speed delimiter?? thats no where near the main relay coil curcuit, or the fuel pump relay.
Its still playing up though, runs fine for a while, then it starts clicking like mad, almost like its in a diagnostic mode, but the connectors are not crossed, and the fans dont come on, the only things that are effected are the boost solenoid, but then thats run by the main solenoid anyway, so if that goes a bit wonky then so will that one.
I think i will rewire the main relay plug and see if its just a dodgy connection.

I dont know where the de limiter is, its not in the main wiring loom at all, i havent even tried to go over the limit to be fair, so i dont know if it has one, and is working.
I dont recall seeing anything on the back of the dash clocks either.
the only thing thats out of the 'norm' is the black box that sits inside the ecu.
