93 Galant 4G63 Bee *R Rev Limiter Install

Hey guys im trying to install a rev limiter on my 93 Galant HJ. Would anyone have the ECU pinouts specific for this car because ive tried heaps of ecu diagrams like the Evo III and Mirage because apparently they have the same pinouts. Im assuming i need the Crank Angle sensor and the RPM signal from the ecu.

Ive tried to connect them from the distributorn just to test it cs i know theres a crank angle sensor there and also a rpm signal and i got it to work but it doesnt functionn properly. Whatever rpm i set it to limit it it doesnt work at all. It cuts in the whole rpm range but it doesnt hold it. Like if i press on the gas halfway it will limit the revs at a certain rpm but if i press my foot more then it will go up the revs so obviously it doesnt hold it like it should. Do you guys think i got the wrong rpm signal wire?

Appreciate any help guys Cheers
