Is there a thread or faq for what each plug goes to? I can't figure out for the life of me what one wire the plug that sits next to the connector for the coil packs. This is wiring for a 90 chassis. If there is no connector thread and you know I would be most greatfull if you imparted that knowledge in this thread.

Yeah it is. I figured it out when I was driving. Thanks!
