Hey Rog

Hope you can help me with somewiring issues...I have an Early AUDI 2.3 20V 7A HITACHI ECU this are the numbers that are vissible on the ECU (893-906-266B) (MMS-04B/ D3-03856/) (From an Audi 2.3 electric injetion with a Ballast resitor... my main area of help is to identify the trigger wire"colour code" of the injectors...I have made some research to minimise a lot of work in identifying the color codes, but I came across two or three diagrams that point the same direction but not quite convicing to my speculation,

The first diagram Source: 404 Page Not Found

***(file:///C:/Users/Lion/Downloads/fig02%20(1).pdf)***

The second is original from Audi Schamatics Manual (Audi 80, 90 Current Flow diagram ( page 97-5072/73/74

I appreciate any possible help and clarification.

The main issue here is very unique, this time I do not have current flowing to the fuel pump from the the fuse box, I have tried to bridge the two big connections and nothing happens. The fuel floater does get current as this is visual on my instrument cluster. So this is what I have achieved so far and rather not to mess up with a lot of things, I decided to run back and recall your utmost knowledge about the problem I am facing. Having diagnosed the fuel pump relay with the number 214, that is problem number "1" ruled out...Fuse number "13" checks out, (two fuses 10 and 15 Amp ) under the orange plastic cover, thet too check out...The only Relay I could not identify is the Alarm/Fuel cut-off relay...where or how to allocate it and what to do with it once I find it....
