Volt/Ohm Meter:A Volt/Ohm meter is always a good tool tohave on hand when installing any type ofelectrical components into any vehicle. Mostbasic units provide the two functions requiredto diagnose electrical issues seen during aharness install. These two functions are theability to read DC Voltage and electricalcontinuity or Ohms. They can be purchasedfrom any home improvement store, localhardware store and electrical supply shopand online.Electric Drill, Bits and Hole Saws:Needed if you plan to mount the ECM, TCM and fuse block inside the vehicle’spassenger compartment and also useful to drill mounting holes for these components tobe bolted down.Heat Gun:Very useful to shrink the heat-shrink used on the alternator charge wire and the heatshrinkableterminals for the electric fan and crank signal wires.7
Disconnect battery cables from thebattery and then unplug the ECM, TCMand Alternator before any welding isdone on the vehicle. If you don’t, youwill cause permanent damage to thesecomponents.8
