Yes, buy new aftermarket. Here's something similar:

There's all kinds. I got black with black wires, you just snip and solder/heat shrink. That's what I prefer, but you can butt splice them in too I suppose. I tried everything cause I was on a time crunch and had to have the car running. Even depinned the original connector but couldn't get any solder to take...now I have extras for when the 3UZ hits 200K and some more inevitably snap. Good luck!
