I’m trying to install subs in my vehicle, more specifically I’m trying to install a line output converter at the moment, and I can’t find a wiring diagram anywhere for the radio.

It looks like there are 2 different systems used in that vehicle. The base level has just the 4 speakers and tweeters up front while the upgrade uses an amplifier with surround sound and a subwoofer built in. The attached are both of them. It looks like you could add the converter to the rear speakers in the 4 speaker system easily. The other system you would just as the new parts in place of the OE subwoofer.
