Mi16 Loom Going Into A 205 With Early Phase 1.5 Engine Loom

[smokey 0]

Hiya Guys

 

I know this has been covered in the past with phase 2 looms and there are lots of guides, but there really isn't much info for connecting a Mi16 loom to a 205 with a phase 1 or early phase 1.5 loom. There was one thread but allot of the picture links have died.

 

My CTI originally had a phase 1 engine loom and dash loom.

 

I stripped all of this out because i wanted to put a new dash in (old dash had had it) so i put in a phase 2 dash loom and got hold of a phase 1.5 engine loom with the belief that it had the 2 brown plugs so i could follow the guides on here and connect it to my Mi16 loom.

 

The Mi16 loom i have came out of a converted 205 so it already has the link loom with the 205 brown plugs on.

 

I currently have the phase 2 dash loom and 1.5 engine loom installed and connected to each other via large brown mulitplugs in the fuse box area.

 

So i was set to connect the looms. The trouble is there wasn't any brown plugs in the drivers foot well, where i was expecting them.

 

Instead i have this:

 

 

From what i have been told this will actually connect to the Mi16 loom

 

In the engine bay i still have the original 205 phase 1 ignition coil

 

 

I was wondering do i still need this?

 

Also in the engine bay are the old 205 sensor wires (i think)

 

 

I was wondering once i've identified which these are can i wire these to the 405 link loom or would it be better to trace these back into the car and do it inside?

 

Thanks Guys

On a Phase 1 just use the existing 205 sensor wires, and then it's just three wires to connect up - 12v ignition (from the connector fitting the coil/ignition amp), fuel pump (from the tachymetric relay area) and rev counter (from the coil).

Ok cool will do it that way. Wanted to use all of the 405 loom, but doing it this will make it loads simpler!!

 

I dont have a tachymetric relay on this 205 engine loom. I did on my old phase 1 loom but that gone now.

 

What about the ignition coil?

 

Thanks

Hiya Guys

 

Had some success yesterday with some of the sensor wires.

 

I've hooked up a nice new car battery and found the following by earthing them.

 

Oil Pressure

Oil Temp

Water Temp

2 of the other wires made the Stop light come on.

 

The others did nothing. But i know some of these will go to the starter motor and alternator so thats probably why. Not sure which, is there a way to tell?

 

Also in this picture i have the old 1.6 phase 1 ignition coil

 

 

My understanding is that i dont need this as i have the smaller ignition coil for the MI which is bolted onto the inlet manifold.

If i dont need it, what do i do with the wires? Do these connect to the 405 mi loom?

 

How ever i will need the ignition amp. Just wondering where do you guys tend to fix yours? Mine is currently attached to the coil backing plate, seen in the background of this picture:

 

 

Was also getting a warm smell coming from the steering column, so thats coming off again today to see whats up.

 

Thanks Guys

Ignore all the original 8v coil and ignition amp wiring - this is redundant with the Mi16 install.

 

On Phase 1 cars, the 8v coil and ignition amp wiring is on a seperate mini-loom that connects to the main loom with a single 2 pin white plug which hopefully is there on yours as well - just unplug that and ditch that part of the loom and the coil, although the ignition amp is the same as an Mi16 one (assuming it's a Bosch item) so you can retain that if you know it's good.

 

IIRC the two thick green wires that go to the coil are for the rev counter and for the fuel injection ECU timing pulse - both are redundant when you go Mi16, as the rev counter feed is from the Mi16 loom, and the ECU uses the crank sensor for timing instead.

 

I've not personally seen one of these very early Phase 1.5 cars with the Phase 1 style wiring, but I'm assuming that it's loosely the same setup as a proper Phase 1. Assumption being the mother of all f**k ups though, treat this post as a hint rather than a gospel guide.

 

As for identifying the starter and alternator wiring - the alternator wire when grounded will light the battery/charge light on the dash, and the starter wire is normally a little thicker and will get 12v when the key is turned to crank but be 0v otherwise. On Phase 1.5/2 wiring it's wire 46 (light blue) and wire 7A (brown) for the starter and alternator respectively, but I can't remember off the top of my head if this is true of Phase 1's.

 

The two STOP light wires you found will be oil pressure switch and high coolant temp switch - the oil pressure one will illuminate oil pressure, STOP and high coolant temp, whereas the high coolant temp one will only illuminate STOP and high coolant temp on the dash.

I have seen one Ant, Tachy relay up with the ecu but the separate ignition and gauge wiring and single brown multiplug, was an E reg 1.6 with full Phase 1.5 trim and bodywork.

 

(you will need one of those coil wires to drive the tachometer/rev counter I found, but It was a 2.0 conversion I did and simply used it for ease of converting it back to 8 valve if needed)

Hey guys

 

Thanks for replying.

 

The 8v coil wires seem to be hard wired into the engine loom so cant unplug it. I know what you mean though as the old phase 1 loom I had in the car did connect to this via a white 2 pin plug.

 

Yeah the ignition amp is a Bosch one and going from Sartys ignition PDF its the same part number so all good there.

 

So going from this picture:

 

 

Will any of these be connected to the mi loom or will I just need to tie them back?

 

The thick green wire from the coil goes to this plug:

 

 

So not sure which one i need to connect to the mi loom, or could it be either? That plug also has the fuel pump wire etc so was going to hard wire these into the mi loom from this point.

 

As for the sensor wires, i guess i would be better off using the 205 8v ones? However was going to use the ones on the mi loom.

 

Could i just then wire the 205 8v sensor wires to the mi loom where there black/brown plugs are? That way the mi loom plugs into the sensors and then feed to the old 205 sensor wires and thus to the dash?

 

Thanks
