Guys, we're nearing the end of my questions here. ..

My S13 ECCS printout shows a red wire leaving the ECU from pin 4 and entering the ECCS relay at Pin 2. What does that wire do? It terminates in the fenderwell area on a Nissan along with the ECU power, backup power etc.. I don't see any instructions on where to hook it up but I have a feeling it's important. (looks like a signal for the ECCS relay) what a nightmare. The ECCS feeds the ECU which feeds it.

My car ran today for the first time. It sounded like absolute garbage but it ran.

Also, if someone is feeling generous, a testing method to test functionality on the CAS.

Please help guys. I have over a year in this project.

Alex
