Good evening,

I attached the engine diagram for you and larger images as well

Download it to your computer and enlarge it and then print it out. It gives wire colors and the name of the components.

Cant see the diagram. It's blurry? Can you send me how to hook the starter up on the car listed above? I need a picture not a diagram of where the wires go on the starter.

I got the starter on and wires reassembled on the 1994 Deville. I am finishing up hooking up last of engine parts. Problem has been I didn't take the engine out I was brought in the second half of it by reinstalling the engine. The person who took it out is not here to ask. I have a red positive wire coming from the battery that goes through and hooks somewhere but I can't find. Any pointers?

The positive cable red wire from the battery goes on the solenoid on the big terminal.

In your picture, it shows the cable right at the nut on the right side.

Wire comes out of the cluster from the positive battery connection and goes through the front of the engine compartment to the drivers side and is very long. It has a big eye hook at the end for a bolt to go in and then the nut with the eye-hook goes to? Not the starter. I already have the starter in and complete.
