Where is the Primary coil?

[kennydawgg]

ok got a spyder gs 4g64, died on me the other day while I was driving. Checked the fuel, all ok. Moving to spark, I have none. I pulled the coil and checked the resistance, the secondary coils are in speck but the primary is out of whack. I looked through the manual about a dozen times but I can not figure out where it is. I followed the wire and it goes into the firewall. Is it on the ecu somewhere? any help would be awesome

thanks
