Anyone know 35' 2005 Cabo wiring well? - Could use help and happy to compensate

[HP12Sea]

Just running into a jam with tracing the Pos & Neg wires from the ECM to where they are picking up the juice. I've tried to look and can trace them to a point but get stymied so just asking if anyone knows an expert in this boat's wiring who can help.

Happy to get an email to discuss terms further.

Thank you,

J
