EF SiR Cluster Problems
 

I've installing a SiR (90-91) cluster into my EF Sedan (91 EX model), and im having a few problems.


Speedo doesnt work, however sometimes I get a code 17 and sometimes I dont. I've triple checked the wiring however, and its ll correct for the VSS.
Im getting the correct 2-4v on my electronic VSS.
Vtec does not engage. ( I have a JDM B16a first gen PR3 ECU)

Any help or suggestions would be appreciated.
