Which harness/ECU/distributor for my swap?

[Rsporty]

I've got a '93 DX hatch.
I'm swapping in a '99 Ls B18.
I got it from a guy who, supposedly, already converted all the wiring to go into HIS '93 DX, with the DX ECU, but changed his mind and went K swap.
It doesn't come with an ECU and I'm not sure I trust his wiring.
I still have my '93 DX engine harness, ECU and distributor, as well as a '95 Integra Ls ECU and distributor.

My questions are,
Can I use my '93 DX harness on the '99 Ls B18?
If I can use my DX harness, which ECU and distributor should I use?
Are there any other parts I should get from the '95 Ls?
Are there any other modifications I need to do to make this all work?

Thanks for reading this and any help would be greatly appreciated.

Can I use my '93 DX harness on the '99 Ls B18? -- yes, it will need some modification but nothing crazy (or if you can get the harness off the 95 get that instead)
If I can use my DX harness, which ECU and distributor should I use? -- use the 95 LS equipment
Are there any other parts I should get from the '95 Ls? -- the harness if you can get it, the shift linkage, the mounts, axles, injectors, alternator... thats all i can think of right now
Are there any other modifications I need to do to make this all work? -- probably
