Does anyone know how to make the Lows stay on when you flip the highs on with a 2000 Chevy silverado and a 05 Colorado? I dont want to buy the relay kit for 60 bucks so on my 07 Silverado classic I did the diode trick from the hdlmp hi to hdlmp low relays and it worked good and all but on the two trucks listed above they dont have both those relays, they only have a hdlmp one. does anyone know any tricks to do what i did to my 07?
please and thank you
