I hooked up the only orange wire I can find coming out of the mcu and I found two purple wires and I cut the one I thought was coming out of the mcu spliced them together and tried to start the car after turning the key the third time it sounded like the starter locked up on the flex plate. well f*@k I cut the wrong purple wire checked it and tried the other one same thing. put it back the way it was and it started easily. tried it again and then found out I have no spark. the orange wire seems to be a thicker gauge. what thew heck I'm I doing wrong in my head this is a 15 minuet job tops but I have been at this for a while. I don't know what is going on but I and close to buying a HEI and saying the heck with this crap. some one save me some money and tell me exactly why I shouldn't be working on cars because what I am missing is so obvious.
