I can now turn over the ignition but a couple of wires have been disconnected and I need to know what proper wiring to ignition looks like

Bulbs and fuses are good

1995 cutlass ciera oldsmobile .
I bought this car a few weeks ago everything was running great the car sat for about a year. The first thing I did was top off tranny fluid, oils changed ect. It was driving great.
I start my car no problems and when I drive it to about 15 mph it doesn't shift and acts like it's going into over drive which makes the check engine light turn on after it doesn't shift and i let off the gas and the car drives fine again with no shifting problems until the next time I have to turn it off and start it again. Could bad transmission fluid cause this?

I have change relay checked fuses and it will run if i jump the pump the grey wire on the relay. I found tge wire harness plug in the trunk was rotten. I cut and spliced them and made a new ground and still it wont send power to the pump with the key.
Any ideas?

There is a gray and red wire

The cruise control and anti lock brakes went out at the same time. Changed the fuse that both were on. it didn't solve the problem.
