Using the #4 wire, connected positive side of battery to master relay. Other side of master relay connected to starter. Connected negative/ground side of battery to master relay case where it is bolted to firewall. Lower bolt on relay case connected to #4 wire which is connected to engiine. The photo guide actually shows the wrong place to connect engine ground wire. It will work but it is not the preferred location. The actual location is just to the right of what is shown in the photo guide. Still trying to decide bes way to wire power up to ECU, Fuel pumps and any otther critical components to make sure engine can still run if battery or alternator malfunction.
