In your attached picture, the relay is mounted upside down.
Normally the single hole mounting tab goes at bottom, while the three
hole mounting tab goes at top, and #1 terminal will be at top
right.<br><br>
The cover appears to be right way around, like it was never
removed. If you flip the unit over with single hole mount at
bottom, then the cover will also be right side up with terminals 1 and 5
at top.<br><br>
Reason for your electrical confusion is as shown in the picture the wires
are on the wrong termainal numbers. See correct wiring diagram
here:<br>

</a>And there are NINE electrical connections. The shell of the
relay has to be grounded on the body of the car for the relays to
click. You may need to scrape a little paint off of the rear side
of the firewall to make ground connection through one of the
screws.<br><br>

I am just really confused. when I test this, and I have a used one
that a vendor says tested good, I find that terminals 5 and 1 (see
Barney’s webpage) connect to ground when I use a continuity tester.
On the workbench terminals 1 and 5 show connection to the casing, which I
am pretty sure is supposed to be grounded.<br>
<br>
Can someone explain to me why this is right? I really want to make
sure I don’t have an errant ground. <br>
