1991 520 H, I can't find the correct seat switch for the wiring harness. The wiring harness has 1/4" female blade style terminals in a connector housing with terminals at right angles to each other. I know what does not fit the 1991 wiring harness. It's not the micro switch. It's not the blade style switch with the blades in line with each other. There is a correct seat switch with connect housing used on the 200 series, switch fits between the seat steel pan and the seat foam, is this the correct seat switch style for 1991 520H or ???
