ej into l to fit a lib auto there is 2 speed sensors one on the box one at the speedo.the ? is how or what do you do for the second one at the speedo when keeping the the l dash and speedo and not using the lib dash.

The one in the dash is only for the ECU speed sensor isn't it? Or is there another wire on auto models??

If it's just the ECU one off the dash your refering too... then u don't NEED to hook it up.

Although i have been told the L series dash does have a speed sensor wire behind the speedo some place.

The wire off the ECU that goes to the speedo i have found is more of a speed limiter than anything else. Doesn't appear to effect drivablity or fuel consumption.

The auto control unit uses both speed sensor 1 and 2 as inputs. Although it will still operate without spd2(the instrument cluster signal) it will set TCU codes and the shift will be compromised.

It is quite easy to enable the reed switch in the speedo head so I would recommend you do this as part of the wiring. Both the ecu and TCU will love you for it.

When you pull out L series cluster, look at the back where the speedo cable goes in.

Just to the left of it there are 2 holes where it looks like a screw can be inserted.
One will be labelled 100k (this is for the jap spec one which have a chime that goes off when you exceed 100km/h).
The other one is for the speedo signal output.
Insert a screw like the others on the back of the cluster & trace (with a multimeter) that circuit back to the pins (its not a straight run)

I'm not 100% sure though whether all the speedo mechanisms have the output built into them tho
