...not least the distinct lack of a loom anywhere near the car. ::)
Picked up a MID, estate stalk with buttons and some other bits and bobs. Pulled the dash apart, MID has different plug on it, foiled at the first hurdle, but a moot point as there is no wiring for the stalk >:( Guessing a dead end has arrived. Put the car back together, and now the TID has stopped to work. It flashed on once when I plugged it in. Field range light comes on with the ignition but top display is blank. Was working fine earlier. >:(

yeah, you will need some minor wiring mods, as explained.
How many pins does mid have?
-
Will have to have a count int morning. ::) Plug is completly different though :-\ car has yellow plug, MID has grey. I 'liberated' the plug and a couple of inches of the loom for the MID, couldn't get any more loom than that as it was pinned behind dash :-\
P.S. What are said wiring mods? how much more loom do I need to aquire?
Should really have asked the question before I went rummaging around the scrappy, but have always been a bit premature ::)
-
Yellow. Oh. Bugger. So none of the check control etc are present. Boo. I would need to check if the engine signal is on the yellow plug...
Get a Haynes Book of Booolax, and look at pinout for both types (Haynes covers early type and later type), and wire it based on that.
-
Well some progress :y After careful studying of the pictionary book I have done the following:
1. Identified all but one of the wires on the MID loom (that I found connected to the MID :-X).
2. Cross referenced all the wires on the TID loom.
3. Dismantled both plugs and transfered all the common wiring to the MID plug.
4. Connected Pin 6 on the MID to Pin 22 on the instrument cluster (ECU).
5. Connected Pin 26 on the MID to Pin 20 on the instrument cluster (fuel gauge).
6. Connected Pin 15 on the MID to the Brake Pedal Switch.
7. Connected Pin 16 on the MID to Fuse 2.
8. Connected Pins 23 and 24 to the control stalk, carefully modified to use the later plugs. (stalk came from a pre facelift, so may put a new one on at some point).
9. Taped up the remaining 6 wires for now.
The MID works as it should except it keeps telling me to check everything ::)
The head/tail lamp wiring will be grounded. Everything else will be connected accordingly where the engine wiring comes into the car behind the glovebox. Washer level already plugged in, new coolant bottle awaiting collection/fitting. Not sure if check control module is fitted or not but that only seems to check the lights :-\
The only wire that I couldn't identify was SWGR from MID Pin 28. Not listed in the blox book. MID came from a 2001 2.6 CDX auto saloon if that helps.
-
Sounds like you should do a guide :D
Pin 28, on old TID, or new MID?
-
Was thinking that as I was typing ::)
Pin 28 on the MID 32 pin grey plug. (TID was 26 pin yellow). :y
P.S. I removed the Grey wire from MID Pin 21 as that goes to th'autobox. Pins 25,30,31 and 32 all empty.
-
MID 28 goes to stop lamps
-
Doh. :D There is a SWGR wire on the brake pedal switch... That said the 'check brakelight' message goes out as soon as pedal is pressed, so could that go to summat on the check control module then :-\
-

Yeah, there are 2 wires going to different parts of the brakelight circuit.
-
That's a relief, there isnt much space behind the dash for soldering ::) All the remaining wires will end up behind the N/S kick panel/ Glove box. :y
-
Curioser and curioser. ???
Swapped out coolant bottle for a shiny new one with sensor, knowing I'd seen a suitable plug about 5 inches from the bottle. Turns out it only has 3 inches of cable on it... easily extended, But...
The wires on it are BR (earth) and BRGN, which according to the book of blocks should be for the Oil Level switch. Guess making a section of loom for that will be the best end result ??? Two other plugs in that vicinity are squarish ones, presumptiously Power Sounder and Bonnet Switch, neither of which are fitted ::)
-
Given that my car doesn't have an Oil Level sensor (yet)...Is there any reason why I can't connect BRGN (MID Pin 13) oil level with BLGN (INSTR Pin 13) oil pressure. :-\
Thinking that if the pressure were to drop then the MID would then throw up the 'Check Oil Level' message as well as the red tell tale on the instrument cluster. :-\

