Couple Questions about the Stock ECU

hey guys whats up. i just have a few questions about running a stock ecu with the swap that i am doing. i was wondering if i need anything else other than the listed connections to run the stock ecu. so far i have connected....
1a. battery
1b.main relay to fuel injectors
1c. ignition start
1g. igniter
1h. igniter
1j. igniter
1o. map sensor
1u. fuel thermosensor

3a. omp position sensor
3c. o2 sensor
3e. engine coolant temp sensor
3f. throttle position sensor
3g. throttle position sensor
3h. Purge control solenoid valve
3i. throttle position sensor
3l. intake temp sensor
3m. knock sensor

4a.ground
4b. ground
4c. ground
4d. ground
4e. crankshaft position sensor
4g. crankshaft position sensor
4h crankshaft position sensor
4i,j,k,l. metering oil pump
4r. turbo control
4s.charge relief
4t. charge control
4u. wastegate control
4v. turbo precontrol
4w. injector
4x. injector
4y. injector
4z. injector

i was looking on the forum and was seeing people put resistors for the emissions solenoids i have already removed. is that necessary for me since i do not have to worry about smog. i just want to make sure i can run the ecu with the connections i have listed above. if i am missing anything please let me know. i should be trying to fire it up this weekend if all goes well. thanks for all the help

I do not think anyone understands the project you have going here. You mention a "swap". Are you replacing the motor in an FD or are you putting a 13B REW in a different car? Also when you list the connections, are you building your own wiring harness, or is that just what you have connected on the factory harness?
As for the emissions solenoids, if the threads you looked at indicate that you need resistors when removing the emissions controls then you need resistors. The stock ECU needs to be tricked into believing those are still hooked-up or otherwise it will not allow the car to start/run right. You probably also need a few block-off plates (e.g., the EGR valve). But I will defer to the electrical gurus on here.

so i am putting the 13b rew into a bug. i am trying to run the stock ecu. i already blocked off everything. those connections i have listed are the ones i already have connected. i was just asking if there are any other connections needed to make the engine run. as you can see i dont have any of the deleted solenoid wires connected. does that mean i have to still put the resistors in even though i dont have the check engine light?

i guess what im really trying to get at is for instance...pin 1E is an input for air conditioning sensor. do i have to connect this to B+ so that the computer thinks the sensor is off, or this pin doesnt have anything to do with how the engine is running.
or 1M speed sensor. does this affect the ignition system? what about steering pressure sensor. these are just a few i left off because i cant see how they affect the engine management. or what gear the car is in or the clutch depressed. and as far as the resistors go the value is 330 ohm right?
