911 DME Relay

Fellow Pelicans,

I am helping a buddy with getting his 1980 SC running that he recently purchased as a rolling shell. We have come across an issue with the ECM relay where the wires have been cut and we cannot find a wiring schematic online that shows how to wire it back in factory form. Does anyone have either the wiring schematic to share or a photo of a wired ECM relay for an 80-83 SC (K-Jetronic w/out lambda and no acceleration unit). We are at a dead end
