I need manual fan control?

Can someone tell me how to tap into my dual fans for manual switch. I have looked it over, but would rather have advice from somrone who has done this. Mine is a 92 Z28 with L98. Thanks for any help.

I put 2 switches on mine. One for each fan.
All I did was tap into the ground wire of each relay and run them to the switches and then from the switches to a gound on the chassis.

I did this since the temp switch in the pass side head is bad and it was easier to wire the switches than change the temp switch.
I'll change it eventually though so that the fans will work automatically again.

Thanks for the info ZEPHER, my switch must also be bad because my fans do not seem to be working automatically.

No problem.
I run one fan all the time, just so I don't forget to turn it on if I am not paying attention.
