"The Data Link Connector (DLC) is the multi-pin diagnostic connection port for automobiles and trucks used to interface a scan tool with the control modules of a given vehicle and access On-Board Diagnostics and live data streams." (wikipedia)

This is a very simple schematic wiring diagrams. In this schematic wiring diagrams, you will able to see some parts that build this circuit, such as:

• Power train control module. Power-train control module (PCM), also known as engine control unit (ECU) or engine control module (ECM) is a type of electronic control unit that determines the amount of fuel, ignition timing and other parameters an internal combustion engine needs to keep running.

• Fuel pump relay. It is usually used by the engine control module (ecm) in controlling the timing when the fuel pump is turned on. It also supplies the electric current to the fuel pump to power up and down. (ehow)

• Brake pressure modulator valve. It is a combined assembly of the electronic control unit and hydraulic control unit, used in some vehicles. It is also called the Electro-Hydraulic Control Unit (EHCU). (motoera)

• Remote keyless entry module.

• Radio

• Diagnostic energy reserve module. It maintains a reserve voltage supply to provide deployment energy for a few seconds when the vehicle voltage is low or lost in a frontal crash.

You are also about to see the wire color coding which purposed to ease you in determining the wire. 

So after reading the brief descriptions above I hope you will get an enough understanding in doing your wiring works. For detail image of 1995 System Wiring Diagrams Chevrolet  Tahoe Computer Data Lines/Data Link Connector Circuit, you can see the image below.
