Harness Test Leads

If you are needing to troubleshoot an ECM or sensor these terminated leads will enable you to do it the right way.  You can also use these leads to check terminal tension.  Using a multimeter probe to test a terminal can spread the contacts and damage the terminal.  There are two of each terminal type found in GM standalone harnesses.

Blue – 150 Series Terminals

White – 280 Series Terminals

Red – 100 Series Terminals
