Oh boy, the dreaded basket of snakes problem. If you look at the wiring diagram, you will see that the ignitor unit has around10 inputs. The heat is caused by excessive current flow which means something upstream may have failed. If this is the case, your new unit will have a very short life expectency. A shop manual, a digital voltmeter and patient methodical checking is called for.
