I have a 2015 Renault Traffic 1.6 R9M with a short crank and a main relay short to earth fault code. The vehicle cranks for two or three revolutions the cuts off. - Main relay works correctly. - I have a short to earth on two fuses (F7 & F8) one of which powers the relay. (Test light on battery + and test light lit up on the fuse side to the wiring harness) - If i unplug one of the three ECU connectors i loose the short to earth. Wiring harness is a bit naughty to get at to strip down. Surely this isn't an ECU issue? I have wiggle tested the harness (areas i can get to) with the test light in the fuse and i don't loose the illumination from the test light... Unsure of where to go from here. Any pointers? I have added the initial fault code scan disregard the air mass, fuel and glow plug fault codes i set them. 🙏🏻🙏🏻

I have a 2020 Nissan NV250 with a poorly rear light cluster/wiring. Cluster is available in both aftermarket and dealer so that's no issue but im struggling with the wiring connector Quickco (dealer) dont sell repair connectors and want to sell a full body harness 😬🙄 just wondering if anyone has any contacts for harness connectors or repair looms? Tried eBay, Amazon and local parts suppliers too just trying to do the customer a solid 🙌🏻🙏🏻
