My car is currently having a Vortech sc installed. I am going with a Greddy Emanage instead of the split second box. My installer called Greddy for a wiring diagram for the ingnition harness and they told him not to install it because it burns coils. I have read other posts saying all you need to fix this is diodes, but I need wiring diagram. Does any have a diagram? Please post it or email it to me at jguzman@carnival.com
