300SL-24v help please 1991

Got problem with remote key fob not working! Changed batteries, can see LED light up on FOB but not working to open doors etc. Tried re-sync' the new
batteries as written down in manual - no luck! Also, on same fuse is boot light which is not working!! Bulb checked OK, fuse replaced, no change, is that a clue maybe? Where is the IR sensor/control unit?
Lastly, has anyone have access to electricial wiring diagrams for the 300SL-24v please? Willing to buy if reasonable price. Thank you very much for any help out there.....
