Good for you ! One less thing to worry about !
How bad can the cables be ? There can only be so many cables and most of them can only go on 1 place !
I would like to let you know something about the way the fuel pump should work though. This is how they work on the 33's and normally it should be the same on the 164 Bosch motronic as well.
The fuel pump does NOT work when the ignition is turned ON.
On the 33 there is a pink and pink/white cable plug that is connected from the ECU loom to the fuel pump plug ( if still the original ).
The Fuel pump relay will only be triggered
by the pink/white cable, through the crank sensor , when the engine is cranking or started !!!
So dont be alarmed if you dont hear the fuel pump working when you turn on the ignition switch !
Other than that it should be prety straight forward.
6 injector plugs ( they should have the number of the cylinder writen on the cable )
1 flow meter plug
1 crank sensor plug
coil could be a bit tricky , you need to check how the standard of the sprint was powered ( either a magneti marelli coil originally on the sprint or a bosch ) and check polarities . They could be reversed.
Idle switch sensor is usually blue colour, and trhotle position switch cannot be connected elsewhere.
Other than than , if you have your starter cables connected , alternator and lamda sensor, the car should crank and start !
....love doing these kind of work... I wish I was there to give you a hand with it
