ELECTRICAL SCHEMAS CAPOTTE XR3I CABRIO

Hi everyone!
I have a 1990 XR3i and the problem I'm having is that the electric convertible top isn't working. The motor works because I tried powering it directly, but the switch doesn't work. I was wondering if anyone could share the wiring diagrams or tell me where I can find them, as I've been searching and haven't been able to locate them anywhere. Or if any of you have experienced something similar and could lend a hand, as this problem is driving me crazy.
Thanks so much!
