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.
