It's built in to the flasher switch mate, you have been given the wrong one if it doesn't fit. What year is the van?Thats cool mate, but, i just need to know where 21 is, got no reference to go by.....got no manual to refer to, so im blind, what i have been supplied will not fit into the hazzard switch, so it must be relay 21 which is ????
Thanks for the reply mate anyway.....take care
