Im wanting to replace all three relays on the drivers fender/strut area. I wrote all the part numbers down and only one of them cross ref in the pelican parts cat. It came up as a relay off an E34 ?? Does it really matter as long as there is a 5 prong and two four prongs ?? Real oem isnt any help either as it just shows pics w/. no locations........I think Im having a intermitant hot start issue w/ the main relay, has no spark sometimes, if I pull the relay, tap it and let it cool it starts...weird. mine currently are yellow , orange and yellow in color.
