Yeah, but the factory setup does not deliver a full 12v. This where the MSD
will help.

>>By the way...I was looking in my manual I am was curious about what it
listed
>>under the ignition chapter:
>>Ignition Coil Resistence:
>>*Primary
>> 87-90..................1.34-1.55 ohms
>> 91 and later..........05-1.2 ohms
>>
>>*Secondary
>> Prestolite Coil.......9,400-11,700 ohms
>> Essex Coil............9,000-12,500 ohms
>> Diamond Coil
>> 87-90..............15,000-19,000 ohms
>> 91...................15,000-19,000 ohms
>> 92 and later.....11,300-15,300 ohms
>> Toyodenso Coil
>> 92 and later....11,300-13,000
>>
>>What does it mean or what is the difference between primary and secondary?
>>What kind of coil would I have in my 93 Dakota V6 4x4 or how would I find
this
>>out, since there is a choice of 4? I am just trying to figure this whole
coil
>>language/terminology out before I buy an aftermarket coil! THANKS ALOT!!!!
