switch in case I forget to check the temp gauge. So far so good.

im going to leave the DS fan how it is and take the PS fan's power wire and run it to the ignition on the fuse box so it comes on when the car is running
