HELP! In my '70 Cruiser I am installing a '71 F engine w/fourspeed tranny and direct shift xfer case and can't find an indicator switch for the FWD. My previous 3 spd/vac xfer had one.The flat cover on the xfer case doesn't have a port for the switch. Any ideas where I might look? There's a threaded hole on the top of the xfer case, but no direct connection to the interior, it looks more like a mounting hole for another something I don't have and don't know about. And to top it off the wiring diagrams are no help. Hanging off the frame above the xfer case area are two wires, YG and GY. The diagrams show that the GY is for the backup switch, but the YG isn't indicated. I think they both go to the backup switch which has two wires, RB abd RB.
