Guys
i have a LT1 car that I am installing a Big Stuff 3 package on. I have everything hooked up but no spark. The big stuff gets its signal from the optispark, but there is no where to hook up the coil, and module. So i have hooked 3 of the 4 wires on the module back up, however there is one wire that represents "Ignition Control" that I found off of Shoebox's website. My question is... does that need to be hooked up? if so where? I am really lost on this one. Thanks for the help.

 

Doesn't the Big Stuff ECU have an output for ignition control? That signal would connect to the white wire that goes to pin B of the IC Module.

 

Thanks for the response. I did try that after you posted, nothing yet. I will contact Big Stuff next week and see if they can help me out. Thanks again. If anyone else has something let me know.
