very good so now I have my wires labeled. what about the points on the ecu itself. using the first link t5-b there are points for rpm signal 1 and 2. but i have only one rmp wire. and the karman diagram on one you provided don't specify 2 rpm signal wires. or a splice / cut. like the air in/out any thoughts?
it says regular connection rmp 1
plural connection rmp2. what the heck does that mean?
