And I did completely fail to mention but it's an interfire IB 2900.

The bigger problem is that you really need to determine first what caused the resistor to burn out before you replace it, even if and when you do find out the ohm and wattage rating for it. Without a schematic drawing and some experience with electronics troubleshooting, it's normally not the case that a simple resistor change will fix the problem. The more likely outcome will just be that the new resistor will burn up. What will your plan be if and when that more likely thing happens?
