Hi all. A couple weeks ago we had a thread regarding Hella/IPF light upgrades which prompted me to order some parts. A classic Bronco forum had this wiring diagram online for doing a relay system and I thought I'd post it here for folks in search of one. Note: The relays I'm using are NAPA Part # AR274. I picked this relay because it has two #87 posts (i.e. the load going to each headlight). Not that you couldn't just split the silly wire but there you have it.
