Speed Sensor pinout

I'm homing in on no speed sensor connection being the culprit in my loss of power on my '68 F250/2005 HPCR conversion. I'm going to have to take out the seat, carpet and tunnel to get at the wiring to see what the problem is. When I do I want to be armed with information. Can anyone tell me what color the speed sensor wire is in the loom and what 'arm' it takes from the ECM down over the top of the bell housing?

So we found two problems - a set of wires squashed between a bold and a mounting bracket and a broken ground. But none solve the rev limit problem. We traced the Speed Sensor all the way to the ECM harness and could see no problem. It must be something else. We are getting a code for the governor on the 48RE. Could that cause this kind of problem?
