2001 nissan quest rms, crank but no start

yes the purpose is the same, however the relay adds isolation for each circuit. starter 1 controls the starter solenoid relay starter 2 controls engine management, etc. hypothetical situation here. Lets say one day your start solenoid gets stuck and somehow back feeds 12v constant down starter 1. Your HACK "jumper" solution will cause the second start 2 to get a constant 12v signal, even though that wire is only suppose to receive 12v for ~2-10s during hard crank. Just my 2cents. remember its your vehicle, not ours. Many knowledgeable electrical installers on this forum would agree, for the cost of a relay just use one. Ted

X 2 with Ted, simple test, use your meter to see if these two wires are continuous during off, ACC, Ign and start. If they are don't bother with the relay. I already know the answer. Effectively what you're saying is that you don't agree with the perceived opinion of the manufacturers, DEI, Compustar, etc. etc. or installers. Things are done for a reason.
