I'm having a problem getting my chip to work on my 99 Expy, and posted a message below asking if anyone knew of why it wasn't working. With the chip in I could not start the car and I got a rapidly flashing Anti Theft (PATS) light on the dash as well as the odometer reading (------) instead of the cars mileage.

openclasspro gave me a link to motorhaven who's FAQ had this paragraph in it:

Any known problems?
If you have a vehicle between the years 1998-2000 there's a very small possibility that you have a vehicle that requires two jumpers to be soldered into the computer. There's a random handful of computers which the service port (where the chip plugs into) has been disconnected. This doesn't allow the information from the chip to get to where it needs to. Usually when you're trying to start the vehicle with a chip installed your Anti-Theft light flashes real quickly (Diablo and Superchips both offer a free jumper installation service). The small possibility that you may need this jumper added needs to be considered if you own one of these years and you purchase a chip.

That makes perfect sense as I'm one of those folks who is doomed to die from a random asteroid hitting the earth right where I'm standing some day. The burning question is...

Does anyone have instruction on how and where to solder the jumpers, and if there are any pitfalls in removing the PC card from its aluminum housing to do so.

I'm pretty experienced at electronics work, but it always helps to hear from someone who's done it on the particular part already, so that I don't fry my $$$$$$$ EEC box.

 

First, let me forwarn you that the two spots are very small and close together. You'd better have a desoldering iron and iron with a very small tip.

Here are photos:

These are from Motorhaven (the store that pays for this Ford Truck Enthusiasts site to exist) and as far as I know there aren't any detailed instructions out there for this. We usually setup setup installation the jumpers for our customers, not all dealers provide this type of service (if your dealer is experienced they should have known about the jumpers the instant you told them about the theft light).

 

Ken,

Thanks for the pictures! They'll be a lot of help tomorrow when I perform EEC surgery. I've got access to all the equipment I need at work, so my lunch hour will be spent doing some soldering if I don't hear from the guys I got the chip from before then.

To clarify if you could, the first picture shows location for two jumpers just above the card connector.

The second picture shows loaction for two additional jumpers to the left of the connector labeled W243A and W244A.

The third picture shows a different card style than the first picture, but essentially the same two jumpers.

The fourth picture shows the back side of the card where the jumpers from the second picture are located.

The fifth is a finished product view.

In all I'll be installing 4 jumpers on the pc card. If this is not correct, please let me know.

I really do appreciate the help, especially as it puts nothing in your pocket but my thanks.

To be perfectly honest, I went with this shop for two reasons. 1. becasue the guy who did a TBird chip for me in 97 did a really nice job both in knowldege and service and, 2. they gave me a really nice trade in on said chip. I think the company is now run by some other folks. Hopefully with the weekend closing I'll hear from them and since they're local they SHOULD tell me to stop on by and they'll make it all better in tomorrow morning's email. We'll see.

 

Ken,

It seems that PDQ needs to add another picture to their jumper instruction collection. I'm lucky that way....

Turns out my EEC didn't look like any of the ones you showed me (same as on PDQ site). The local tuner here said that mine is a mustang style EEC. Makes no difference since the code was correct, but the jumper points were different. They were two sets of large rectangles on the back of the board. He said he's seen these in trucks before, but its unusual. The bright side is that the jumper pads werent the tiny ones usually found, so installing jumpers was a lot easier.

Anyhow, thanks for the help and the forum!!!

 

There are actually several different computers not shown that have missing jumpers. Matter of fact, any type of Ford PCM from 1998-2000 can have it missing. The photos were there to show examples of the missing jumper(s).
