Well i sent my my loom to Rubjonny who does his thing.. but when i received it back i had no idea where most things went.. RobJonny then promptly sent me a PM with this info which should benefit a lot of people wishing to do lets face it the most common install in a mk2 chassis..
This should help with labelling the loom up for a faster install when on the car
small bit that goes on the engine:
2 & 3 pin plug furthest away from round plug - idle & tps plugs on the throttle body
3 pin plug near round plug - dizzy
2 pin white plug - white coolant sensor side of head
single spade connector - black coolant sensor side of head
ring terminal - bolt to rear of head
3 pin & 5 pin plug - isv and fuel rail
blue wire with single spade - large blue or brown sensor on filter housing (has black outer sheath, peel back the big rubber boot to check wire colour)
yellow wire with single spade - large white sensor on filter housing (has black outer sheath, peel back the big rubber boot to check wire colour)
green/black single spade - small white sensor on filter housing
fusebox:
4 main fb plugs will only fit the sockets they need to go in due to the layout, pin orientation and the locking peg on the back
single pin with large spade and red wire - Z/1
single pin grey/white wire - diagnostics
3 random single wires - mk3 dash so unused
engine bay:
7 pin plug near ecu connector - the old mk2 tci-h unit
2 pin and 4 pin plugs near fusebox plugs - inlet temp and lambda
2 pin plug on its own with red/white and brown/white - outside temp sensor in passenger side inner wing
brown ring terminal on its own - battery -ve
2 pin plug red/black and blue/black - reverse switch
single pin plug blue wire - alternator wire (the blue wire on mk2 lighting loom near battery +ve is now unused, or you can use this instead whichever is easier)
3x 3 pin plugs near big round plug - knock sensors and crank sensor. the 2 knock sensor plugs are the ones that are the same shape, and are colour coded to the knock sensor plugs
chunky red/black wire - starter motor
diagnostics and immob box:
black - ign live
brown - earth (i use the stud on the a pillar with 13mm nut)
red/white and brown - live and earth to ciggy lighter wires
