testing Ignition module - 1/26/2008 10:48:49 AM    fjdavid   Posts: 9 Joined: 1/15/2008 Status: offline     I have a 99 suburban with 5.7 L 4wd. I'm trying to test the ignition module using the Actron sensor tester Pro. The manual shows the 4 pin GM module as the module in the distributor with 2 connectors on each side. I have the external control module that is a 4 pin with a single connector with 4 pins in a row. see image below. I don't know how to connect this tester to the module to check. I haven't been able to find a pin out diagram for this module. If you can help I'd appreciate it. thanks, Frank Thumbnail Image Attachment (2) < Message edited by fjdavid -- 1/26/2008 10:53:33 AM > Post #: 1
