Default 1989 Dakota ABS module...

ok.. I'm crazy.. but I can't FIND this on my 89 Dakota 2WD 3.6L LE and I know its there.. I've got the service manual and it has a diagram.. but not helping. If anyone can just u/l me a pic (or several) of where the heck it is I would be very grateful. I have a abs/ parking brake light always on problem... and after having the garage fix the no backup lights (trans backup switch).. and no a/c (relay on firewall).. the mechanic thought the abs module was the problem. Ok.. the tach works and the speedometer works.. so not the speed sensor..
Send me pic!! thanks..

speed sensor doesnt do anything for abs anyways. Pull up on your ebrake. Fixed.

Do you have 2 or 4 wheel abs?

ahh if only that was true... I've set and popped that brake more than a few times.. and pulled it up as well. Even tried to tighten the cable underneath.
thanks for the response.

2 wheel drive so I'm assuming 2 wheel ABS.

But blast... there should be an ABS electric module someplace!!!

thanks..

Again, you speedometer and tach have nothing to do with your abs unit,sensors or amything remotely related to abs.

Shame if this had to happen this didnt happen sooner. I just junked a 94 about 3 weeks ago.

Two items, both obvious from researching through the factory service manual:

1) Your number of drive wheels have nothing to do with the numbers of wheels that have ABS directly; you need to check and see if you have ABS sensors on the front wheels first.

2) For 1989, the speedo is driven off the transmission via the speedo cable; the tach is driven right off the ECU; NEITHER has anything to do with ABS. If an ABS sensor has failed, you'll still have speedo, and you would still have tach. Again, that's pretty obvious from the FSM.

Try following the brake lines to the hydraulic unit first.
