I just went through this here with someone else, probably yesterday.
The Nippondenso used in the Dakota and ZJ is not
a direct drop-in - the 89 uses the internally-regulated
Delco CS-130. You'll have to add a voltage regulator and modify your system's wiring to make it work (not impossible, but there are easier solutions.)
Easier solutions include:
- Finding a CS144 that will fit. I don't have a donor list to hand, but if you search "CS144" or "Delco CS144" on various Jeep boards you may find your answers.
- Finding a higher-output CS130 and swapping the front case (so you get the proper mounting)
- Taking your CS130 to a competent shop and asking them to rewire it for you.
- (Maybe) Go to the parts house and buy the 100A version if your alternator.
Why is the last one a "maybe?" Because I don't know which alternator you have now. The RENIX rigs (1987-1990 w/AMC engine) used the CS130 in three different ratings - 61A, 80A, and 100A. The 61A is the "base" alternator, the 80A is the Laredo with power goodies, base with tow package, and base Limited, and the 100A is the one for "all the fruit."
But, any competent shop can upwind your Delco for a nominal fee (probably works out to about $1/A, give or take) and extend your capability.
However, unless you get stupid with the lighting (in either quantity or individual wattage,) you'll probably be just fine with the stock or the next rating higher (unless you're going to use a winch - a lot
- the 100A is plenty for adding several electrical goodies.)
People, one more time:
The Nippondenso is only a direct swap for 1991-up XJ and MJ.
Say it with me now: "The Nippondenso is not
a drop-in replacement for the Delco."
I've had to correct this so many times it's starting to make me itch. Pay attention to the model year - or, if it's not given, ask
. Stop Putting Out Bogus Information (SPOBI,) and we'll all get on fine.
Or, you're going to end up with someone being pi**** at you for telling him the wrong thing. Not strictly your fault - except you didn't verify application before giving parts information (I wasted three and a half years behind parts counters - I saw it happen far more than I'd care to talk about. The cause was invariably either the counterman didn't verify all of the application information, or the customer didn't know what he was doing and "didn't think it was important." Even odds - both avoidable.)
Battery cables? Link in sig. All of my customers, so far, have been very happy with my work.
