just picked up a complete turn key 73 1600 carb engine in order to get the 75 back on the road, the original engine ran good but the crank bearing is turning in the case and spewing oil every where . so i had already put an after market exhaust and normal heater boxes on the fi motor ,work great by the way so they should be ok, i figured on blocking one fuel line at the tank bypassing the high pressure pump using the fi filter where it is now what to do with the wiring?? unplug the box , then what ? what wiring do i need and what can i eliminate, anyone ever do this??/
