5.3 swap into 91 ecsb wiring????
I put an 02 5.3 and 4l60 in my 91 chevy was wondering if anyone could shine some light on my speedo wiring. I want to use the factory speedo but don't know how to wire it up to the speed sensor that works on the new motor tranny combo. I would appreciate any help.

I found the pin out for the 95 we did. Pin out for the gauge cluster. You will find the speed output from the PCM on plug C100, pin D (DK GRN/WHT 817 Vehicle Speed Signal)

I'm using a Garmin for now! My 94 speedo was acting up when I started my swap, stepper motor is out...
