Here's the thought -
I'm thinking about the harness wiring between each wire to each sensor.

I have torn down a few engine harnesses to expose the individual wires.
Inside the harness you can see a few points where wires are joined together. Mainly this applies to grounds. My guess (never investigated) is that some sensors share grounds.

If you open up the under-dash harness on a DX you will find that A1 and A5 are joined together and A2 is joined to A3. Because of this you can't just repin the DX connectors at the firewall and use the MPFI engine harness. There will be no wiring for the 2 new injectors.


So here's the question -
I've seen the ECU pin-outs all over the place.
Is there any full harness schematics floating around?

 

those "PDF manuals" have them.

 

Didn't seem to find it.

I have a 91 service manual and it has an NICE diagram in the back with all the wiring schematics.

I'm looking for the same, but for a 92~95 Si.

Anyone here have the helms for the EG and know what I'm looking for?
Can you scan the pages (or a quality digi) please?

 

i'm looking for a 91. could u email it to me?

 

I'll see about bringing the manual to work with me tomorrow to use the scanner here.

 

oh i thought u had a PDF manual. if you could, it just need the automatic seat belts and cruse control sections.
