1993 240sx Cluster with Single Cam Wiring

[mgs_snake]

Hello, i just got a 1993 240sx and the HUD doesnt work i have read alot of fourms that they get messup over time so i wanted to change it to analog .. i brought a dohc cluster without the wiring thinking it would be plug and play snice i had dohc wiring i cant and i went to the junk yard but there was only a single cam and i took the wiring .. everything fit in my car harness but it didnt display anything .. no speed was read or the rpm .. so i wanted to know if there was a way i can cut the harness to make my cluster work. thanks
