i took my ride to the ref today, and he is asking me to instal an ecu from a 1995 truck with a manual tranz. this is to get around installing a smog pump. ive been to several auto parts in town and they dont show any difference in part #s for either...wtf? does any one know if there is a specific ecm for a 95 with mt vs. at? i am currently running an ecm from a 87 . i am also looking for a vss (vehicle speed sensor) that will adapt to my application???????
