ROM data logger help

Hi, Its the weekend so I was unable to get a hold of RPM and would like to finish the car this weekend. I do not remember where the pinion pickup sensor plugs into on the data logger, is it the digital port? if so where does the little two pin pig tale coming off of it plug into? I have his papers but this part always confuses me.

I have a typical blown alky setup with Oil, fuel, and boost pressure as well as flow meter and pinion magnetic pickup.

Thanks for any and all help,

Just looked at the plug and it cannot go into the digital port but I have the tach signal off the power grid going into the rpm/dsrpm port so I am back to square one again

 

I just wired mine a couple weeks ago. The driveshaft / tach cable (ERPM/DRPM), plugs into the RPM labeled port in the unit. This is a dual cable, black for tach signal, grey for drive shaft hall sensor both going into one plug. The digital port, SRPM cable, I used for the clutch input shaft hall sensor. The plugs are different between the ERPM/ DRPM cable and the Dig/ SRPM cable. Hope this helps.

Something else I forgot to include. The 2 pin pigtail is for the tach input which goes into the black cable of the ERPM/DRPM dual cable.

 

Thanks for the help, I realized my mistake shortly after posting this. The other cable I have that was marked drive shaft rpm and had a 3 pin plug instead of the two, it was leftover from a previous build but was in the same bag and threw me off. I need to order two cable and cut one to length and she is finished. Thanks again, Trev
