Hello. I have bought a non-running 1994 Y60 with EFI. - I think this is the TB42E (?)
The CAS connector plug on the wiring harness has been removed, so I found a replacement plug from a Ford harness that needed very little mods to fit very nicely. This is the same distributor. 77483
Now after many hours of searching WSM's and manufacturer info etc I still have no clear info as to which pin on the CAS is which. It's that simple. The four wires are: *Switched B+ [ign rail]. *Earth. *2 different pulse signals.
I have the diagram so the wires are easily identified. Most diagrams show that they go to connector slot number 1,2,3 or 4, but I can find nothing to guide me as to slot numbering which of course, depends on the orientation of the plug and the viewer.
The previous owner fried the CAS by getting this part wrong. I think I may have done that too by assuming that the pins were 1 to 4 from left to right when looking at the harness side of the connector with the lock tab at the top. The new CAS gave no 5 volt signals on a bench test when wired this way. I simply need to be sure of the pin numbering. Easy - right?
Well I hope it is for somebody on here because I am unable to find a simple pin out diagram for this connector, and I like to think I'm no novice at searching for such things. It would be wonderful if a member could help in any way.
