Alternator swap questions

I have an 88 yj and just swapped in a 92 engine
Im having some trouble with the alternator wiring,

should I use the denso alternator from the newer engine?
if so how do I wire it in.

or should I use the older delco?
If so how do I change the pulley

I have brackets and wire harnesses from both engines.

The delco/cs-144 can be made to work, but it's not easy. Your voltage regulator is in the ECM so without the proper alternator you will most likely get a check engine light. I have read threads about hacking the wiring with a light and/or a resistor in the circuit but it seems like an extra headache

Oh sh## I didnt see he swapped in a 92!

If you just swapped the engine then it is still like I said. You use the CS 144. The TBI engines and all the 4.2L were all internally regulated and you need the CS 144. Jbolty is right, if you have the 92 harness and computer then you need to use the Grand Cherokee mod!

98 grand cherokee is the alt. Also a 98 durango with snow plow package. Make sure you get the optional one because standard was the same 90 amp we already have. Should be about $130 new at Advance Auto

I have also discovered that a 2001 GC limited has the 136 amp alt we use as well.

1995 YJ. 2 inch BDS Spring lift. 1 inch shackle lift. 1.25 inch JKS Body Lift 33x12.5x15's. Engo 10,000 pound winch.

The 5.2l zj grand Cherokees also come with the 136 amp alternator usually. They r the older square type grand cherokee. Just count the number of rings on the alternator pulley, if it has 7 then that's the one u want. The 100 amp and the 75amp alternators have 6 grooves on the pulley.

sorry I did not make myself clear,
i kept the TBI, and have it set up with the serpentine belt system.

Im thinking the easiest thing to do would be to put the serpentine pulley (from the denso) onto the older delco alternator. that way the wiring wont be a problem.
would the denso pulley fit on the delco alternator?
would everything line up?

Yes you should be abke to swap thw pulleys and that would be the easiest way since you stayed tbi.
