How to install US ELLIPSOIDS using my plug and play connector set!

[MR 325]

As you might know I sell plug and play connector sets to convert your factory sealed beam E30 to US ellipsoids with no cutting or splicing of any wiring! A cheap and simple solution to your headlight upgrade. After doing an install for a friend using these connectors, I decided to make a quick DIY post about it.

I NO LONGER SELL THESE!!!!!!




Before:



Step 1, remove grilles. Three clips on top edge of grille and one phillips screw in each bottom corner of grille:



Step 2, remove headlight assembly. The large phillips screws. Carefully unplug headlights:




Step 3, install plug and play connector in to high beam socket. Brown wire always goes to brown wire, this is ground:



Step 4, install plug and play connector in to low beam socket. Brown wire always goes to brown wire. The factory low beam connector has slots for three wires, with your ellipsoids only two will be used. The NON-brown color wire goes in the socket closest to the brown wire, as shown:




Step 5, plug your wiring connectors in to your US ellipsoid light bulbs:



Step 6, install your US ellipsoid assembly in to place. It's a good idea to double check that your lights and light bulbs work before tightening it down in there:



Step 7, reinstall your headlight grille using three clips on op and one screw on each side at the bottom:



That's it, you're done! Hope that writeup will help you guys out, and thanks for buying my connectors!

Great diy, I was wondering, Is it possible to just change the outer lights to the elipsoid and leave the innder highs as the stock ones?

Hey Matt,

Idk if it makes a differance, but my eta is an '86 and both of the connectors needed to go in the brown ground (seated all the way to the left on both terminals) and the top (one yellow wire on he low beam and two white wires on the high beam) so all four of mine looked like your high beam set up.

awkward. lol

anyway, you should sticky this for other people who are not as electronically inclined.

very nice writeup
I didn't realize how straight forward the swap was, and how easy it is to wire it.

Low beam 900x style plug is PnP to 99.9% of aftermarket HID kits. Then just install 9006 HID bulb in housing.

Done.




OP,

Check your sale thread. Interested in buying a set.

Yes you need run a jumper between pin #30 on both the low beam and high beam relay.
I own a 91 318is an the bentley was wrong about the placement of the relays in the fuse box. I pulled relays until I found both of them.

Maybe because your car isn't covered by the manual. . . They might have changed it on the 318.
