Hi All,
Really hoping someone can help me here.
I'm trying to wire up my C20LET engine into a 1.0 12v Corsa B as per the tutorials online, however my wiring and relays appear to be different.
My wiring loom wires are :-
Red/Blue Thin
Red/Blue Thin
Red/Blue Slightly Thicker
Brown/Red
Green
Red
Black/Brown
Blue/Brown
Brown/White
Black (have left this in the engine bay)
The tutorial pictures show two purple relays in behind the glovebox, mine has one purple relay and one blue relay. The wires to each are as :-
Purple Relay (Fuel Pump Relay I think) 90565944
Red/Blue (Thick)
Red (Thick)
Black/Brown (Thin)
Red (Thin)
Blue Relay (Googled relay number, it appears to be for the fog light??) 0332019452
2x Black/Blue
1x Black/Blue
1x Brown
2x Grey/Yellow
1x Grey Yellow
If someone can point in the right direction or even better tell me what to do I would really appreciate it. I have searched and searched but all links seem to be to the same tutorials.
Cheers guys.

I had this issue with my old 1.0 in the end I ran a wire from fuel pump to engine loom with a inline fuse just in case never popped mind, but it wored faultless for over 2 years

It states on the tutorial that it's the other relay that I need to bypass. I only have the one purple relay. Do I just bypass this one?

I had the same on my corsa b. found that the pump relay was live switched (small blue/red wire) where as the ecu for the new engine was earth switched (small brown/red wire)
as a rule on Vauxhalls brown wires are earth, red trace is earth switched.
blue wires with a red trace are ecu live switched
and black wires with a trace are switched by ignition or another switch after ignition.

So Dave did you just completely bypass the Corsa fuel pump relay and just used the LET relay?

In fact my fuel pump relay doesn't even have a small blue/red wire. The switch wires are coloured red and black/brown.

Aidan - that relay has different wiring to mine. You have the two blue/red wires that need bridging. My wires are black/brown and red.

no just swaped the earth and live wires so it wored from the output from the new engines ecu. running stand alone ecu now so just the corsa's relay which is where yours is along with 3 others, one was the cooling fan one doesn't seem to do anything? and cant remember what the last one did?

It is mate. I found the fuel pump relay in the main fuse box. It's a X plate 1.0 12v so wondering if it's anything to do with being one of the last made.
