BitchinZ Posted March 29, 2014 Share Posted March 29, 2014 (edited) Hello. Just need a little L28ET/Z31 swap help/clarification. I have a 77 280Z. Swapping in an 83 motor, harness, coil, FPR etc. Also doing Z31 ECU stuff at the same time. Does the B/W wire coming from the 83 coil in this first picture, connect to the B/W from the white plug in the second picture? Then does it need to be connected/ran to the ignition? This is the diagram Im using - Also what is this lttle box and is it still needed after the swap? Edited March 29, 2014 by BitchinZ Quote Link to comment Share on other sites More sharing options...
ctc Posted March 29, 2014 Share Posted March 29, 2014 (edited) Does the B/W wire coming from the 83 coil in this first picture, connect to the B/W from the white plug in the second picture? Then does it need to be connected/ran to the ignition? Yes, do a quick continuity check between the B/W wire on the connecter and the appropriate pin on the EFI relay and you will be good to go. I used the lead that feeds the condenser at the distributor as the ignition hook-up. Simplified my installation some as there was already an ignition wire that fed the old coil near by. Saved running extra wire. My reading of some threads here deemed the condenser a non-critical part. Edited March 29, 2014 by ctc Quote Link to comment Share on other sites More sharing options...
