I did the relay thing in my GM, it needed it. Picked up another lighting harness, pinned it to a sheet of Styrofoam, replaced the 16 ga. with 12. ga and ran it all through a fuse box from a Shadow (?). Put a large plug on the front of the box (Lincoln power seat plug) and mounted on the inner fender. Rewired the fuse box the way I wanted. Picked up over 1.6 V to the lights (Hellas). Marvy.
