    finally finishing my plow lights

    the plow I have is off a 95 dodge ram with the single bulb head lamps and i installed it on my 01 dodge ram with the quad bulb setup

    so the original harness i had wouldnt work since it only had two socket adapters instead of the four i needed

    for the past two years i wired the plow low and high beams up to a switch in the cab

    finally this year during my down time i built the relay setup for the headlamps


    while looking and following along with westerns relay diagram and instructions i noticed it requires a diode to be placed between the plow high beam relay to the truck outer high beam relay

    what kinda of diode is this? i have some 3amp diodes laying around for some reason so i was going to try them but I wanted to check and see if it may have to be a specific one

    thanks!

    3 amps are good for just about anything. They'll be fine.

    B&B - got it working! no more messing with stupid switches, everything works as if it came from a dealer - and i was able to save the 100 or so for the harness by making my own.

    the diode gave me a problem at first. everything was working but not high beams on the plow. i swapped ends on the diode and it works


    thanks

    Yes you do have to get them in the correct direction for them to do their job. Congrats on the DIY savings. Thumbs Up
