220k resistor is wired as follows, one pin from speaker to chassis loom has a wire rail attached, then the 220k is next on the rail, from that the 220k is connected to a 0.1 uf yellow cap which links into a wire that connects to pin4 in one direction, and chassis in the other.

500ohms is the answer for pin 5
