I need to set the base idle after doing some intake cleaning. I see two unused connectors between the battery and passenger side strut tower. I see in the FAQ's that the connector that needs to be grounded is a blue/white wire, but I am a little colour blind and I want to make sure I ground the correct connector. What does the connector look like, is it closer to the battery or firewall, and are there two connections in the same plug?
Also, I just changed the cap/rotor, and it is running smoother. I just noticed this morning that it is hard to start cold, need to crank it for 30 seconds before it catches. It ran fine after, and started very well when warmed up. Before I go through the FAQ's, does anyone have a hint to where I should look? Anything I may have inadvertantly done while changing the cap and rotor?

Thanks
