Bob, mid 90s vintage Ford relays all have the internal diode. When
getting a replacement at the auto store I just look at the diagram on
the thing. Most of the time they try to sell me the cheaper one with
no diode. Then I just ask for the more expensive one and shure enough
they always have the diode. There are 4 or 5 of them and they are all
the same part number. NAPA is a good source, but not RS. They are the
traditional 30a things just like we are all famiuliar with and fit a
1/4" female faston.

I know the answer must be blindingly obvous but it escapes me. Why have a
diode in the first place, doesn't the relay close regardless of which way
the current is flowing?

Voltage spike suppression.
Bob posted a document a few weeks ago about the how and why of spike
suppression. Here is the link.
