i was told by the shop that i bought my engine from that in order for me to get the vtec to work i needed to buy a msd rpm switch from summit racing. but from what i have read on here all i need to do is run wires from the ecu. am i wrong here or what? my car is a 93 civic that had a 1.5 non vtec, and i have a 1.5 vtec motor to go into it.
