    Yet again picking up a sleeping thread...I've heeded various advice about headlight voltage and have brought clean power on #10 wire to both sides. (This coach has the 120mm H1 Hellas.)  I'm planning to put jumpers at the old relays to send the switch closures to the new relay locations at the headlights.   

In tracing the old relay inputs, it's pretty clear that the low (outside) beams are a simple ST closure from the Lights switch.    But the hi/low switch on the turn signal stalk doesn't seem to do anything to the hi/low relay.    The latter also has 12V on a different pin than on the Headlights relay.    What am I missing?   
Thanks!
