So i'm in the midst of converting a 89 Ford Scorpio from automatic to manual transmission, and so far its gone well, most of the wiring is sorted. What i need some help on, is how to do the wiring for the reverse light and speedo, and how the clutch wire should be mounted (i think i can manage that one, but its always nice to listen to advice from others) Any help would be greatly appreciated!  |

The old beastie  I really don't want to put in the wiring from the manual donor car....  The mechanical bits were easy enough to do though  Wires from autobox  Not sure if this is the correct hole for clutch wire  |

The speedo depending on what Box your using will need a VSS cable I had a Type 9 Box to my Scorpio engine
You can get such from Burton power, think it needs an adapter or owt I forget now

If you have the manual loom there, the autobox wiring has a multiplug on it that should be interchangeable. As said above, the speedo will need a VSS signal to work, so should be on the gearbox section of the manual loom anyway |

Heh, well as soon as you said there'd be a plug, i found the damn thing. Removed the autobox loom, and plugged in the manual one, no loose wires there now. Just need to change the injector plug from new to old type (or the other way around, anyway they are different on new vs old engine  And i need to get the manual accelerator cable and possibly the thing it mounts to, as the auto cable seems to be a little too short. Oh, and fix the clutch pedal and stuff... I think i'll have to enforce a "my own curse word ONLY in my garage" rule, or i'll never get curse word done on my own cars, haha Oh yeah, the engine\gearbox is also from a Scorpio, and belong together, should have said that... Old autobox shat itself, and the engine's gone 290000kms, the new engine\box has only gone 80... |

So i've tried hooking everything up, when the ignition is turned, i can hear the fuel pump buzzing for a moment, so its working, but it wont crank when i turn the key. Is there some sort of immobilizer on the auto cars, or have i just borked something up? Asked on the fordpower forum aswell. Getting a bit sick of this car, tbh!

Autos have to be in neutral or park to start, could be a stray wire that needs to be connected elsewhere when using the manual box

Its got to be related to that wiring loom that runs to the gearbox. Alternatively, are the keys/ ecus etc coded on these? Could something have got confused? You could always bridge the starter relay to see if it runs then - that would find out if it is an immoboliser problem or something to do with the starter inhibit on the ex auto box.
Your pictures of Norway road trips make the place look wonderful, all that space + no people sounds like heaven (or New Zealand)

Gave it a try, the thing starts if you short the starter with a screwdriver, and it runs a lot nicer than the old engine, even without exhaust. Bloody loud though!

Woohoo diagnosis at a distance, glad the new motor sounds a good one. Its got to be on that gearbox loom somewhere, could you test for feeds etc to try and work out what each wire does? I'm guessing but on the manual box there is probably only something from the speed sensor (if it has one) and for the reversing lights, anything else could be related to the starter inhibit.

Aaaaand now it doesnt start, it just coughs. Well, i'll give it another go tomorrow, it might just have drowned, seeing as i didnt have the lambda sensor thing bolted in. Or exhaust, for that part  |

Dear Mr. or Mrs., I would lik to know what gearbox, flywheel and clutch you used for this build and how it eventually went. Another thing that I would love to get is some tips and tricks you used. Kind regards, Victor De Nolf |

The obvious choice would be a MT75, flywheel and clutch from a RWD V6 Sierra. However I imagine they'll be very rare. You can build a hybrid RWD MT75 by using a (used to be more common) 4WD Sierra gearbox, then transfer the gear set into a 2L Twin Cam Sierra RWD MT75 rear casing, but fit the V6 bell housing.
There might be more chance of finding V6 RWD MT75's in Europe as I think some of the none Cosworth Granada's came with them from memory.

The scorpio and Granada were widely availble with the 2.9V6 and MT75 box in Mainland Europe, the German Police had a lot of them.
