I have installed ML-ACR’s to replace Diode isolators as well as Big Boy systems. I remove everything that is no longer needed and then install the ML-ACR in the best place to make the electrical connections. You need two wires to the dash mounted switch, or you can install it without the remote switch and just let it do it’s thing. You can always override the operation using the yellow manual switch integrated to the ML-ACR.
