Fixing ground and shorts? Ground locations and wire color codes?

Hi ken thanks again for the help for 2005 Cadillac CTS 3.6l Vin 7. On the ground locations can I get pictures with the names of the ground locations? The ones you sent are small and hard to read. Also, the color codes. The wires running under seats is there a several grounds? And how many will affect the speedometer, cruise, ect, ect? Those are the locations I'm hoping will fix this or do you all the grounds affect it? I appreciate your help. This car is a big pain with all these sensors. Thanks again

Hi Ken, thanks for answer to last question. The diagrams of ground locations are fine, but can I get pictures with the names of ground locations from under hood, under dash, and under seats, etc, and any other locations that I should check? Also, wire color codes need. All the sensors on this car make it a giant pain. I couldn't afford to have a shop check all of this so thank you very much for your help and if you have any suggestions or more information that I need to check I would really appreciate it. Thank you again, have a good day.

Yes, are there pictures of the ground locations? Took it auto zone and had scanner hooked up. Trouble codes power train system-secondar DTCs-po573-00-brake switch circuit 1high voltage. Anti-lock brake system b3903, c0460-steering position sensor malfunction, c0461-steering position sensor range, u100-class 2 data link malfunction. The check engine light is off. Engine runs okay. Transmission shifts okay. Odometer reads 150000 + plus miles. Scanner reads 1385 miles. I can't afford to take to shop and pay for them to search for hours to find problem unless that' my last resort. I would appreciate your help, thanks.
