I just purchased a very clean and maintained 1994 Probe. I want to upgarde the headlights to H4. I did this same upgrade with my 77 280Z, to include 2 relays 1 for the low beams and 1 for the high beams. I noticed that in the haynes schamatics,that there is a relay that covers both head lights. Do you all spark chasers think it nessasary to still install 2 relays or should the one work? On the Probe fourm, a member did this same upgrade minus the double relay set up, so far no problem. The relay is to remove the load from the switch.
Cheers
