I know this thread may be a bit long in the tooth, but if you find a junked Eagle the headlight mod is really easy to make using a few parts and some spare wiring.
On the passenger side fender under the hood near the firewall are 2 relays, unbolt those, cut the wires and BAM, you have your high/low relay holders ready to go. Pick up 2x40 AMP relays.
Remove the stock Eagle headlight harnesses and use the 4 plastic connectors. I used 12 gauge wiring to put it all together.
I used this to build my headlight relay system (as well as for offroad lights). Keep in mind that my headlights are converted from a Jeep so the low beam lines just carry to the low beam bulbs.
Something interesting I found out though, the Jeep lights are just a larger version of the Eagle Hi/Low beams, which means that technically you can get 4 of those and rewire the connectors to have 4 headlights ripping the universe a new
when you do this mod.
