Uno turbo ecu wiring problem

Post by Hotx19 on Sun Jan 18, 2015 11:23 pm

Hi guys
I bought a x19 with a mk1 uno turbo the wiring looms for ignition and fuel are shot
I got both new looms and ecu and ignition boxes
Ever thing plugged in ok to the the sensors but aim having trouble working out where to power up the looms
I have 3 main plugs I can't work out they must plug into the rest of the uno loom
I need to know what these need power wise
Any help would be great

3 wires red, blue, green

White 3 wires 2 plug wire no 57 and no58

Single heavy wire comes out near afm plug and fuel pump relay
Hope fully some one can
Thanks
John

Thanks I've seen that
It still doesn't tell me where the wires I have should go
It's more about the sensors
But thanks any way

First pic - green wire is the digital boost gauge signal, not needed in your application I suspect!

As Jas said - green wire not used.
Single white wire is live, double white is from starter throw wire (runs the fuel pump on cranking)

If it's the one pointed to by the green arrow in the below it connects to the "-1" side of the ignition coil



Would love an Uno-turbo powered X1/9 Cool

Is that wire on the ignition or fuel loom John?. Is it the one circled in white?

Those X19's can be a right pain in the arse Jas. lol... http://s250.photobucket.com/user/dallaraturbo/library/?sort=3&page=1

Hey Charlie
You have some nice cars their
Out of interest why did you modify the inlet manifold it looks like your using a mk 2 lower manifold adapted to the mk1 with the rail and injectors any reason for that?

Good to hear you got the lump going John, well done. That inlet I got from Ben (Minty) or here, and the plan is to use it on a Punto GT lump so that I can retain the Mk1 plenum (that looks and fits so much nicer in the back of an X) and use any injectors.

Well worth the hassle in my book - if I could find an unfinished project X1/9 turbo conversion for sale I'd find it VERY hard to resist Twisted Evil
