Only sensors I am running is the coolant and throttle position as far as I remember. If you are running A/C or P/S you will need the idle up and maybe a vacuum sensor, mine has neither so I am not sure.

It was me, and it is simple. That diagram only shows what was modified to connect the Sigma loom to the TR/TS magna engine loom. The rest of the wires from the ECU are as standard. For more in-depth about it, check out my GN build thread, link in my signature.
While we are on the subject. I have two ECU's They have different part numbers.
AW335189 is definitely from an Auto (could have been a TS. It had an additional bracket on the inlet for a plug leading to a knock sensor. Not sure if the TR had this)
AW319647 This one is from a TR manual
I have read differing opinions with regards to running an auto ECU in a manual car. Some say it doesnt matter...some say it does.

It shouldn't matter what the computer was from, just so long as the wiring is correct for the application. As Jason (A112H) said, one of the wires is either grounded or goes off to the neutral safety inhibitor switch depending n if you have an Auto of Manual you are running in the car.

Can anyone tell me what this gizmo is.. Looks like a vacuum operated switch, the wiring comes from the ECU, through this switch ,then disappears into the main injector/sensors part of the wiring loom
I was hoping to leave that part of the wiring loom intact, because I could not see any point of pulling it apart.
I'm not 100% on it, but from playing around with TN and TP Magnas in the past I do know that the vacuum lines for the charcoal cannister are connected to a switch like this, which is then controlled buy the ecu.
confirmed, it s ecu control of carbon canister purge. for brevity i just went back to vacuum control of purge.... and because i lost the said ecu contrlled solonoid.
Yep, it is a purge valve. One side goes into the charcoal canister, the other into the throttle body. It opens up when the throttle opens up to burn excess petrol vapour.
i thought it switched on when the engine runs to intake the stored vapour from the carbon canister that was built up from expansion of the fueltank due to temp or fill up... and switched off when the engine is.
