Replacement 4-Way Recommendation for Euro Truck that Runs on 24 Volt System

Question:

I have a 24v European truck with a very corroded 7 pin round Euro vehicle side connector that needs to be replaced. The existing wiring has been confirmed as functional. Can I use the existing wiring with a new 4 pin flat vehicle side connector? If so, what 4 pin connector will I need that is rated for 24v? Please advise. Thank you!
