HEI module Testing

I have been trying to get the mod to work but its isnt working, i have tried it several ways, and still no go.

Is there a ways of hooking this up to test the thing ? if so please let me know. And if anyone has any more info on how to actually wire this up....Thanks.

This is what i have so far
W to + on pickup
G to - on pickup
C to - on coil
B to + on coil as well as 12v source.

If someone could draw a diagram...that would be great. ( i know it sounds really easy but im not able to)

Do you have the module grounded?

HEI module itself needs to have a good ground or the module will go bad, or not work. Silicone Di-electric between the module and its ground works wonders.

Certainly check the ground, if it's installed then pull a plug and leave it out while turning over the car if it doesn't spark then mess with the ground, an HEI should have a ground strap the runs from a mounting screw to the ground on the harness and if it's anywhere near loose it won't start.
