Naked Buell Posted February 2, 2012 Share Posted February 2, 2012 I am doing a 2.2T swap into my 85 Brat. I am also putting in a 5 speed jdm transmission. Do I just hook up the vss from the tranny to the ecu????? Pin B58, pin 11 says vss. Does it just connect to the transmission????? Link to comment Share on other sites More sharing options...
ShawnW Posted February 2, 2012 Share Posted February 2, 2012 No. On a Brat the VSS is driven off the back of the speedo head. Its got its own wire and spade terminal. I think the wire is yellow. Connect that wire to the 2.2 Ecm pin you mentioned. Link to comment Share on other sites More sharing options...

Numbchux Posted February 2, 2012 Share Posted February 2, 2012 If your transmission is newer, it will have an electronic sensor in it, that can be used for the VSS on the ECU. But, if you want the stock brat speedo to work, you will need to use a cable (a cable will thread right in place of the sensor if you have a newer trans). And use the reed switch in the gauge for the VSS. Link to comment Share on other sites More sharing options...
