Problems with A/C

I'm having trouble locating a A/C clutch cycling switch for my 90 D-150 318 truck. I'm posting a picture of what it looks like, but this one does not fit my truck. Just for reference. Maybe one of you knows or can find who sells one. Thanks

I got mine at the dealership.
If I remember right mine only had a 2 wire connection instead of that 4 wire connector/
I have a 92 diesel and mine would cycle whenever I hit a bump. I actually had to hit a bump to turn it on again:wack:
