LT 4 question
 

i have one problem right now on my harness of my LT-4, it say on the diagram that teres should be a white cable that is for the tach signal, but the harness have marked that is for auxiliary output, im confuse right now about it so can somebody can help me a little? ill apreciate it thanks

the white wire on the LT4 is for the ign input from the neg side of the leading coil,

have a look in the manual for the pinouts of the ecu and make sure it is in the correct spot
