Based on what you're describing it sounds like hyperflashing and errors related to LED lights. If you added an LED light along with the # PP20-702 it would explain that behavior. This is a fairly common issue with newer trucks. You can fix it by adding load resistors like # DI34ZR or using an adapter with built in resistors like # 20142 for a 7-way.
