I found a diagram with the pin numbering

It is the wire that goes from pin 87 of relay 109 to pins 1 and 2 of the ECU connector. The measurements I described above will show if the problem is in this area. I'm attaching the wiring diagram just in case. AKU flow diagram.pdf You need a screwdriver bent at 90 degrees and the airbag is removed quite easily.

After removing the connectors from the ECU, proceed as follows (as a precaution when removing/inserting the connectors, remove the negative battery terminal): - clean the contacts with contact spray (use a dedicated spray, nothing else) - identify the pin numbering in the connector. At the moment I don't have a numbering diagram, I hope the pins are numbered right on the connector. - reconnect the negative battery terminal - with a multimeter, check the resistance between the negative battery terminal and pins 4 and 5 of the ECU connector. It should be very low, around 1 ohm - check with a multimeter the voltage between the negative battery terminal and pin 37 of the ECU connector. It should be equal to the battery voltage.It is a permanent voltage regardless of whether the ignition is on or off. - turn on the ignition and check with a multimeter the voltage between the negative battery terminal and pin 1 and 2 of the ECU connector. It should be equal to the battery voltage. Depending on the results of these checks, we can isolate the area where the interruption could be.

Thankyou so much for your reply. I have replaced the air filter and is clean, new fuel filter and fuel pump and new plugs but every year they were black previously. The only OBD-2 code showing was a fuel tank sensor which makes sense as shows constantly empty!! Probably damaged it when doing fuel pump after I looked at where it is located. No other codes have come up. I was thinking of replacing the lambda before cat. I have someone currently helping me with welding the new flexi on (as the repair kit didn't fit at all!!) so that will be air tight etc. Wiper is now fixed and clearing. I did a new brake cylinder - now the brakes are binding slightly on that side I think and handbrake is solid with 1 click so I need to look at this tomorrow, really appreciate your advice on that. Fingers crossed the exhaust system now being sound will mean emissions will sail through, have also taken it for a good run and dropped some additive in the tank.
