Did an absolute terrible job explaining the fuse situation. For me, ground the black wire to the battery ground right by the fuse box. Take the #10 fuse he pulled and put in the adapter. Put the adapter into the slot where he pulled the #10 fuse from. Works perfect
This happened to me but I had to tow it to Toyota because it disabled the truck. The throttle body and wiring got fried. At least that's what the shop said.. covered under warranty though.
When i put the fuse in DRL fuse the lights would be on even if the truck was off i put the fuse in 10a INJ fuse and it turns on once i turn on my truck
