How do i install a centrodyne silent 610 into my 1997 crown victoria? I'am looking for manuals but can't find it, Can you please help me please

If you type in the address bar, "1987 Ford Crown Victoria wiring diagrams" you will get multiple hits. Most of the time a collage of photos and wiring details will appear and you just click on the one that looks best. Just use the search feature

Did you already Google this one? looks to me lots of owners did post about this. I do not understand enough to help you, but please use the words in Google and see what comes up.

...Look up "Crownvic.net" on the internet. This site is specifically for fans of the Crown Vic, and has all kinds of easy to navigate repair info. You may also type in your question and you'll probably find answers to your issues and even photos from those who have accomplished the project you have in mind. You also should check out a local auto salvage yard that has a few of your car models. Take your tools...and explore! Take off a rear door panel of The Crown P-71. Take a look at how the door control rods operate...and use your wrench to become familiar with removal and installation of parts. This is a dirt cheap education! Have fun.

Try posting this on craigslist

i have a 99 crown vic suvillan and i cant find the ambient air temp sensor where is it please help

Call Lee at Centrodyne he will help you.
The pulse is most easily found on the transmission at the VSS output. It is a connector with two wires, you want the DG/V. Run that to the pulse divider green wire. From the meter, tie the white in the 2 stand cable to the pulse output. Hook up power and ground then calibrate the meter. You should end up in the 33,000 range for calibration.

DID YOU CHECK THE FUEL PUMP SHUTOFF SAFETY SWITCH ON THE LH/DRIVERS SIDE IN THE TRUNK & MAKE SURE IT IS DOWN ,& EVEN IF IT IS SOMETIMES YOU CAN TAKE SOMETHING & PUSH IT UP & THEN PUSH IT BACK DOWN & IT WILL CRANK,& BELOW THAT SWITCH IN THE TRUNK IS A FUEL PUMP DRIVER MODULE ,IT MAY BE BAD,THOSE ARE A COUPLE OF THINGS THAT HAVE WORKED FOR ME ,& THATS PRETTY MUCH ALL I DO IS WORK ON FORDS, & LX CROWN VICS & P71 POLICE CROWN VICS WHERE I AM WORKING, HOPE THAT IT MIGHT HELP YOU FIX IT.

look under the hood in the big fuse panel and look for High beam headlight relay the relay is more than likely bad

The fuel filter is located under the vehicle on the inner side of the left (driver side) frame rail.

Should look like the image below:

Yes...parts should run between $30-$60 each...Complete arm is about 3X that much. You can find install instructions in just about any repair manual, sometimes even with parts. (depending on mfg) Any problems installing someone here will surely help!
good luck
