Mi16 Loom Salvagable?

[East_Hud 7 1 Cars]

Hi

 

I have also finished my track car build but as many have I am stuck at the wiring stage. I got an mi16 engine loom with it but have been told it has been butchered and is not worth trying to rescue.

 

Could I get some opinions as to whether you guys would agree? It appears some plugs have been cut.

 

 

Plugs on there:

 

 

2 wires near ECU plug

 

 

ECU

 

Middle Parts

 

 

 

 

Any help advice would be greatly appreciated. Is it salvagable?

 

 

 

Cheers

From what I can see at a glance, that doesn't look too bad and I can't immediately see why that wouldn't be fairly straight forward to put right. It's not like it's fire damaged or been hacked in half.

 

The only thing I'm struggling to make out is the ignition side - coil plug and ignition amp. Are they there?

 

Given that I can't see the original 405 brown plugs at a glance, do I assume that somone has converted that previously for 205 use (or got part way through doing so)?

Hi Ant,

 

Yes i got it from a guy that had it in a running 205 already apparently but I am now starting to doubt this!

 

Which part were the brown plugs attached to originally?

 

Re coil and amp plug..i dont know tbh i thought they were in the middle in the picture with my smart hand?

 

Thanks Again, sorry for ignorance I have searched lots!

The coil plug will be a 4 pin brown plug that's a different style to the others, and the ignition amp plug will be a 7 pin plug similar in style to the others on that loom (eg #4). These should be towards the right hand side on the top picture, but I can't see them.

 

If these are missing then it's certainly a bit of a pain, but not insurmountable (depending how far back they've been cut of course)

 

The original 405 brown plugs where it joined the rest of the car loom would have been somewhere bottom right from memory, but if it had been in a 205 these would have been removed as part of the conversion.

Cheers again Ant. Need to have a good think as I dont want to pay £325 to get it sorted.

Maybe you can try Autodata to see where each wire goes (they should have numbers on them).

 

Just hook it up and see if it works, in theory each connector will only fit in its right place.

 

Haven't played with the standard ECU setup in two years so my memory of things is a bit rusty but here goes: No 1 will be injectors, batch injection so order should not matter and Supplimentary Air Device (gray plug) , 2 diagnostics, 3 unused, 4 AFM?, 5 Permanent live, 6 Flywheel speed sensor, 7 water temperature sensor.

 

Looks like you're missing the ignition amp and coil plug to get the engine running. Do not forget to connect up all earths, never ignore earths!

 

 

There may also be relays that feed the coil and injectors, those need a switched live I believe to close, but may be confusing management versions here.

 

Good luck!

Cheers for that.

 

Re the missing ignition amp and coil plug are they likely to be the two wires by my thumb in penultimate PIC?

 

Thanks again

Though thinking about it they should have more than 1 wire each.

 

I hate f****** wiring! Ha

As Anthony said, the ignition amp will be a 7 terminal connector (4 or 5 wires connected though) and the coil plug should be a 4 terminal roundish connector. You can't miss them if they're there.

 

It's easily salvageable, you just need a wiring diagram, multimeter with a buzzer, soldering iron, heat shrink and some spare wire and connectors. I've built a whole loom from scratch in two afternoons, but as with everything electrical, a good wiring diagram is key.

 

6 may also be TPS, but put up some more detailed pics of all the connectors.

 

EDIT: And here you have a wiring diagram. At a first glance 103 will be your coil, 105 the ignition amp.

Awesome. Thanks
