    Default 86 dash harness, no power to fuel pump relay

    Hey guys new to the forum im hoping someone can help me out. I have a 85 gt that has a 86 fuel injected 5.0 from an 86 so i have the wiring harnesses from an 86. Now when i turn the key i have no power to the fuel pump. Yesterday i found out that there is a small 3 pin connector that the yellow wire from the fuel pump relay goes to and it has nothing to plug into there for it would never have power at the fuel pump relay. The connector also has a tan with green dots and the red wich i assume goes to the inertia switch.

    Side note the fuel pump relay is new, the eec relay is new, i tried a different A9P computer also checked the inertia switch. And i checked fused links up by the starter solenoid.

    For some reason it wont let me upload a jpg image so if someone wants to see what the plug looks like i can send you a pic.

    There is a fuel pump inertia switch in the back of the car under the trunk rear trim cover. The pump won't run without this switch. It's a reset able switch.
