Well I don't have a schematic for a 94-97, but I acan explain how to do it.
All you have to do, is have the high beam circuit trigger a relay that keeps the low beams on when the high beams come on. To make it all work right, you will need to remove the high beam wire from the stock headlight socket. That wire will now be used for the new high beams. If you don'tremove it, BOTH filaments in the low beam housing will be on when the high beams are on. That will create too much heat. This will now be used for the new high beams.
Now, to make the custom "brite-box" work. Have the high beam circuit activate a relay that brings power back to the low beams. As you know, the low beams go off when the high beams come on. So basically all you are doing, is re-directing power tot he low beams when the high beams come on. Am I making sense?
This is a fairly easy way to do it, and no need to shell out a bunch of money for the Geno's "Brite-Box," which is a HUGE ripoff if you ask me... You can accomplish the same thing with $10 worth of wire and and a relay.
