Full battery voltage in start ONLY. Thru the ballast in run. Go look at the wiring diagram Gomango linked.

Might want to look at the link again. The coil is the one that gets 12V at start only and goes through the resistor at run. Full voltage to the ecu. Does not go through the resistor.

In theory, there is no difference between theory and practice. In practice, there is.
