Hey guys I am finally putting the motor back in my Mach 1 ( Ford Racing 5.0 Boss Block, Stock Mach 1 heads, Custom Cams etc) , I am 99.9% done however there is a sensor or capacitor off the cylinder heads it appears? Its one wire/steel cap and comes off bracket which bolts to head. There is one on the passenger side rear head by coolant line and heater core and another on front driver side, I have never noticed this or seen this before? Do any of you guys have any idea what it is? let me know what you guys think
