then you need to catch a tach signal at the distributor on the ignitor wire, on my car b16a obd-0 its on the 2 pin plug, the one on the right side, not sure where it is on that distro. you need to get a manual and look for the ignitor wire off the distributor and tap it there, but i gaurantee theres a place at the ecu to catch the tach signal, your just not looking in the right spot

You can also get the signal from the dead end plug on the drivers side wiring harness. Blue wire, with a female connector.
