I am looking for "base diagrams" and electrical ratings for relays type R1, R2, and R3.

Primarily for substitution: in particular, electronic parts supplier Jameco has at least half a dozen relays of this style on clearance in the $2-$5 range.

Secondarily to spoof the relay functions with the relays removed for diagnostic purposes.

I've come to understand that R1,R2, and R3 do not define fuse box position, circuit, or specific function of these relays, but instead denote the type and characteristics of the relays themselves.

Thank you in advance for any insight!
