After my head gasket/stud install over a year ago, I had a problem with my grid heaters. I'm running the Banks Twin ram intake with the split grid heaters. When the truck was running, it was smoking the wire that goes into the grid on the front heater. As a temporary fix (because I hadn't driven my truck for 3 months), I pulled the relay off the firewall (the one next to the fuel shutoff selenoid relay), and lost it. I'm getting sick of having to plug my truck in all the time, so I'd like to replace the relay and fix the problem. My question is, is this relay the same as the shutoff selenoid relay, or is it different. I can only imagine how much the dealer is going to want for this and I know Foster's sells the fuel shutoff relay for a reasonable price. Any help here guys? Thanks!

You can use a older ford starter relay. Also, I noticed Napa sells a similar one for snowplows.

 

The relays on the firewall are the fuel shutdown relay and the fuel heater relay. The grid heater relays are mounted on the driver's side frame rail kind of just aft of the battery.

If you need to replace the relays, you can use these. They will last much longer and you can use the stock mounts simply by wrapping the tabs around the old mounts.
