starter solenoid

i have a 2007 inetrnational 9400i , having starter problems. does anyone know if this truck has a firewall mounted solenoid like the freightliners do ?
i know theres 1 on the starter itself , but there should be another one on the firewall or chassis . i cant find it .

 

Yah, they are bolted to the firewall at the right side. Upper, outside corner by the air cleaner housing, under the cowl tray.

Looks like this;

 

thanks , i will look at it.
