looking for it as its wired to my speedo and i need to tie this trans into it, but im not a 4l60 aymore
 
well my car was originally wired for a 6 speed, the wire in the dash goes into the harness, where would it go then?

To the pulse generator, located on the extension housing. (note: depending on the year, not all 4l60e transmissions have a reluctor ring on the outputshaft.)

i understand that. my gauge is wired up to the harness that originally was plugged into a t56 and worked, the gauge shows the 217 miles he put on the t56, now its got a th350 in it, with a speedo sender unwired. I need to find out which wires in the factory connector I need to tap into, that is all
