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!!

-faded-

neal would be the man to talk to

I believe it's the blue wire on the distibutor plug

sleepinsol

where does that come out on the ecu?

and yea i hope neal sees this lol.

According to this guy Honda-Tech.com: Honda Civic/Del Sol (1992 - 2000): RPM signal for OBD1 P30? it's pin A21

sleepinsol

thanks....im not running a p30 ecu, but i dont think that has any effect on the signal correct?

sleepinsol

also for vega's diagram it says that A21 is red/green, and on the other it says that A21 is yellow green. gosh im confused again! lol

EGKID

I would just wait for neal or vega to chime in, most people(from my search) seem to get the rpm signal from the blue wire from behind the gauge cluster but that seems like a pita taking out the cluster and what not.

i gotta wire it to the ecu bc thats where the datalogger has to be set up. lol i dont have wires long enough to get behind the dash. i managed to find the tps wire easily, but the rpm signal is whats throwin me off. thanks for helpin tho! repd!
