I have swapped my idiot light cluster in my 91 MJ for a full guage cluster from a 93 cherokee. My problem is the sending units. I have tried autozone, autovalue, and napa and non of the sending unit they have specified for the 93 will work with my plugs. My oil temp plug has a single spade terminal and the 93 sending unit has a pin terminal? The plug for the coolant temp is also a different shape than the one in my MJ... What gives? I have tried several diff. years and both MJ and XJ, no luck... Anyone? Thanks, Judd
