A chassis wiring diagram will show any connection that involves both systems. Does your owners manual describe which systems are protected by each fuse? That could be a place to start the troubleshooting.
It could just be a bad ground. There are a lot of places to look for one. The engine to body ground was a good one on GM and Toyota cars. I never had any luck on other makes. I had a cable with alligator clips and i would connect it to the engine and a fender bolt. Problems would go away and then I would clean up the regular grounding point or find the broken wire.
