| Whichever prong goes to the brown wire...that should be the ground. |

You can always use your VOM meter to find out. Just take the bulb and measure the resistance between each of the three terminals. The two terminals that have the highes resistance between them are the one that are not the ground. Once you determine which one that is, the lowest resistance is to the high beam terminal.
for example: a
b c this is the bulb's terminal.
a to b is 10 ohms (not actual reading, just to make example easy)
a to c is 5 ohms
b to c is 15 ohms.... the ground is a, the high beam is c and b is then the low beam.
Let me know if you have any questions about this.

| simple version: on mine the middle prong is the ground. |

What I said above is incorrect, Joel and ashman have corrected this and I agree with what they posted.... I should have looked at some headlight plugs I have in my spare parts.... sorry for the misinformation... :oops: |

Might wanna double check that, on every car I've owned it's been the one on the left.
Same as this diagram shows

I think Joel has it right. At least Speedy Jim would agree:

Sorry for the incorrect information earlier. Fixed mine, too. P/O was horrible at wiring things.
(I'm finding out the hard way, of course ](*,) ). |

| If the ground is wrong, one of the beams will be dim. I used trial and error to get it right. |
