Help, Audi 80 TDI Injector Pump

Hello very good, I comment on my existential problem, hehe.
Well, I have an Audi 80 19 TDI of 94, they have given it to me, and it has a failure, that I know what it is but I need a little help. Well, we have the injection pump? to which 3 cables arrive, the problem only has one connected, above and where the other two go, if someone who has a car just like mine would appreciate if he could take a look and tell me where they are going.

Thank you very much in advance and a health
