...not sure what your options are on a 2003 Mk1 C70 - which is based on the P1 S70/V70 platform.

If there is a Volvo trailer module available - then that is usually the most effective way to go. If not then a generic relay/wiring kit might be your only option.

I hope you don't need to do much reversing as the C70 is high arsed and typically poor rear visibility - much worse with the hood up. Still a stunning looking vehicle event by todays standards though.
