1G 1990 to 91-94 throttle body swap

[KyDSM]

Ok so I'm doing a 90 to 91-94 throttle body swap on my GSX. I was following the write up on here on how to do it, but I'm having a issue with the wiring. My 90 tps only has 3 wires coming from it but also a wire coming from the plug connector for the throttle stopper. And the tps in the 91-94 throttle I believe to have a tps from a 2g or it at least has the plug from a 2g. The write up says the 90 tps wires and 91-94 tps wires will be:

90 TPS wires:

1 Green (IPS)
2 Green/Black (TPS Ground)
3 Green/Red (TPS +5 Power)
4 Green/White (TPS Output)

And the 91-94 wires:

1 Green/Red (TPS +5 Power)
2 Green/White (TPS Output)
3 NC (IPS on 2G sensors)
4 Green/Black (TPS Ground)

I only have Green/Black wire, Green/Red wire, and Green/White wire on the 90 TPS. On the 91-94 TPS I have Green/Yellow wire, Brown/Red wire, Yellow/Red wire, and Black wire which I believe are 2g wires. But I'm positive its a 91-94 throttle body. Would a 2g TPS work with this swap and if so how do I go about doing the wiring since I only have 3 wires coming from my TPS and different color wires coming from the other TPS. Thanks for the help.

Here is the write up I was following.

If you are using the 2g pigtail to the 90 harness just connect each wire to the pin corresponding to the matching color on the 91 plug diagram or use the following diagram for a 2G TPS connector to match the signals.

1 - Green/Yellow (TPS +5V) to Green / Red (TPS + 5V)
2 - Brown / Red (TPS Signal) to Green / White (TPS Signal)
3 - Yellow / Red (IPS Signal) to Green (IPS Signal), only if using a 2G TPS , otherwise do not connect
4 - Black (TPS Ground) to Green / Black (Signal ground)

If using a 1G TPS you should connect your Green wire from the harness directly to the single wire going to the IPS (I would personally use the 2G TPS if available for a cleaner look and durability, the IPS wire always breaks up for some reason).