I probably wouldn't. Besides, if that dash light comes on, its toast anyway...
-
Oil level isn't a significant issue, it's checked a couple of times a week and changed every 8/9 weeks. :-\
Have a feeling all I would actually do is put the check oil message on permantly as the pressure switch would be waiting for a negative, wheras the oil level would expect a positive :-\
-
Could MID Pin 17 WEGN be connected to GRGE on the centre air vent lamp circuit? :-\
-
Finally got round to connecting the MID to the ECU, now all works beautifully :y Managed to get the wire over the top of the glove box without removing it too :y
Now have realistic MPG/Range readings. Todays average is 25.4 MPG, apparantly using 0.3 gallons per hour when idling, think that would be about right for a V6 :-\
Only Oil Level and Head/Taillight wires to find homes for. If I drop the sump at some point I may as well replace it with a clean/shiny one with a switch fitted. 8)
-
So, if I understand you gyus right, if the car's TID has a gray plug, the swap is easy, and if it's yellow, it's better to change the loom???
Is there some roule that the F/L with DBW always have the gray 30 pin plug? either it has a TID or a MID?
And the check control module... where is it located??
Just some question to prepare me to the challange when the cars arrive :))
-
Can only speak for my car, which is factory built police spec. :-\ So bits of the loom don't exist either from the factory or afterwards ::) But the pins/wires in the yellow plug, (26 pins), are also present in the grey plug, (32 pins). :y The issue is that the 'extra' wires on the grey plugs might not be present in the loom of a car with the yellow plug. :y Wiring diagram in the Haynes book of variable information is reasonably accurate, most of it applies to the facelift cars, the only significant difference being the ECU wiring.
HTH, Al. :y

Right have just seen your other thread ::)
Check control module lives behind the glove box, can't tell you what it looks like though as I don't have one on my car. ::)
Well some progress :y After careful studying of the pictionary book I have done the following:
1. Identified all but one of the wires on the MID loom (that I found connected to the MID :-X).
2. Cross referenced all the wires on the TID loom.
3. Dismantled both plugs and transfered all the common wiring to the MID plug.
4. Connected Pin 6 on the MID to Pin 22 on the instrument cluster (ECU). GN.
5. Connected Pin 26 on the MID to Pin 20 on the instrument cluster (fuel gauge). BLSW.
6. Connected Pin 15 on the MID to the Brake Pedal Switch. SWGE.
7. Connected Pin 16 on the MID to Fuse 2. SW.
8. Connected Pins 23 BRWS and 24 BRRT to the control stalk, carefully modified to use the later plugs. (stalk came from a pre facelift, so may put a new one on at some point).
9. Connected Pin 27 on the MID to Pin 3 on the ECU Body loom plug. SWBR.
10. Connected Pin 20 to the Coolant Level Switch. BRBL.
11. Connected Pin 22 to the Washer Fluid Level. BRGE.
12. Connected Pin 13 to the Oil Level Switch. BRGN.
The MID works as it should except it keeps telling me to check everything ::)
The head/tail lamp wiring will be grounded. Everything else will be connected accordingly where the engine wiring comes into the car behind the glovebox. Washer level already plugged in, new coolant bottle awaiting collection/fitting. Not sure if check control module is fitted or not but that only seems to check the lights :-\
The only wire that I couldn't identify was SWGR from MID Pin 28. Not listed in the blox book. MID came from a 2001 2.6 CDX auto saloon if that helps.
Following the above you should have 3 wires left over: 1. MID Pin 17 WEGN Check Control.
2. MID Pin 18 SWGE Trailer Sensor, (check control?).
3. MID Pin 28 SWGR Stop Light, (check control?).
The MID will tell you to Check Headlight/Taillight every so often, but you should be doing that anyway ::)
Having the complete donor car with a MID, you should have all the bits you'll need except the wiper stalk as they're different saloon/estate. :y
HTH, Al. :y

Thank's :y
When I'm thinking a bit, the check controll is located on a bracket to the fan. Just had a little problems with it when changing the interior fan on my ex TD. Because I have only seen it when the board commputer MID is fitted :y Located to the left of the Auto ECU on my left hand drive car.
So if i have the yellow plug, the easiest way is to change the entire loom under the dash. i think..... :o
Have to do some invetigation when car is at sight. Make a how to tread, and if I have to do the same to mine, I will be connecting the check controll, then it can be added to yor tread :y :y
Thank's again.

No just carefully dismantle the plugs and swap the pins over :y
There is now the bare bones of a 'how to' in the Test Zone. :y hopefully it'll make sense ::)

I think those wires can be grounded or up to 12v (via pull-up resistor for safety) to stop the check control signals annoying you. Or retrofit check control ;)
