[Mgs] Blinker Relay

[Barney Gaylord]

Dave,

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.

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.

Reason for your electrical confusion is as shown in the picture the 
wires are on the wrong termainal numbers.  See correct wiring diagram here:

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.
