Ls3 valley cover oil pressure sensors to ls1 harness?

Hi guys have an ls3 valley cover on an lsx block. The oil pressure sending unit does not directly connect to the ls1 harness the connector is different. Does anyone know what I should do? Is there an adapter? Or do I just cut and splice? Please let me know

Thanks!

the ls3 valley cover looks to have a 1/2" threaded hole(or whatever the threads are) in the cover itself(covers where the original ls1 cover doesn't) and the ls1 OPS hole looks to be 1/4"npt or so.

I'm gunna look at it more in depth this evening and try to figure something out.
