O.K. I GOT MY MSD DIGITAL W/S FOR MY WET ZEX NITROUS, I GOT EVERY CONECTED BUT THE MSD DOESNT READ THE RPMS. I KNOWS ITS THE #35 PIN FOR 98'S, BUT WHEN I CONNECT THE WHITE WIRE TO THE #35 MY TACH IN THE CAR DOESNT WORK OR THE MSD(BY NOT READING THE RPMS)

THIS IS HOW ITS CONNECTED

YELLOW- BLACK WIRE FROM ZEX BOX
BLACK-NEG ON THE CAR(NOT THE SAME NEG THATS WITH THE ZEX)
WHITE-TO #35
RED-TO THE ON SWITCH FOR THE NITROUS
GRAY-NOT USE
ITS ON 4 CYC MODE
NO RELAY- I TRY THE RELAY BUT GOT MAD AND JUST TOOK IT OFF
