I have 97 with a 99 Engine and 99 sensors.
(97 AC, PS and Alternator)
(99 Crank Sensor and 99 CAM Sensor)
LS2 Truck coils, ID 1000 injectors.
I bought Megasquirt MS3X ecu with diyautotune pigtail from a member here. It is configured for full sequential. He build a PnP harness to connect the MS3X to my 97 Harness.
When reviewing the pigtails, I am not sure if it is wired correctly. Looks like the wires are crossed or I am not looking at it correctly.
Also all the four AC related connectors (AC In, AC Out, Main Fan, AC Fan) are connected to a single wire from MS3X (MS3X - 1). Is this correct?
I have attached the diagram that explains better.
