KA24DE Major Wiring Problems..Help

[twcustoms]

I am confused as hell about the wiring on my swap and I have searched and searched and have not had much luck finding info that i need.

I have a 90 240sx auto...I swapped in a 95' 24de.
I have the following harnesses...1990 body, dash/rear interior and engine. 1995 body, dash (with all of the little computer boxes and relays), and engine and ECU.

Here are my problems. The 95 is obd2. The body harness obviously will not run the flip headlights, and the plugs to the steering column (ignition, wipers, lights, etc..) are different. There is one plug that is the same on the ignition. If I use the 90 dash harness, it will not connect to the ecu portion of the engine harness so I am lacking communication between the two. I lack the rear harness since the 95 is a two part and the 90 is a one part so I have no fuel pump. I can get the motor to turn over, but there is no spark and obviously no fuel.

Please help me with this, I can't figure out which harnesses to use and what to splice and I do not want to have to track down a s13 harness, intake manifold and all that good stuff because I have already spent a good deal of money for what I have. Sorry for the long post but can someone please help or give me a link to the info. Thanks.
