Anyone know what the un-labeled white brick thing is that fastens onto the ignition coil?
Has electrical contacts so it's gotta be doin' something.
I think it's a ballast resistor but the FSM electrical manual only calls it "ignition coil"
Anyone know of a replacement option? OEM or improvised, I care not.

You should probly put the year, make, and model

It's either a capacitor or switch. How is it wired? A capacitor would absorb some current when the primary collapses. A switch would be controlled by the ECU and turn the coil primary on/off for secondary voltage.

![[Linked Image]](http://i.imgur.com/dIT1HL5.jpg) On the flipside one could prolly figure out the proper wiring that goes all around there. It can get pretty confusing with it all off.

That's the ballast resistor. Google all it does, but the big thing is that it helps your coil last. You should run it unless you install a coil that specifically says you can do without it.

It drops the voltage st the coil in ign. run to about 6v. In ign. start the coil voltage is 12v. A stock Starion coil (a tad hotter), or an Accel Super Coil work well. Move the wire on the bottom of the dropping resistor to the coil +. Discard the resistor.
