I bought an '88 trans am with an automatic with no wire harness. I put my 87 305 tpi 5 speed and wire harness into the body of the '88 trans.

When wiring, everything seemed to plug in correctly. EXCEPT when I got through the last connections to the computer. I have one extra plug. I cannot find any place to plug it in. Please refer to the picture attached

Also, the fuel pump will not run - there is no power to the fuel pump.

I am thinking that these two problems are related. Does anyone have any idea what I need to do from here?

Thanks,
Chuck
