So I tested the power harness to the ECM this morning. The blue wire has 12v but the blue/red wire only has 8v and 9v with the ignition on. Any ideas what would cause the lower voltage?
I'm currently experiencing the same issue. Just installed a new multiplex ecu and nothing. I bet my issue is the same wire. Do you have a picture of what part of the harness lost continuity?
Finally got rid of the Daystar spacers and Installed Total Chaos UCA, Icon Ext 2.5 Remote Resi up front and 2.5 Standard Remote Resi in the rear. Kept the 1.5 Daystar in the driverside rear to help correct lean.
