Hello, My name is David Brooks, I have a 1989 econoline 150 club wagon with a 4.9 inline 6 motor. my Question is what do i need to do to fix this issue? i have tried replacing all fuses. no trouble shooting guide shows or helps with this issue. online searches says it is a seat belt relay that is related to the timing of how long it stays on, but cannot find no info on google or haynes manual. is it in the ignition switch ????? and i am not going to just pull the light out.... thanks for the help.

 

There is a switch in the seat belt receptacle, check that for correct action.
