As above, i need to know were to plug this in, as ive looked, and cant seem to see it to well, ive took the black cover of top of engine.

Its a 120bhp 8v 1.9

I bought second hand box hence why i have no idea as it has no instructions lol

Thanks in advance.

Depends on the type of tuning box i think, but it will probably plug into the common rail across the top of the engine - take the cover off and the connection is on the righthand side of the engine

Its got 2 plugs on it, 3 pin ones i belive them to be.

Ohh right, nice one i was on the right tracks then, where does the other plug go? As i have 2? And how do you get them plugs out? as i tried and was proving difficult lol

Thanks again,

You need to plug it into the rail (and connect it to the battery if the unit needs a power source)

The rail is down the back of the engine right next to the EGR... Proper paint to get to the first time.

Make sure and conect it round the right way...! if you put in on back to fron the engine will rev up to about 2k and not be responcive to the throtal... it will also log a fault code. Swapping it round will sort it all out if that happens...

This was the connector down the back of my 1.9 120 in my astra...





Hope that helps

They have a clip on top which you press down and it should come right off...

The other plug may be for the boost sensor or the maf.. Not 100% sure...

What box have you bought?

[Dai69]

One plugs into the rail , the plug that you remove to plug the tuning box in goes into the other plug on the box (one is a plug, the other is a socket)
