The Red wire goes from the 12 volt input plastic block---to the Thermal Disc on the Flue cover--then the Flame thermal fuse wire goes on the other side of that disc to J4 of the Control board. Originally, J4 was connected direct to the Positive input plastic block by a short 6 inch wire. Now it goes across to the Flue cover and then thru the Temp disc then the Flame Diode and then to J4.

PS, I still think your original board is good, you do not understand the Red wires and the Flame and Thermal disc. If I am correct, your new board will not fire up.
