Where this plugs into loose wire next to engine

Hello, Dave here, contributing to RepairPal and providing expert advice since 2010. So sorry, no way to share a photo in this forum. And, it kind of goes beyond what advice we are able to offer, as we cannot diagnose and troubleshoot specific wiring issues. To do so would be highly speculative and not very helpful - so it is really best that you reach out to a shop near you for guidance. The benefit is that you have a first hand expert on hand who will be able to observe the wiring in question and have a sense of where it may go, besides having the resources of workshop manuals and wiring diagrams to assist. So - below there is links to find a shop near you! https://repairpal.com/auto-repair-near-me Click the link or call us at 877-913-1554. We'll gladly find you a certified RepairPal shop in your area.
