anywho. just to get things ready for my swap ( If it ever get's here)Just a few more question to confirm.
1.The Stock KA Driveshaft can be used right?2.I dont need to turn the transmission mounts around right?3.It wont have that down pipe not clearing the steering right.?4.I am going to get my rb20det clip and parts right? Night?:D

This how-to is for 89-90 240SXs that came equipped with SOHC engines. Wiring up a 91-94 DOHC engine should be very similar, but not quite the same. This how-to also assumes that you already have the engine and transmission installed. If you are performing this swap, make sure you have the engine and transmission installed properly.
1) Run the ECU harness into the passenger side of the car, extending the mass air flow sensor, and O2 sensor wires.
2) Locate 2 plugs on the RB20 motor harness. Both being rectangle and one having 6 wires, and the other having 8 wires.
3) After locating these, find the female end of each of these plugs and cut them back about 6-8 inches.
4) Locate 2 oval plugs on the KA chassis harness, one being grey, and the other being brown.
5) After finding these, cut the Black/red wire, and connect it to the Black/red wire on the RB plug that was just cut.
6) On that same plug, cut the Red wire and splice it to the white/black wire on the same RB plug.
7) Going towards the fuse box, there will be a white wire that goes into the box. Cut and strip both ends of it.
8) Splice the white/purple wire from the RB plug into the white wire.
9) Off of the ECU there is a Black/pink wire for the fuel pump, run a wire from the ECU into the engine bay to the black/pink wire from the fuse box.
10) Now there will be a plug with 2 wires in it on the KA chassis harness, one being white and the other being black/yellow. Find the black/white wire on the other RB plug and connect the two.
11) Coming out of the fuse box there will be a plug that contains a small white/red wire. Take that and connect it to the white red wire coming from the RB motor harness by the alternator.
12) Take the thick white/blue wire and run a wire from there to the positive battery terminal; that will charge the battery from the alternator. The way I did mine was I took the RB battery harness and connected it to the battery as well as the KA battery harness, that way it powers the KA harness and the RB harness, same goes for the negative battery cable.
13) Make sure to use the ground for the starter from the KA lower harness
