I am wondering how to switch from MPH and Mileage to KPH and Kilometers on my digital displays in my 1999 SSEi? I looked through my owners manual for almost one full hour and didn't see anything on how to switch.
I know the 1992-95? have a switch by the HUD controls, but my 1999 doesn't.
Anyone know how?
Thanks in advance,
Martin

The HUD switch only controls the HUD. We need a service manual for the 99. I bet you have to put in a few jumper wires.

I'm trying to switch the main digital guages also.
I'm picking up a 1992-1995 HUD control pod to see if that will hook up, but it probably won't and if it does no doubt the pin-out will be totally different.
Look at it as a learning experience -I know I will.

My totally-unscientific guess here is that it'* going to turn out to just be a jumper pin on a circuit board in the gauge cluster. After all, the pulse-counting and whatnot that'* used to calculate road speed doesn't need to be different; it'* only a matter of whether the answer on the dashboard is going to be displayed in MpH or KpH.

Hey, if that HUD don't work out.... The 93 could use one

Over my dead body!

ok gearheads.. I was wondering if I can get a PDF file sent to you guys of a HUD wiring from a 95.. you think you guys can figure it out?? ( Reason I"m being so generous is if it helps them great.. and if I can use it on my 97 SSEI.. BONUS ) and if you guys don't mind doing the hard part of going thru it.. THEN LIFE WOULD BE A BOWL OF CHERRIES for us all .. hee hee... talk about puttin our resident gearhead in a hard position.

might be weird saying this but I think the only way I know is if the HUD is in Km/H is if you were in Canada or something unless you had the 92-96? HUD with the switcjh for km/h to mph

Did you check http://134.39.200.6:9001/home.html for your wiring diagram? If you can't find a 97, then try the 98, then the 96, then the 99. Those are probably more applicable.
