91 s13 hatch headlights

[KoukiiSilvia]

Hey guys i had a question, would headlights off a 89-90 240sx fit on my 91 hatch? I feel like the connectors and wires are different. I have to run one stock headlight and the other one being a halogen, so will it hook up directly or will i have to cut the connector and splice it with the other one?

Thanks
