speedo cable.


I have my dash apart on my 75 f-250 there seems to be a white clip over the cable. does that hold it on or does the cable just thread in. I also am wondering how my gas guage is wired can any one give me a rough idea about where each wire goes from the guage to the sending unit etc. thank you.
The white clip holds the cable to the speedo head, once the clip is released (push in on the clip and pull) the cable itself will slide right out. I usually use white lithium grease when re-assembling the cable back into the housing.
