87' Mercruiser 260/5.7 Alpha 1 gen 1.
Installed a New Engine that came with delco est, I have the original wire harness, I started the engine on the floor by jumping 5/6 drive current to 7 pin, started right away although I ran a separarate wire to the electric fuel pump ,
Now the engine is in place and trying to connect the electric pump which supposed to be connected with the oil sender , well the lite blue wire that goes to the oil sender only gives me 7v , not enough to run the fuel pump,
I ran the wires like I read in some posts and schematics from Don S. running a wire from the left side of the starter which supposed to be purple/ yellow ,but I don't have that wire in my harness so I ran one from there to the fuel pump then to the electric choke on the Holley 600 cfm, and then to the purple from ignition , so now my question is what do I do with the oil sender should I take another wire from the purple and connect it to it , seems like the only wire with current is the PURPLE from ignition, and also I have to take current from the Purple to the interruptor switch , wouldn't this Purple be overloaded?
