Hi Everyone,

Over the last week, I have been installing a double DIN stereo and component speakers in my pickup and my truck has been tore all apart. Finally got around to putting the dash back on, and I had the stereo going with the key in the on position, when I did the deadly DP sin, I reconnected my f5 controller, and I realized it shortly after after making the connection. I am guessing I have a fried PCM, as the truck now acts weird when you turn the keys on, sometimes even making the wipers cycle once.

How screwed am I here?

 

Errrr, well just to trouble shoot can you go get a PCM from the junkyard and try it? I know they are easy to remove, so maybe you can start there. But it does not sound good. speaking of sounding good, how did the stereo install come out?

 

most likely its fired, had the same problem with a ts chip didn't realize key was on

 

I don't mean to take over, but I am new to this and plan on getting a DP tuner. What is the issue with having the key on or for that matter in the ignition when messing with the tuner? Sorry for the Hi-jack

 

Have you tried to take the chip off your PCM and see if that makes a difference?

 

Wow, thanks for the quick responses, I feared this. By the way, the stereo is sweet, I had to trim my doors to fit 6 1/2" speakers all around, but it was worth it. I was just really excited to get my truck back on the road, but I ended up prolonging it!

Any good places to find a early 99 PCM, AWA3?

Haven't tried chip removal yet, could I have possibly fried the chip and not the pcm?

 

if the key is on when u plug the chip into the pcm it will short out and fry the pcm or chip or both

 

Good infor to know. I am assuming that information will come with the tuner?

 

i paid 400 thru ford

 

Give Hucka1a a PM, he had one,not sure if he still does or not..... I just noticed that you have a 6sp his is auto

 

yes it will come with the the directions

 

ok thank you, back to you foxracer800

 

Cardinal Rule - DO NOT have you key is in the ignition in any position (off, accessory, on, start) when messing with PCM or tuner. Whenever you mess with the PCM, have the keys on the work bench.

 

Right on Chris, I appreciate the info. Just know I am no machanic, I am only a paper pusher. Thanks for the info.

 

There is a great video of the install here:

It says at the beginning to not have the keys in the ignition at all, i knew this but was a little to excited about the new stereo.
