A few weeks a go my truck got broken into and they completely destroyed my dash. Insurance paid for a new dash and I had the Ford Dealership install it.
Needless to say, in rewiring my factory stereo, transfer case switch, cig lighter, and air bag indicator (into the radio bezel), they obviously didnt re-wire my OHC.
Tonight I rewired it, and my problem is that when the headlights are on, the display flickers It does in fact dim properly, but has an annoying flicker that is intermittent (sometimes it flickers, I turn the headlights off and then back on, and the flickering stops). It does not flicker at all with the headlights off leading my to beleive that there is a problem with the dimming function, but I do not know where to begin looking for this bug. Do you guys think that it is an issue with my wiring or the OHC itself?
Here is the wiring instructions from Bob aka "rwenzing":
Ranger Power Sports Forum - View Single Post - 07-08 Wiring question:
Explorer Overhead Console ---> 07~08 Ranger
Console Power: Yellow/Gray ---> White/Blue (white wire with blue stripe - radio harness)
Console Ground: Black ---> chassis ground
Console Night Dim: Light Blue/Red or Red/Black ---> Blue/White (blue wire with white stripe - radio harness)
Console Maps: Green/Orange ---> Violet/Red (radio harness)
Console Dome: Black/Blue ---> Green/Blue (above factory dome)
Console VSS: Gray/Black ---> Purple/Orange (pin #1 of the center PCM connector)
These two would be wired separately from the truck harness:
Console temp: Dark Blue/White ---> Temp sensor Dark Blue/White
Console temp: Dark Blue/Yellow ---> Temp sensor Dark Blue/Yellow
(Important: the 2007~2008 Ranger no longer has practical way to tap the "Battery Saver" feature for use with the Ex console map lights. So, if a map light is wired to a constant hot (Violet/Red as shown above) and it is inadvertently left on overnight, it could kill the battery. An alternative would be to wire the maps to the keyed console power (White/Blue referenced above). Of course, then the maps would only work with the key in the RUN or ACC position. It's a matter of preference.)
