Adding an electric fan to my mustang and it requires a 75 amp relay to run at high speed. Can I run two parallel 30/40 amp relays in place of the one?

Part Number: PAC-80

The PAC-80 handles 80 amps continuous and 150 amp surges. Perfect for show systems utilizing lighting and motorized enhancements.

Thanks for the reply. I was going to buy a relay like you are showing, but I have a bunch of relays laying around from remote start installs and I'd like to use them up. Plus they are paid for already!

So you need two relays, 2 sets of power feed plus a nice reactive load and lots of on-rush current, I think you're heading for trouble using 2 x smaller relays, I hope Mr Idiot and Mr KP would comment here.
