How to install Battery brain help please

[tlong831]

Ok I got my battery brain in the mail today and I was hoping it would be easy to install ... for those of you that dont know what it is.. it's a product that saves your battery from draining below 11.7 volts or something so your car will be able to start. ANYWAYS

the hardest part of installation looks like the part where you have to find the "engine on wire" this wire has to go to the battery brain and has to get 12v when the car is in ACC or ON and O volts when the car is off. I'm thinking the fuse panel.. I dont want to buy a electric tester... so can someone just tell me what I am lookin for .. I hope so Thanks!

Find a Toyota repair manual and look for that wire in the chapters that have to do with the electric system.

yea I did that I have the toyota service manual for the 93 corolla and it's pretty confusing to figure out what I am asking... I am thinking now that the wire is the remote on /power anntenna wire that goes to my amplifier.. I will probally try that wire because I dont know what fuse to use in the engine bay.
