Replaced starter solenoid and now I have all the wires messed up.
I really need to know what other wires go connected to battery terminals. Negative goes to post on starter at the bottom of the car then a smaller wire coming from negative to ground. what other wire goes to positive terminal other than connected to starter solenoid?

Here is a diagram of the starter wiring and part of the main wiring diagram that shows the battery connections in the top right hand corner of the page. That should help.

That ground from ECA is the ground from the electronic control assembly at pin 60, a black/light green wire.

I am hoping it is this one you are talking about. Another question, after replacing fuel pump how much gas should my tank have before starting?

I would say at least three gallons, but I do not think that specification is listed in any repair manual.
Why are you showing me those photos?
I see the inline fuse, are you asking where it goes?

I wanted to be sure that the wire was correct. first picture was an accident but the second wire, the black and green is the one I could not figure out. Thanks.

What on the vehicle does not work right now?
exactly where is the one end of that coming from?
Is the fuse in that fuse holder not blown?
I think that looks like someone added that inline fuse holder on. Is there like a radio amplifier or something added on?
