ive had a few problems since i installed the trip computer into my 94 xr6,
got a problem with my odonameter, when i turn my head lights on it
switches itself right off, it hould dim but its just black and i cant read it at
night but as soon as i turn the head light off its bright and normal???

its got me stuffed fellas

is there any posts like this? got any suggestions??

I'd guess that you've tapped into a wrong wire somewhere when you've added your trip computer.

What model (ED or EF?) and cluster type have you got?
Do all of the other instrument lights come on and dim properly?
Have you checked a schematic?

Try searching the forums for "trip computer" and "odometer".
