I have a 2000 Civic EX that I'm trying to get wired up with an f20b and I have one thing on the harness I'm not sure where it goes. It is a white wire with a red stripe on the engine harness near where it comes out of the firewall of the engine bay. It has a ring terminal on it. I'm guessing it is a ground but I'm not sure where it should be grounded to. Thanks!
