Bykfixer Posted May 2, 2021 Share Posted May 2, 2021 What I saw on the net for both Toyota and Lexus was "check EFI fuse first". Here's a diagram. Hope it helps Quote Link to comment Share on other sites More sharing options...
geog1 Posted May 5, 2021 Author Share Posted May 5, 2021 Thanks for getting back to me. I checked every damn fuse I could find. What I wanted to verify, is the where (connector pin) of the B-Y 16 (E5). If the B-Y holds true for me, that may be useful. Haven't found 12v anywhere, yet.
