Hello everyone, new to the forums, but have been interested in these cars for a long time. I'm pretty excited because I'm getting a 98 grand prix gtp from one of my old friends that we use to cruise around in my first couple of college years after high school. I'm getting it for a good price because some rats got into the wiring.

My question is what size is the wiring going into the PCM and the fuse box? It looks to be the same size for both, just some of the ends near the PCM and fuse box are chewed off. Also, where can I get this type of wiring?

Would it be better just to get new harnesses? They appear to be hard to find and costly so I'm guessing no. Thank you in advance.
