is there some reason one cannot simply make a couple of jumpers? from
what you've described, you have removed a relay.

unless you must replace it, you now have access to the terminals and
could simply make two jumpers connecting the wires. for a really
elegant solution, cannibalize the relay and use the base as the wiring
platform. once you've rewired it, plug it back in.

I'd want to do this versus cutting the harness. it makes the fix reversible.
