Yes that is the system that I have. I am going to check some little things like fuses and relays seated properly soon. I have been working 6-7 days a week right now.

i beleive that the pump would almost run constantly.if you just got the jeep its posible it could be unplugged there is an amp looking thing under the back seat drivers side check the plug on that. it wont fix the problem but you need to see if it is the pump. lots of people unhook everything because of the noise.

Well I took the plunge and started the conversion to normal brakes! Picked up a master cylinder and booster from a 95 cherokee. Everything is done except changing the fittings and pulling the rest of the abs wires. One stupid problem is I cant find the correct nuts for the master cylinder! I have tried two different sizes, and just cant get it right! Lol, tomarrows another day....

I've been told this too. They said that they would put it in twice to try to speed up the process. I don't understand why they would stop making such a reliable engine.
