How to find starter solenoid and replace on 2003 spyder

I could not find a solenoid listed so it must be built to the starter, the starter relay is right above the brake cylinder on the firewall (drivers side), looks like 2 black towers the relay is inside.

You'll find it where the transmission connects to the engine. Look at the engine, stand in front of car, it should be located to the rear of the engine to the left down low.

The starter solenoid is a part of the main starter itself..it is attached to the main starter,you can easily locate it by checking the POSITIVE post of the battery to which is the battery cable of the POSITIVE post of the goes through..it is located at the side part of the main starter, a tube shaped same as a glass shaped by its form..
