Hello
Due to a cock up on my behalf. I now have a Tunit VCR tuning box for sale.
I bought the one from Barry on here, but i assumed the connection would be the same (they are not)
My later 2004 164bhp d4d engine has a 6 pin connector on the end of the fuel rail.
This box fits the earlier 3 pin connector (its in exactly the same location)
It comes boxed with instructions and connection harness.
You can still buy these direct from Tunit at a cost of £460 delivered
I paid £200 delivered, so will do the same if a club member wants it. just check how many connections you have on the sensor.
I contacted Tunit direct and they confirmed I can't just change the harness as the box is different too.
If you are close enough for collection il even fit it for you.
It should fit the later D4D Colorado too. Just check your fuel rail connection.
