you checked both fuses right? the fuse to check is the one off the key switch which is the red/yellow to red wire.
You cant just unplug the key switch on the dual bulb headlight sleds and it will run, you need to jump the red/yellow to the brown to get it to run( bypass key switch). It was on the single bulb headlight sleds you could simply unplug the switch and they would run but without tach and lights.
