I've read up as much on this here as I can. Last weekend, I scored a complete '96 XJ for parts so I can convert my '89 to non-ABS. I've got the booster/master cylinder and the pedal assembly out of the donor truck, and I have a few questions for anyone who has done this swap.
1. Vacuum line for the brake booster. The intake manifold on my '89 does not have a fitting where the one on the '96 is. I found another port on the manifold that's capped, but I'm not sure whether or not I can use it.
Line on the '96:

2. Proporitoning valve/connection. The proportioning valves look exactly the same, just that the one on the '96 is turned around the other way and the one on the '89 has the hole on the end plugged. I was looking at the electrical connector/switch(not sure what it's for) look the same. Is it safe to assume that I can simply plug in the wiring in my '89 to the same place on the new proportioning valve?

3. Brake light switch. At least that's what I think it is. The switch attached to the pedal assembly out of the '96 looks different than what I recall seeing in my '89. Unfortunately it's Monday, and I neglected to take a picture of the switch in the '89, but I am pretty sure it(and the electrical connection) are different. Any tips on this?

4. Hydraulic components. It looks to me like my best bet is to just swap over all of the hard lines from the '96, as they should(feasably) go right into place on the '89. They look like they'll all be easy enough to remove from the '96, which is good, because I don't want to have to go through bending and flaring new lines if I don't have to. I already picked up new front and rear hoses('95 TJ, I believe) to go along with the swap and my recently installed 2" BB. I read something about the rear wheel cylinders being different. Is it 100% necessary to install the non-abs units?
5. Electrical stuff. There is an extra connector on the side of the reservoir in my '89(I assume for fluid level warning?) that the '96 does not have. Can I simply leave this disconnected? And how do I go about making sure the ABS light isn't constantly on?
Connector on the '89:
No such connector on the '96:
That's all I've got for now(though I'm sure I'll have more later). Any other tips or pointers would be great. I'm trying to photo document this as best I can so others can view this later. The more information available on this swap, the better.
