All on mod pic tutorial
Ok, so last year I converted my entire truck over to LED. I am using 80w led headlamps for both high and low beam. In order to get an increase in lighting the "All on mod" needs to be done. Here is what I did. Using a 12v min 1A diode available from just about any radio shack or electronics store I soldered a short lead of wire to each end and covered the exposed wire with heat shrink. Next you locate the high and low beam relays in the power distribution block under the hood. Once you have located these using the chart inside the cover, identify the hot post (#85) on each relay. Remove the 2 relays and install the diode between these 2 sockets in the block making sure the marking ring is towards the high beam relay. Insert the wires into the socket and reinstall the relays. This allows current to flow from the high beam circuit to the low beam circuit at the same time turning on all 4 headlights. If done correctly there is no risk of short or malfunction since you are using all the factory wiring and fuses.
