It was a straight swap, I don't think I had to change the relay but it was so long ago I can't be sure, the relay should say on it if it is ok for 4 X 21w bulbs.  Later models have the  hazards linked to the parking light position on the ignition switch which you don't get if you just swap the switchgear but not really a problem.
