I removed the bulky OEM rectangular bulkhead fitting from the wiring harness because I was stripping out air conditioning wires and connecting some through to the ECM which formerly routed through the 1991 instrument panel and an interior harness.

Now I need a grommet that can fit over or stretch to get the ECM plugs through.

One like this, but new and un-cut looks like it would work. But I can't find a source for a reproduction.
