I know that the full time four wheel drive with the np203 transfer case could come with the under the dash blue lock light, but does anyone out there have or know for sure if this light was an option for the 2spd part time NP205 transfer case ? if so where and what color wire or plug does this wire go on the part time 2 spd NP205 ? Thanks oem78

 

a black green wire comes from the fuse box to the light and a blue wire goes to the transfer case the case is put in gear it grounds the wire and turns the light on my truck a 78 orignal 205 had this blue wire in with the harness for the rear brake lights, turn signal, reverse and brake warning lights but wasn't hooked up to anything and none of the other wiring is there and I don't see any were on the 205 to hook it up its a black conector about 1" round right below the driver seat on the frame
