I check all the connection and all the grounds but its still draining 12v from the battery when i turn everything off. What can be draining that which?

 

same thing happens when i leave my eclipse w/alarm on for more than 3 days w/o starting it and i have a optima bluetop

 

im going through the samething right now, basically the way i understand it dependning what sr you have the constant power drains the battery for some reason still dunno how or why but if you figure it out i wanna know to.......

 

I found the problem, it was in the main wiring harness. I grounded the o2 wire to two other hot wires instead of using a wire from the plugs.

 

awesome
