I'm digging through my Service Manual and I can't find anything that talks about removing that harness (pulling it back through the firewall). I'm sure it's in there somewhere.
Is it as simple as the main bulkhead connector (C219 I think the connector number is) will pass through the firewall with the grommet removed?
