Hi I have put a vs v8 efi auto into a vn v6 have had the memcal remapped to bypass bcm as I don't have one in it. It runs and drives but once it gets to 3rd gear it doesn't up or down shift and engine light comes on just before 3rd gear and stays on until I have turned the car off, turn it back on and it's gone but it does the same thing!. I can't do a diagnostic check as the wiring loom hasn't got the diagnostic plug, the have it in the vn loom but not this one!, plus can't hook speedo up as it is already hooked up and goes to the vs loom and to computer!, so I need help wiring up a diagnostic plug, so I can find out what's wrong with the car and speedo!!, getting annoyed with the car lol
