thanx that's great, the bosch # for the hazard turn signal relay is P2020-13252, i checked and it seems to be the same relay for the 450 sl, 450 sel, and 280 se, i couldn't find the 450 se (probably the same as the 450 sel?), thanx again, just tell me how much you want for the wires and the relay, do you know if the headlamp bezel is the same? regards, Andrew
