"1989 Tempo/Topaz Electrical & Vacuum Troubleshooting Manual" Written for Ford dealership mechanics, this book will help you troubleshoot or diagnose electrical and vacuum problems. You will find electrical and vacuum diagrams broken down so that you can perform specific tests. Look for troubleshooting maps and/or diagnostic trees designed to take you through the process of finding your problem(s) step by step. The specifications in this book will help you to understand connector configurations, and locate & identify harnesses, circuits, relays, and grounds. The vacuum diagrams indicate flow, valve & sensor locations, hose colors, and vacuum distribution. In many cases, this type of book can be used in place of a wiring and/or vacuum diagram. However, you will need a separate book for emissions related vacuum repair instructions and diagrams. This manual covers all of the 1989 Ford Tempo models including the GL, GLS, LX and AWD. It also covers all of the 1989 Mercury Topaz models including the GS, LS, XR5, and LTS. This book measures 11" x 8.5" and is 0.27" thick. Buy now to own the best manual for your vehicle.
mostly electrical
There is only on very limited vacuum diagram in this book showing power brake booster, to speed control, vacuum reservoir and all-wheel drive vacuum solenoids. Very disappointing. No emission component ID at all that I could find unless I'm missing something.
