where is the speed sensor wire?

 

go to Johns cardomain i think he has it on there Alon...

 

i've been using that and its not on there....... at least i cant find it

 

you need to know the wire color on OHC or where it is located on the truck?

 

where its located onthe truck

 

VSS? It's the grey wire in the GEM module behind the radio. I believe Grey with a Red/Maroon stripe.

 

Gray/black at the GEM to the left of the radio.

 

And that is from the bottom of my cardomain page on the wiring. Are you ADD like me, Alon, lol? You have to read the ENTIRE page!

 

I told gim Grey/Maroon...oops. I was close for not even SEEING a Ranger for over a year!

 

I had to tap mine by the parking brake as it came from the firewall . . . mine an '04 though

 

Sadly, I have not technical data on '03 and up Rangers -- a situation I need to rectify! I have service manuals for everything from 1992 to 2002 though.

 

jeese, my friend and i both read your cardomain a few times and totally missed it........


thanks john!

 

now that everything is wired up, when i dim the interior lights the console gets brighter and when the interior lights are supposed to be fully bright, the ohc gets dim...... john...help me!!!!!!!!!!!

 

Recheck your wiring is all I can say. Question: what does the console do when the lights are off?

 

Mine does the same thing, Alon. The Explorer uses a completely different style of dimming module from the one in the Ranger. It is more a more sophisticated unit and I plan to get one for my Ranger to hopefully correct this.

 

Bob, what is the difference that would cause it to work like that? This is the first I've heard of this problem. What year explorer consoles are affected, if you have that info?

 

Don't know what year mine is but it's green, so 98~2001. The Explorer dimming unit is pulse width modulated but the Ranger looks like a variable resistor. I'm not sure how the electronics interact between the two, just that my 99 Explorer book shows the different diming module from anything in the Ranger books.

 

Well, on some explorers there are two illumination lines. One of them is red/black and I know on one console I had that setup and only the red/black wire worked for the illumination -- I think. I don't remember. It could be that one line supplies power, and the other line is "ground", but PWM modulated. If so, grounding the PWM line, and supplying power from the resistive dimmer to the other line would solve the problem. Did you end up with any "extra" wires on your setup?

Although, since the unit is electronic, it may not see the other line, and respond only to the dimmer line, don't know. I'm going to have to research it a bit, I guess.

I've installed some 98-2001 consoles and this problem hasn't cropped up. I'm real curious as to what there is about your units that are different and exactly what dates they are from. A PWM dimmer and resistive one should work the same -- but obviously SOMETHINGS up with this system.

 

Well, I just bought a 1998 ohc, so I guess I'll be the guinne pig.
