Im using a PMU 16 and MSEL Solid State Battery Isolator with a holley dominator ECU connected to a Holley Pro Dash. The dominator harness has a pre terminated CAN connection that connects to the pro dash and has a y connector to connect to other CAN devices. The wiring diagram for the holley harness shows 4 wires to the CAN connection 1. 12v switched input, CAN HI,CAN LO, EST GROUND OUT (not sure what that means). There is also a CAN HI 2 and CAN LO 2 on the J3 connector of the ECU. The wiring for the PMU and battery isolator only show CAN HI and CAN LO connections.
Question 1: Can i wire PMU and battery iso to the same CAN connections as the pro dash? If so do i just wire the CAN HI and CAN LO and ignore the power and ground connection?
Question 2: If the CAN bus connection to the prodash cant be used can i use the CAN 2 connections on J3? If so same question on what wires need connected.
