This one has plagued me for more than 10 years and i have never been able to have high and low beams work. It's either one or the other depending on how i hooked up the relays. I will beat it now if it kills me, so can someone please help!!
The 3 wires of interest that are used to connect to the relays for headlight upgrade are R, RW (low beam earth) and RB (high beam earth). Simple, right?
The mystery is why I am getting power (with test light) through the R but also RW wire with low beam?? This should not be happening and stops me from correctly hooking everything up.
This is more serious than an inspection lamp
