OEM+ Coupe 16v (1.8t on the way)

[Val]

- why no OBD pins from your ECU
- why no MIL from your ECU

- ECU connector C pin #12
- don't have it
- RPM signal either from ECU connector C pin #10 or T10M/2 (blue/green)

Edit: didn't see excel file on previous page

this helped me with my 1.8t swap

also autodata has pinouts for the ecu, pretty sure green/black was the wire colour for diagnostics port, and it just needs 12v and an earth after that

got vagcom working nicely on my 90

Ahh yeah - could be one of those ECUs that just uses K-wire... I have annotated the spreadsheet again.

I have got hold of a later style (1997) ECU and loom with only 2 large plugs that go to the ECU. Im not using the earlier 95-96 5 plug type.

97 paul

Sorry to be ****. I need the actual date stamp. Saying 97 could be MY96 for instance or even MY98

oops sorry my bad.

On the white labels there are a couple of different dates

T10 has - 04.12.97 & 03 or 09.07.97

T10m has - 09.07.97 & 12.11.97

Hope that helps.

Got my head around how to wire up the fuel pump now, gona put some words down a bit later if you wouldn't mind checking it for me pls

Fuel Pump Relay

Is this correct Paul?

I can use existing relay making the connections as bellow?

Connections -

1. BS on CEP to ro/bl T10z/6


2. O on CEP to 20A fuse (placed in an aux fuse position at fuse box) to ro/gn T6z/4


3. 87a on CEP replace 0.5 gn/sw with 2.5gn/sw to S25 (replace 5A with 10A fuse) then to 2.5 gn/ge T10z/8

lol hope that makes sense.

Will check your words later but looks encouraging.

Btw - that date is for an My98 car. This might explain the few loom differences - will look at that again soon.

1 - yes

2 - yes, but you could also insert a new fuse in the main fusebox for this... should be some spare positions in your ACE motor

3 - yes

I have been using the later set of diagrams you have on your site for the 94 coupe ACE C49, this may be wrong, I have noticed very few differences but there are some.

Just remembered about this too... C49 is for July 1994 onwards i.e. MY95

If the ACE engined car has 'R' in the VIN then its MY94 - so go with B71 as best schematic to work from
