240sx wiring Harness

[NismoTypeX]

Hi, I was wondering if a 91 240sx wiring harness is compatible with my car, all Im useing it for is for the engine bay, I have a 93 that is 5 speed. the harness that i might buy comes off a 91 Automatic..... Will this work??? Im useing my original ECU

it should work there will just be left over Automatic transmission Connectors....right? but it shouldn't affect engine proformance....yes or no....or should I search for a similar topic?

-thanks

I am not sure if they are the same, typicaly there are subtle differences in pin to harness orientation. The only real way to research this is to get a wiring diagram for both years and go through each pin and what it goes to.
