UPDATE - Well we dint have any real problems with the loom. Started at 7pm and finished by 10pm.Finished removing cab loom in engine bay and removed the lot.Then stripped the rad out of the cab.Then fitted the rs loom which all sort of slotted into place.Just got a few wires to solder on (back lites,fuel pump,immobiliser and roof clock)then the loom is ready to plug in. I chopped out the old speaker wires as then there was less wires to run and im going to put a good system in it when i got time and money.Got the main dash back in too. Fingers crossed engine should be runnng end of sat.
