just wondering if its better to plug an apexi rsm into the ecu or the back of the cluster. im already running an aftermarket tacho off the cluster wiring, as i dont like the digital rpm read out of the RSM. apparently it is more accurate from behind the cluster?

makes very little difference where u tap it in,except cluster is usually closer to where u want to mount the RSM,saving time & materials.

speedo & ECU read the same wire = no difference.

ECU makes the input to the ICM,tacho reads the output of the ICM = very,very minute difference if ICM in good working order,as changes in the velocity & direction of current flow approach the speed of light.
