The orange goes to a fuse that is always on. That's how it remembers things when it is powered down.Like the clock on a Car stereo.

Twist red and orange together and hook to power then put the black to ground

Midland 77-118. Three wires coming out of unit red,black,and orange. What is the orange for? Also need manual.

Its like the wiring in your house. That little three prong plug. There are three wires, one black,one white, and one green. The green is a ground wire , the black is neg flow and the white is positive flow. Well the red wire is hot ,the yellow wire is neg flow,and the black is ground. Some times the yellow wire isn't even connected. Look inside your radio and you will only see a red and black wire???you will have to google the radio model as such ( 77-118 owners manual)

set your volt ohm meter to 200 VAC if you have a cheap dial one or if you have a nice auto range one, set it to AC volts and test. red to the three wires, black lead on white...

I have replaced the cooling sensor with 2 wires on my 1999 ford tauras dohc and the fans still dont come on...can someone help me out on what else to check?

89b004a0-3483-43bf-8c74-29d0d7af8fa7.jpgI'm not sure what your reason was to change out the temp sensor but guessing some diagnosing should be done before you were to purchase more parts that aren't needed. To start with have you even checked the fuse for the cooling fans. In the picture above is the layout of the fuses & Relays in the fuse panel under the hood of the vehicle. I marked the fuse that needs to be checked with a red arrow and the yellow arrow is the low speed cooling fan relay location. There is some testing in order to check that but if the fans are not working on any speed then I doubt it's a relay issue. With the A/C on or the engine hot enough, you can check the red wire with the orange stripe or the red wire with the gray stripe. Using a test light you should have power in one of those wires. The red/gray wire is power for high speed and the red/orange wire is for low speed. If no power there then you are dealing with a wiring issue. I seem to recall but would have to look but I believe that year taurus had a main box to operate the cooling fans mounted to the crossmember just in front of the radiator. I think it was a black box with a number of wires at the connector to it. In any case check your fuse if you haven't chack your ground at the fan motors (the black wire) and check for power. If no power and ground is good as well as the fuse, you can reply here or email me directly at and I can give you some other testing procedures to help diagnose it. Hope this helped....

I doubt there is a fuse on the pigtail, it sounds like your black wire is grounded somewhere. Check black to red, if you get 120 or close to it, your black is shorted to ground.

Radio works just have no digital read out on 1999 explorer. Is it fused related?

Hello! Yes It could be fuse related. You have lost power on the Blue/Red lead, which is illumination to the radio.

If you have a multimeter you can look for +12volts on this wire with the key on. If it is not present; Check fuse #27 15amp inside drivers side fuse box.

In case you ever need the entire wiring; Here it is...

Green/Yellow memory +12volts with key off

Yellow/Black ignition +12volts with key on

Red Ground

Blue/Red +12volts with key on


FR + White
FR - Green/Orange
FL + Orange/Green
FL - Light Blue/White
RR + Orange/Red
RR - Black/White
RL + Pink/Green
RL - Pink/Blue
