I know there have been many threads on this topic. Regardless I would like some input on my train of thought plz.

I have a 1991 B16A PR3 setup. The dash harness is a DX but it was wired into the ecu when i bought the car. No check engine lights. I wanna go obd1. I want to verify that wut im thinking should allow for a plug n play setup ( from the research ive done) or if im just full of crap lol.

So ive gathered that I need or options that will wurk are:

Obd1 distributor TD44U
P30 edu
4 wire o2 sensor
rywire obdo (MPFI) to obd1 conversion package.

Again my question is if these particular items will allow for a plug and play setup from my current setup? TIA for any input.
