thanks don. i was looking for a tsb for upgrading the cps.
i found it this morning at( another freaking jeep site ), i had bookmarked.
the part # is 83100066, and its now called, a ckp sensor and harness. it plugs into the ecm. thats what i had read about but couldn't remember where. dave
by the way, if you are looking for the connector that plugs into the renix ecm it is a gm part # 12146448. they are .35 a piece. the pliers to close the connector of this type is $21.00.
