Sorry guys you probably get tired of hearing about OHC's. I put mine in today and everything seems to work the way it should except for the temperature reading, it is reading -40 degrees in F and C. I did hook up to the VSS. What do you guys think?

 

and you hooked up the temp sensor? if so, you may have a bad sensor

 

Bad sensor
Bad connection on the temp sensor connections

Check connections first

 

Mine said the same until I got the temp sensor hooked up. You can get a new one at any auto parts store I believe.

 

i have also noticed that my dimmer switch is backwards when my gauge cluster dims the ohc gets brighter

 

The dimmer is suppose to work? wow lol mine dosen't oh well might check it when I put a new deck in, Yea it is probably your temp sensor.

 

Some Rangers have trouble with this and some don't. It might have something to do with the year of the console. I had to install a 99 Explorer dimming module to make my 99 console stop doing that. It is not plug and play though.

 

My console is from a 98 Im not to worried about it because the ohc only gets brighter when the dash lights are totally dimmed down.
