coolant wireing problems

[pul16v]

hey guys haveing trouble wireing a e16se in to my 1.2 spi well only haveing trouble with the coolant
the problem im haveing is ive connected the wires up in the engine bay which i can test inside the car then i connect the 2 blues together that are in the foot well ( where the old ecu used to be ) then when i check at the clocks there is no volt age there at the blue wire
my question is does it change wire colour after the old ecu which is now not there

and has anyone has this problem ive put voltage to the clock guage and that moves and the sensor on the engine is giveing a voltage just havein great dificluty connecting the two lol

any help appreciated
cheers phil:thumb:

The blue wire doesnt supply voltage, its an earth.

Have you run the engine yet?
Dont want to state the obvious but the gauge wont move until the coolant warms up.
You should get continuity if you put a meter across the wire.

ye the engine runs and ive waited 4 the fan to kick in just so i knew it was warm enough to register and still nothing getin abit pissed off now cos it worked with the 1.2 in and all ive done is connect to the blue wire that the 1.2 used and the two blues in the foot well is that right ?

also a symbol that looks like (!) is staying on on the dash its on the left hand side on the poverty clocks its next to hand brake and battery

touch a screwdriver off the sensor and the manifold or somthing that will earth, get some one to sit in car an look at gauge it should go off the clock, think ignition has to be on, also your thermostat could be stuck open and just running very very cold mine did that.

The sender aint wired into the spi ecu... thats a different sender.
The one for the dash goes straight to the dash.

In the engine bay there should be the original blue wire that clipped on the inlet, fit that to the sender on your e16se inlet.
And it'll no doubt work fine.


The ! symbol is low brake fluid.
