So I?m swapping a Sr20det into my 93 240sx with the 62 ecu. It?s my first time doing anything like this so I need a bit of help. First off my harness was cut pretty bad so I?m just trying to get it put back together. I had to buy a new ignition chip and connectors because they were cut off I used the wiring diagram from wiring specialties so I?m pretty sure it?s wired in correctly. I?ve tested my grounds into the ecu and into the ignition chip and the grounds all seem good. Looking at all the wires that aren?t wired into anything I found that my ecu ECCS relay wasn?t wired into anything I don?t know where to wire it into and would that cause no spark? I also found that my eng cont fuse was blew I replaced it and it hasn?t blew yet so I?m not sure why it blew in the first place. If someone could help that would be great.
