Tranny Gauge Question

[no-tel-in]

Hi, I am going to be installing a trans gauge in a '94 E-350 (gasser 351) with the e4od, is there a test port on this trans like my 4r100? Also where can I pick up power for key on for the gauge. And power for the light with lights on?

Thanks in advance!

There is a test port in exactly the same place as a 4R100. They are about 95% the same transmission. The power on an E-series can be taken from one of the yellow with green tracer wires going to the ignition switch behind the panel below the steering wheel.
