I'm in the process of doing the manual high idle mod on my lly and am stuck at tryiing to get the bottom plug off the ecm. Which way does it come off. I undid the gray plastic lever and thinking it should pull right off but it doesn't. Also, in the kit I bought, I just received a green wire with a end crimped on it. Is this all I need? I thought a pin was supposed to come with also. I'm confusing myself the more I type. Ha ha. You gotta love it. A construction worker working on engines.
