I replace the starter on my 94 F150 and must have put a wire on the wrong place. Does the negative wire go on the bolt that holds the starter to the frame, or does it goes on the post next to the positive wire?
If you have a picture or diagram I would appreciate your help.

The ground wire (neg) should attach to the starter mounting bolt (that bolts starter to the engine).

Thank you for the reply. I put the neg wire on the mounting bolt and the positive wire on the open terminal on the bendix spring unit attached to the starter. when I connet the battery I get lots of sparks.
I am not sure what you are calling neg wire.
None of the wires from the battery go to the starter unless it is a 4.9L engine then the NEG battery post wire goes to the starter mounting bolt. Other wise if 8 Cyl the NEG post wire goes to the engine block under the air pump.
The POS post wire from the battery goes to the starter solenoid post down on the starter.
There is also a Wire from the POS post of the battery that goes to the starter relay on the fender and a red wire from the other post of the starter relay that goes to a push on tab on the starter solenoid mount on top of the starter.
I do not know what you mean by bendix spring as Ford has not used a bendix spring since about 1955.
A Ford starter with a bendix spring:
The neg wire is a black wire I'm connecting to the mounting bolt. I put the red wire on the top terminal in the attached picture and the slide on smaller wire on the connector (shown as a bolt in the picture). I'm calling the bendix spring the thing with the positive connectors that is mounted onto the starter and is used to push the spring and gear out to move the flywheel. With this setup, I'm getting extra sparks/shorts when I connect the battery and the starter engages even though the key is off and is in park.
Thank you very much for taking the time to help.
I ould think what you are calling the bendix is actually the solenoid. I assume on the solenoid that you have two large terminals and the smaller push on one. Of the two large ones, one should have either a heavy gauge wire or a solid link going direct into the starter body. The other large terminal is the one that the heavy gauge pos. wire from the battery should be bolted to.
Thanks for the info. since I have the wires exactly as you said, and I'm getting shorts/sparks when connecting the battery, is it possible the solenoid inner component was rotated 180 degrees when I re-attached it to the starter? When I originally took the starter off, the solenoid was loose and the bolts fell out when the starter came out.
I took it that you were fitting a new starter. It may be that the solenoid is faulty, however disconnect the light gauge wire from it and then try reconnecting the battery. If no sparks and the starter does not run it may be that the fender mounted starter relay is bad.
I finally got the starter job complete, thanks to some great instructions from this forum. Turns out the initial check by Autozone was inaccurate as the local rebuild shop rebuilt the starter and everything is working great. I had the wires on correctly, but when the sparks started flying when I put the old starter back one, I figured I had the wires wrong.
Thanks again to everyone who sent me wiring diagrams and much need instructions! This novice really needed your help!
