So I`ve been talking to the previous owner and He is having the same trouble I am. I asked about the Connections and here is the email response. It does make things a little clearer and also lines up with what nisileighty said about something is missing on the Chassis side.

Email - "you may be running into the same problem i am with the s15, both those harnesses are old wiring specialties harnesses that came off the ebay 240sx groups. i got a diagram from wiring specialties website for mine, that should be the sr20 universal pro harness, but the old version, i think they are then same, however like i said the problem im having and let me know if that s14 is set up the same, there should be existing wiring from factory, (all the ignition wiring) that goes to an ecm (electric control module), the main harness that is plugged into our ecu's is the main engine and trans harness so my issue and i think it may be the same with that is there dosent seem to be anything to connect the ecm to the main engine harness or the ecu. correct me if im wrong but a car needs spark, fuel and air to run, fuel lines are done, all the intake side is done, everything under the hood it done, when you turn the key its getting power its just not sending signal to the engine to give it spark? so find where the ignition wiring ends, if it is in an ecm then look to see if it has a plug in spot on it that nothing is hooked into it,if so send me a pic of it, because maybe there is a harness that goes to the main engine harness (assuming there is an unused clip on the main engine harness inside the cabin) that we dont have or i have sitting in a box here somewhere, so if i know what the connector looks like i can look for something. my ecm does have a place to plug into it but my problem is there is nothing on my main engine harness or ecu to hook it into, sorry for the novel. "

So to me we are both having issues connecting the Engine Harness into the Chassis Harness. As per my last post the Large Skinny Connector is plugged in and I thought it was Re-Pinned but its an Older Model Wiring Specialties Harness so it makes since why it connects. I still have no idea about the Grey and Black plug just down from where my ECU plugs in. Going to hook up the battery today to see if anything lights up.
