Sentra headlight wiring!

{p}Forgive my ignorance here, but I really appreciate any help you guys can give me.  I did search and found some info but Im still confused.  {/p}{p}I'm planning to upgrade the headlight wiring on my Sentra because the stock wiring is WEAKsauce and and I'm using overwattage bulbs.  I know the basics from the Daniel Stern lighting site, my problem is in the selection of appropriate relays. {/p}{p}I know I want Bosch dual 87-pin (5 pin), but I'm not sure if I need a SPST or SPDT.  The reason for using the dual 87 is so I can send power to both headlights.  I'll use one relay for lowbeam and one for highbeam.  {/p}{p}I'm also confused in the tutorial where he's talking about common Japanese "ground switched" headlight systems.  "  {SPAN style="FONT-SIZE: 10pt; COLOR: black; FONT-FAMILY: inherit; mso-fareast-font-family: 'Arial'; mso-bidi-font-family: 'Arial'; mso-ansi-language: EN-US; mso-fareast-language: EN-US; mso-bidi-language: AR-SA"}{EM}It is tempting to run the existing headlamp feed wire to relay terminal 86 (trigger feed) and simply find a convenient ground for relay terminal 85 (trigger ground). However, this will not work with ground-switched systems. Run the vehicle's existing feed wire to terminal 86, and run the vehicle's existing ground wire to terminal85{/EM}.

Do you mean DPST or DPDT relay? Also if your headlights are grounded, then they are +ve switched.

I didn't use dual 87s. I used the standard bosch 5 pin relay. Power goes from the 87 to one headlight, then the other, using thick wires. If you're worried use two wires from 87.

You're right. the lamps dont need 2 relays. Besides I need to find out where I can get a dual pole relay. Do you know by any chance? I mean a relay that has two switches (dpst or dpdt) thanks.
