I'm not sure if you Checked out Bill Evans... but he's got some pretty nice stuff if you want to keep it original (not saying you do)
He doesn't make the Dash Harness but he has the parts you'll need if you want to bring the original stuff back. When I reconditioned my Dash harness I bought the connectors and other stuff from him. I've spoken with him a few times and he's been super helpful.
