k im trying to wire up my zeitronix datalogger/wideband and cant seem to figure out where the ecu gets its rmp signal from. ive been looking at the diagram from phearable.net and cant seem to find anything distributor related. would it b ignition control module (A 21 and 22)? im lost and really need this to tune. any help/suggestions are welcome. i already got tps hooked up and all the power/ground wires, i just need the rpm wire now. thanks in advance!!
