You have the ignition and the battery confused on the newest relay.

Notice the Position of the vertical and horizontal lines of the relays. Howie is a real stickler for terminal 85 being ground. You used 86 as ground. I corrected that too.

ok cool thanks. also does this even need to be switched by ignition since it will all turn off when the engine cools off or will a relay be on all the time and wear out faster or any thing else like that? thanks

As long as the temp is below the temp of the lowest temp sensor, there will be Zero current draw.  Battery would be better and one less relay.

You could also do without the relay and still have it switch off with the ignition by just connecting the ign switched to the coil of the relays. The main current source can be connected to your fused constant battery source, as it should be. The ignition line will just be used for the relay switching so there's no problem with overdrawing from it.
