Sorry for the lack of pics, but basically I made a hybrid engine loom from a TF and grafted it onto my F engine loom, so that I didn’t have to change or alter the main body wiring loom.
Added complication was the fact was my car has factory air conditioning ( retro fitted by me and ABS also retro fitted by me )
Cross referencing between two different wiring diagrams and working out which wires went to where was time consuming, also having an eureka moment when I realised that MEMS 3 cars control the heater functions of the lambda sensors directly, making the relay in the Engine management control relay redundant, avoided a possibly costly mistake.
This took around three days including testing to ensure wires went to the correct points. It also helped having two spare complete MGF looms and a Rover 75 loom to pinch correct colour wires, pins for ecm connectors etc.
Refitted to car, connected up, linked MEMS 3 to immobiliser using PScan, fired up first go.
Just need to weld in a second lambda sensor boss on my exhaust and I will be fine to go
