Ok new to forum not sure where to ask this Question I'm swapping a 8/95 obd1 silver DME S50 to my 7/87 e30 325ic having no luck with finding ecu pin outs for the 95 m3, bin all up and down the "wedophones" site and it seems my pin matching is all over the place from 318's to e34's 525's and so on, I have a purple 413 to replace the OG silver with EWS, getting no fuel & no spark checked wiring three times checked tbs cps ohms all good, I was told 413 will work even without tune chip for the cams: So the question is will the 413 work for the early m3's or are the pins totally different? and where can i find the correct pin out for the early m3's
