nope you need to make changes to that harness to make it work with the S13 harness dash harness.

you can either look up how to do the harness yourself or pay someone to do it for you. ~200-350 bucks.

wiring harness needs to be modified = not plug and play

there is a wiring step by step that you can search for, or you can simply send it out to a business or member that will do the modifications for you.
