I did the #4 wire straight to the + battery post.So far so good.Before running the stereo or not starting it right on the first turn of the key causes my 2wd 22re 91 Toyota not to start.Many times had to kick start it.
The starting relay is located on the driver panel and it says "starter relay".Finding the wire is tricky but I matched up the male diagram and went ahead by cutting and soldering the #4 wire to the battery.
I changed the key ignition,battery,checked starter contacts looked fine.
Thanks for the tech modification.
