adding abs to a non abs jeep
i want to put abs in my jeep after seeing exactly how bad the brakes are in the rain last night. i would assume its just install the abs pump, wheel speed sensors, and possibly have it programed. im fine with bleeding brakes and making the lines but iv never done an abs retrofit before. ideas, advice, or anything would be greatly appreciated. i see that there is an unused wiring harness in the area where the abs pump should go that i would assume is for the pump but i haven't looked to see if the speed sensor wiring is there, but i would assume it is. hearing from someone with experience in this area would be great. and please let me know if this is a bad idea, i dont want to sink a bunch of money in this idea if there is no chance of it working.

What do you mean by how bad the brakes are with non ABS? a vehicle will actually stop better with out it but you have to not get used to just jamming the brake pedal to the floor. How are your tires? How are your brake pads?

You will need everything from a abs jeep. IT would be a good amount of work. Afternoons worth of running wire.

I'm one of those who feel ABS is better on slick surfaces, hell they use ABS on commercial jets and fighter jets as well because they're all about what works best damn the cost. It'd take a well-trained professional driver to out-brake ABS, at least in my humble opinion. Anyone who has ever been in a panic stop/emergency situation has better things to do than to worry about perfect braking technique. ABS allows you to simply stand on the brakes and not worry about going into an uncontrolled skid. I had to remove my TJ's ABS because the D44 I installed had no option for it but I'd rather have it than not.

That said, it'd be a nightmare to install ABS as not only would you need the ABS computer and sensors, you'd have to install a whole new hard brake line system as well to mate up with the ABS pump system located inside the battery compartment. It's a nice thought but unless you were willing to go to a lot of work, I don't think it'd be worth it. :)

what i mean is it is hard to stop and not lock up a wheel or two if you arent very careful. braking system is in great shape. i installed brand new pads, rotors, rebuilt the calipers, shoes, drums, hardware, new wheel cylinders, ss soft lines, and all new hard lines (they were rusted and the ends were seized on the lines). tires are fine, soft and have plenty of tread. i guess ill go pull an axle and see if they even have the speed sensor setup on them before i decide if i an going to do this.

Again, you'll need all new hard lines as all of the hard lines going to the brakes come out of the ABS brake controller. Plus new hard lines for between the ABS pump and master brake cylinder. There's a maze of hard brake lines in that area.

I dont know about how to install it, I had my own close call due to lack of ABS in the snow. Thank God the driver coming the other direction saw what was happening and was on dry pavement able to stop in time.

I'm also used to ABS and my Jeep doesn't have it. Like a step back in time. I'm sure it can be done. In 1994, it was a $500 option on a pickup I ordered. Pretty much OE now. Good luck.
