Where can i find a MAT (Manifold Air Temperature) sensor for a 4.0L renix cherokee?

 

If you look by your throttle cable there is a sensor on the top of the intake manifold a few inches closer to the fire wall

 

it is screwed into the manifold to the rear of the throttle body 2 wires coming out of it.
MAP sensor mounted to firewall above the valve cover green plug 3 wires 1 vaccum line attached to it.
PS forget about the D44 go with ford 8.8 easy sway 95 and newer have disc brakes and your current master brake cylinder will work fine with it.

 

Brass hex bung behind the throttle body, has two wires going into it.

For replacement, it's a standard GM part of the vintage. If you can't find it locally, you can get it from Marren Fuel Injection (www.injector.com) for a good price - you can also get the MAP (Manifold Absolute Pressure sensor) and a couple others from there as well.

You do need to adapt the termination on the IAT from Marren - but they provide a plug, and you can simply cut the tail off of the old sensor to make the adapter tail. Do it that way - so if you need to go back, you haven't modified the original wiring.

 

I can sell you one. 10 shipped.
