F-150 receiver assembly-remote keyless

the speedometer, odometer, keyless entry and dome light stopped working on my 1994 F-150. I was told I needed a receiver assembly-remote keyless ( $400/receiver $200/labor) to correct all of the problems. I find it hard to beleive the the keyless entry receiver controls the speedometer and odometer. Can someone verify this. Thanks.
