My name is ***** ***** I will assist you.

Can you take a picture of what you're looking at and attach it with the paperclip so I have an idea of what wire it is and where it is located? I can match it up to the one in the yard here and see what is not hooked up.

I'm an independent contractor and I don't get paid until a rating has been made.

We can go back and forth as needed to help resolve the issue you are having. Follow ups are free after ratings, so rate in confidence!

That... Battery to block, block to starter. That is the main fuse block to keep the starter from burning up. That isn't a 15 amp. Its's a 150 amp. You probably can't read the 0.

If the truck is starting, it was probably bypassed. They act up a lot.

well it doesn't start could you send me a picture of one that you have
Expert:  Jeremy replied 1 year ago.

I left already.

It is a battery cable to the side closest to you and the side farther goes right to the starter. There are no other lines. Just those 2.

Customer: replied 1 year ago.
that rear solenoid has nothing to do with starter?
Expert:  Jeremy replied 1 year ago.

That is a magnetic switch. It powers the ignition wire for the starter. That box is a large protection inline fuse for the starter's cranking to prevent the batteries from overheating when starting the truck.

They have two different jobs.

Customer: replied 1 year ago.
what is the job for the fuse than below it
Customer: replied 1 year ago.
when should the box have power
Expert:  Jeremy replied 1 year ago.

You're starting to go off the original question which is not allowed here. You asked how to hook it up and I told you.

I also explained what the box is and what it does.

Now we are going in circles and this is getting drug out. I mean since 930AM and no payment to me on top of that.

Good day.

Have a good day.
