compatiblity for 96 caravan flasher mod and arm

hi i called my local car place but they couldnt tell me if the 2 items i looking for are in any other years
but wanted to know if the flasher module from 91-95 works and also the control swtich at the steering column

as he cant get me the 12 pin relay but can get a 9 pin relay at 78 bucks and a control switch for 125

i wanted to bypass but wanted to know if the 96 flasher module work in the older vans so i can test it to see if it works or not


as i guessing no way i can test it to see if its working

when i search online for a flasher modular i only find the standard 9 pin but this is 12 pin so i lost? whas the other 3 pins for
