Electrical relays
 

This is the closest forum for the question I have. I've installed a Viper radiator fan in a C5 but I need to change my relay set-up; I've tried searching for info on-line, but no luck so far.

I'm using the Vettes wires for the 2 fans as trigger switches for the Vipers 2 speed fan. The first fan triggers the low speed and the second fan triggers the high speed. The problem is that the first fan's wire stays hot when the second fan wire kicks on; I need the first trigger to kick off as the second trigger goes hot. Is there a relay for this? I'd probably need a 60amp, 5 position relay.
