wiring diagram, and trans,speedo change over
 
I have looked and looked, a few days ago I saw a thread that showed how to change a electronic to cable, (or other way around) speedometer gear on a 700r4 ( I think). and a while back I saw a wiring diagram for the engine comp. for a 80s silverado. I can't find them any where, maybe looking in the wrong section. any help ? thanks, guys Art

The GM wiring diagrams for all 73-91 except 1984 are in my sig. Maybe someone will chime in on the rest.

what year truck do you have

not sure i understand what your asking


700r4 will have a cable driven speedo... but you can also get a special gm speedo adaptor that fits in the trans and gives a electronic signal in addition

cop cars had these adaptor

then there is also JTR jag that run ... are you running and ecm ?
