Where can I find a wiring diagram for a 91 suburban speedometer. I am swaping trans in my 85 C10 to the electronic 4l80e & bought a electronic speedo out of the 91 suburban.
eautorepair.net has the info I was looking for $12. I have since found out that the speedo is controlled by the DRAC module.(digital analog control module)Anyone have any experiance with this or know someone who has. With all the LS swaps into C10's there has to be someone whoe has ran across it.
Well looks like i now have motor problems so ill be doing a complete LS & tranny swap. Any info on headers, mounts, wiring & computer would be good.
After a new roller cam & lifters I decided to just add a 4l80e & TCI controller. Best money spent to date
