c20xe wiring

[Dicko]

what does what basically, fitting into a corsa gsi. wired up as i expected it to be and getting no fuel or spark. so can somebody confirm these for me plz!

red/white?
blue?
blue/red? (poss fuel pump)
blue/red? (maybe also fuel pump?)
black/red? (maybe +ve)
black/brown?
brown/blue?
brown/white?
brown/yellow?
green? (tacho)
black/green?

[Ste_Nova]

red/white
blue = temp
blue/red thick = fuel pump
blue/red thin = speed sender
black/red = starter
black/brown
brown/blue - ecu light
brown/white ecu diag
brown/yellow = evu diag
green = tacho
black/green

i think the unknowns are autobox and air con

[Dicko]

hmm

so where does it get its main +ve feed from?

also the red/black? the corsa has a seperate loom for the starter which wev conected, and we cant find the other end to this red/black on the engine loom :roll:

[Ste_Nova]

black sleved wire direct to battery (if it's a cav/cally loom)

[Dicko]

ye the big f.off thick wire :D

ye thats conected to +ve on battery via a fuse.

anyways of testing if ECU is powering up properly

[Dicko]

more to the point

what colour is the switched live on the 20xe loom? cant see any black wires that usualy give the game away :oops:

[Ste_Nova]

anyways of testing if ECU is powering up properly

yeh ecu light coming on

[Dicko]

:twisted: bastid lol but good point ;)

what else wud i need for a spark

iv found a thin blac kwire by the coil that doesnt go to anything :s

also still no switched live anywhere

[Dicko]

ok,

brown/blue
brown/yellow

defo connected but no ecu light :-/

[Dicko]

engine now running 8)

i wont ask why the switched live wire was next to the coil :roll:
