Did you install and plug everything right? Are you using a manual to install it or are you just winging it?

Well.. it was a thread i found on google witch explained where to put what. BUT it was a Mitsubishi... couldnt find anything like it in 200sx forums anywhere so i started there.
I found illumination (white) ground (black) Ignition (brown) and Constant power (red).

I wired it into the cigarette illumination ignition and ground, with a constant from the battery directley because i couldnt find ANY constant at all behind the dash!

It seems it needs some time maybe, or it is in front buttons to push but i have NO idea why or what happens if i do it!

If all the sensors are installed correctly, and you have constant, ground, and illumination on the link unit; It should be working. Being that you connected all the harness into the right slots on the control unit.

PS there are a TON of constants behind the dash. Wire it up right.

just double check again,, make sure you have 12v constant,, and 12v when Ignition is On position ,, check your ground, if all of above input are there, check see if your plug it in right slot, (most likely not), then you may have death control unit.

RED= 12 V constant ( positive)
ORANGE= IGN
WHITE = Illumination
BLACK= Ground (negative)

BAR to PSI to KPa Converter (http://www.tvr-webmart.co.uk/tvr_info_psi.asp)
